Battery Return Reference lead (BRR) / C.O. Ground cable

The Battery Return Reference cable /C.O. ground cable should be equal to or larger than the largestcurrent carrying conductor in the DC Plant. Since the largest current carrying conductor is normally a 750MCM Cable it has become the normal practice to Install 1 – 750 cable. This Bar at the Primary DistributionCabinet is pre drilled for 2 hole lugs 3/8” bolts on 1” centers.

Generally accepted practices in C.O. Grounding

• The C.O. ground cable should be separated by method of cable brackets or dedicated groundingrack and easily traceable from the Floor Ground Bar (FGB) or Building Principal Ground (BPG) tothe DC Power plant.

• The C.O. ground cable should not be spliced and should be continuous from the FGB/BPGdirectly to the DC Power plant.

• Brass labels marked “DO NOT DISCONNECT” shall be place at both ends of the cable.

• The cable should be designated DC POWER PLANT C.O. GROUND on both ends of the cablesecured to a C-145 cable tag.

• The cable should be Green; however Black and Grey are an acceptable substitution.

• The cable shall have two hole lugs with compression type lugs.

• The C.O. Ground cable should be connected to the extreme right or as an option, to the left inorder to prevent cable mismanagement.

6.0 Inner-frame DC Links

BPE 48- 4000 Modular power systems have tin plated contact surfaces. These surfaces do not requiresanding; simply apply a dry cloth to clean any debris or dirt. Although Tin coated surfaces do not normallyrequire any anti corrosive compound (i.e.) non ox ide a thin layer is generally acceptable.

The two (2) Rectifier Cabinets must be interconnected to the Primary Distribution Cabinet once all thecabinets are secured and have been bonded to frame ground. The left (from Front) rectifier cabinet isready to accept two (2) EC-270, Inter-frame DC links. These links are secured with 5/16 and 3/8 nuts, flatwasher and lock washers as shown below viewed from the rear (right side). Repeat for the other cabinetusing an EC-271 for the top and an EC-378 for the lower Inter-frame DC Link. Torque all boltedconnections per table A which can be found at the end of this document.

Rectifier Cabinets and PDC as viewed from the rear

7.0 AC Input Connections

Each Rectifier Cabinet utilizes 480 VAC, 3 phases and a PE frame ground located behind the removable

panel at the top left hand side of the cabinet, behind the cabinet access door. Each Rectifier Cabinet isdesigned for either a bulk/dual input for the entire Rectifier Cabinet. The bulk/dual input is standard andpre wired to power all 10 rectifiers from a single 480 VAC source or by removing the horizontal jumpers;two feeds (A & B) can be brought into each of the rectifier cabinets. If the jumpers are removed, one 3phase feed would supply power for rectifiers 1-5 and the other feed powers rectifiers 6-10. Please refer tothe system schematic for specific details regarding these connections. The input voltage to the system is480VAC three phase (3W + PE Ground). The removable cover must be re-installed after the inputconnections are made, See Below

RECOMMENDED EXTERNAL BREAKER SIZES

Bulk Feed for up to 10 rectifiers Qty 1 – 200 ( 3 pole ) Amp Breaker

Dual Feed for up to 5 Rectifiers Qty 2 – 100 ( 3 pole ) Amp Breakers

Rectifier Input Protection

Each rectifier cabinet distributes the 480 VAC 3 phase power to each rectifier through a three-pole fuseddisconnect. These devices provide two important functions. First, they provide individual input protectionwith disconnect function for each rectifier and secondly, they are current limiting devices. Due to thepotential for high Interrupting Capacity with 480 VAC service, these devices limit possible pass throughcurrents to a safe level. These fuses must only be replaced with a KLKR 30 current limiter or equivalent.These disconnects also provide visual indication via a “red” indicator if any one of the fuses shouldoperate.

2 Connection

The following standards and regulations are applicable to the unit:

EN 61558 EN 60950

VDE 0884

EN 50 081-1 EN 50 082-2

In the standard version, the device and the insulating transformer correspond to

protection class I. The transformer corresponds to the regulation EN 61558 and

the test voltage primary/secondary is 4 kV alternating voltage.

The unit as delivered is ready for operation.

Installation and perfect operation is only possible in the special 3U; 19” rack

(PN: 550828).

The handle on the front panel serve only for pulling out the device,

not for carrying the device.

This device (protection type: IP 20 must be installed in a dry and dust-

protected environment. The cooling air should not be obstructed.

Pay attention to the circuit diagram!

It is necessary to supply the supply circuit with an insulating device which has

to be

- easily accessible if permanently connected;

- easily accessible if it is a plug connection and located close to the device .

Provide appropriate fuses for mains and output cables (size of fuse,

characteristic see technical data)!

Access to the input and output fuses is only possible after opening the unit.

Before connecting up, make sure that the specifications on the type plate and

data sheet agree with the actual mains and battery voltages.

The details in the rating plate and in the data sheet with regard to power

consumption apply to rated conditions of input voltage and the operating mode

“float charge voltage”. The value in brackets is the maximum input current

with maximum input voltage tolerance and in the operating mode “charging”.


44/154


TEBECHOP 12000

Make the mains connection on rack only when the mains supply

voltage is switched off.

The device must be connected with the neutral conductor of the supply power

circuit according to local regulations.

Because of the high energy of the battery to be connected, take special safety

precautions.

To protect the device from overvoltages (such as from lightning strikes), carry

out potential equalisation with sufficient cable cross section (e.g. 6 mm²) on

Rack provided no other measures to protect the device are provided, for

instance building protection.

3 General

The rectifier described in the following is in switched mode technology.

This technology provides sound efficiency and good dynamic control

characteristics in the event of input voltage changes and load jumps.

Since these rectifier units are highly compact designs and can be connected in

parallel, the establishment of powerful electricity supply systems is possible in

conjunction with the 3U; 19” rack.

IPU characteristic (standard)

In order to achieve as high as possible a charge current, power is controlled on

the output side. This means that, dependent on the respective charge voltage,

the output current is adjusted to the maximum possible output power (example

of a 48V device see figure 1).

The IPU characteristic is only active in the operating modes “float charging”

and “ charging”.

In the operating modes “direct feed” and “1,8 V/Z”, it is limited to ratedcurrent (IU characteristic).

Based on the type of battery and number of cells, the output voltage is kept

constant with an accuracy of ± 1 % Based on the type of battery and number of

cells, the output voltage is kept constant with an accuracy of. On reaching the

current limit control changes electronically from voltage to current control.


45/154


TEBECHOP 12000

Figure 1: (IPU characteristic; example: 48V unit)

The consequence of current limitation if applicable is a drop of the output

voltage in the event of a short circuit to < 1 V, the output current is

approximately around Irated. or at Imax , depending on operating mode. This

measure makes the device short-circuit proof permanently.

Mains fluctuations of voltage and frequency (see technical data sheet) and load

changes have no effect on the quality of the voltage and current constancy and

are regulated.

The power factor of the rectifier unit (active power to apparent power) is

regulated to roughly 1 (PF > 0.99 at rated operation). The utilisation of the feed

network is considerably improved in this way and higher output can be taken

from the single-phase net.

The rectifier is equipped with the so-called satellite. This assembly integrated

in the rectifier enables the establishment of a remote monitoring system MCU

1000 / MCU 2000.

Faults are delivered by means of floating contacts via the external evaluation

electronics “MCU”.

Additional information on the duty of the satellite, see chapter 8.

4 Functional principles

The mains voltage fed in through the input filter is converted by the rectifier toDC voltage and supplied to the active filter (PFC). A special control method

takes a sinusoidal current from the three-phase net and provides a constant DC

voltage for the main unit (charge unit) at the output of the active filter.

Rapid MOSFET power transistors in the chopper unit convert this DC voltage

into a rectangular voltage. Control is effected by changing the duty cycle with

constant frequency. The power transmitter serves to separate the potential and

transform the rectangular voltage to the desired output value. Diodes rectify the

voltage and an LC filter is used to smooth the output voltage.

The device is equipped with a hardware overvoltage cut-out.

For switching on and off, the rectifier unit must be operated via the switch in

the front panel.

5 Start-up

Push all rectifier into the cabinet, with the mains switched off.

Switch on the first unit at the mains,

wait for the end of initialization period of this unit,(the end of this period is indicated by the green LED "Operation / “ and

the red LED "Fault/ “) no longer flashing,

now the next unit can be connected to the mains; here, too, you need to

wait for the end of the initialization phase, before the third unit can be

connected to the mains and start up.

All rectifier units must start up individually in order to ensure that each unit is

assigned its own address.

If, for a particular unit, the initialization phase has run without any problems,

then this unit must be withdrawn.

Following a period of approx. 3 minutes which is required for the internal

discharge of the capacitors, the initialization must be carried out again.

Following completed initialisation, the green LED “operation”

“ “ is activated. The unit will then run up to the set rectifier

output voltage with a time delay.

When removing the device, place switch in “off” position first!


47/154


TEBECHOP 12000

The handles on the front panel serves only for pulling out the

unit, not for carrying the unit .

6 Operating modes

The rectifier unit has a total of four operating modes or characteristics, which

can be activated by changing over the operating mode via the satellite bus

(SAT bus) by means of “MCU”.

6.1 Floating level (ErlAd)

Standard operating mode, normal operation setting, float charging with rated

current or maximum current (based on power) up to the voltage limit (seetechnical data sheet). The level of the output voltage is set by the „MCU“.

6.2 Boost level (LAdEn)

Necessary for fast charging the battery. Charging up to the voltage limit with

rated current or maximum current (based on power), see technical data sheet.

The level of the output voltage is set by the „MCU“.

6.3 Direct feeding (dir.SP)

Operating mode without battery (voltage value see technical data sheet). Thelevel of the output voltage is set by the „MCU“.

6.4 Battery circuit test (b.tESt)

Voltage reduction during the battery capacity test in order to obtain exact

measured value (voltage value generally set to V/C). (see technical

specification sheet.)

The level of the output voltage is set by the „MCU“.

6.5 Time-dependent automatic charging

By means of the automatic charging system integrated in the rectifier it is

possible that the unit switches over automatically to the characteristic

“charging” following a power failure. After expiry of the charging time, it

switches back to the characteristic "float charge".

The mains failure charging time is set via the “MCU”.

7 Parallel operation

Parallel operation of several rectifiers is possible and takes place withoutdecoupling diode on the rectifier output.


48/154


TEBECHOP 12000

For symmetrical output current distribution, the rectifiers are interconnected

via the contact “1,2,3(b1)” on the connector strip (“X16”) (parallel operation

connection). A parallel operation tolerance of approximately ± 10% of Irated isachieved in this way in load operation from 30 – 100%.

The voltage and current compensation can take up to 5 minutes in case of con-

nection of an additional unit to the system (self regulating process in 10 mV

steps).

A minimum basic load of > 5% is required with parallel

operation to safely maintain the fault message contact. The

satellite bus connector “RS485” in the counter-connector

system must be plugged with parallel operation using severalracks in order to enable data interchange. In addition to this, the

“parallel operation connection” of the racks must also be

interconnected!

8 Satellite

For further information on the function of the satellite, refer to thedescription no.: 2801.

The satellite integrated inside the rectifier unit monitors the rectifier unitand provides the open and closed loop control functions for it. For the user the

satellite looks like a digital interface to the rectifier unit. The rectifier unit

obtains the required data via this interface from other units of the remote

monitoring system MCU 1000/MCU 2000 to establish the desired operating

state. This requires that the satellite has available the complete set of

parameters for open and closed loop control as well as all data with regard to

the operating states of the rectifier unit.

The satellite is a principal unit in the remote monitoring system MCU

1000/MCU 2000, ensuring that control and monitoring of the power supply

systems is possible via the public telephone network.


49/154


TEBECHOP 12000

The further functions of the satellite, among others, are as follows:

(Faults are delivered by means of floating contacts via the external evaluation

electronics “MCU”)

1. Four adjustable operation modes/characteristics

2. Battery temperature inclined float charge characteristic (incline

adjustable)

3. Unit monitoring with logically combined urgent alarm

4. Mains monitoring with logically combined non-urgent alarm (time

delay of the alarms adjustable)

5. Time-dependent automatic charging (mains power failure time and

charging time adjustable)

6. Current limitation is set in accordance with medium load (IrEG

adjustment)

7 Voltage tracking (UrEG. adaptation).

8 Power management (Po.MA).

9. Serial SAT bus interface via counter-connector system for

communication in parallel operation of several rectifiers

8.1 Standard function

After switching on the rectifiers and an initialisation phase of approximately 30

seconds, the unit runs up to the output voltage saved last (for instance float

charging).

8.2 LED-indication

The following LEDs are provided in the unit front panel of the rectifier:

- (green) "operation"/ " " (LED active: The units operating

correctly)

- (yellow) "mains/data"/ " V " (LED active: Mains voltageavailable; LED flashes: Data

transfer via SAT bus in progress)

- (red) "fault - fuse"/ " " (LED active: Output fuse tropped)

- (red) "fault-unit"/ " " (LED active: unit fault)


50/154


TEBECHOP 12000

- (red) "UA too high"/ " " (LED active: Overvoltage

protection responded)

- (red) "Fan fault"/

" " (LED active: Fan failure!)

For error identification, the relevant error code is shown in the display

and transferred via the “SAT bus” .

(refer to the description no.: 2801)

LC-Display

The 5-digit LC display on the rectifier front panel indicates physical units

(current, voltage, battery temperature or data address) as well as operating

status of the rectifier.

9 Alarms

9.1 Urgent alarm (unit fault SV1)

The message contact “Device fault” of the external evaluation electronic

(MCU) is closed and the control lamp “Operation”/ “ “ LED green is off,

and “Fault device” / “ “ LED red is on.

These signals are internally delayed by approximately 30

seconds.

Device fault (urgent alarm) is dispatched under the following conditions:

- Overvoltage protection has responded

- Temperature too high

- Regulator or power pack defective

- Output fuse tripped – Incorrectly poled battery

9.2 Non-urgent alarm (mains fault SV2)

This signal follows AC undervoltage or mains power failure, the message

contact of the external evaluation electronic (MCU) is closed and control

lamp “mains/data” / “ V“ LED yellow is off.

9.3 Temperature monitoring

The rectifier is equipped with a temperature control on the heat sink which

operates as follows:


51/154


TEBECHOP 12000

Assumption:

The rectifier is operated at rated current.

1. Heat sink temperature continues to rise2. At T >85°C rectifier is switched off

3. LED red “fault device” / “ “ on

4. LED green “operation” / “ “ off

5. Urgent alarm / device fault “SV1” is dispatched.

After the heat sink has cooled down, the rectifier is

automatically reset.

The rectifier is then switched on again.

9.4 Overvoltage protection

In the event of overvoltage (see technical data sheet) the device is switched off.

The overvoltage protection is designed as a battery and device protection.

Switching on after the fault has been repaired is possible when the device is

separated from mains for approximately 10 seconds.

LED red “UA too high”/ “ ” and urgent alarm are also reset during this.

Testing the overvoltage protection is not possible with anexternally controlled power supply unit since the rectifierrecognises an externally fed voltage and fails to switch off as a

result.

9.5 Output fuse-monitoring

Because of high energy of the battery to be connected, an output fuse has

already been installed to protect the device. The control integrated in the

device issues a message once the output fuse has tripped.

LED red “FAULT output fuse” / “„ “ “ on, the message contact “Device

fault” of the external evaluation electronic (MCU) is closed and control lamp“Operation” / “ “ LED green off, and “Fault device”/” “ LED red on.

9.6 Incorrect battery poling

An incorrectly poled battery of the externally connected battery is registered,

messages are displayed, and the internal monitoring prevents the unit from

starting up again. Signalling contact "Unit fault" of the external evaluation

electronics (MCU) is closed, the control lamp "Operation"/ " " LED green

is off, and "Fault-unit"/ " " LED red flashes.

In the LCD- Display, " –BAT- " is shown.

9.7 Ventilator fault


52/154


TEBECHOP 12000

During operation of the ventilator (temperature controlled) an air-current

monitoring system controls the function of the ventilator. If an error occurs, the

following procedure takes place.

• LED red "ventilator fault"/ " " is activated

• Non-urgent alarm (SV2) of the external evaluation electronic (MCU) is

closed and the control lamp “Operation”/ “ “ LED green is signalled

• The rectifier current is reduced automatically to 60 % Irated.

In this way it is possible to operate the unit with reduced power.

10 Adaptation of float charge voltage to battery ambient

The charging voltage of lead batteries, particularly maintenance-free lead

batteries, should be adjusted to the ambient temperature. The temperature

sensor is connected to the connection terminal, i.e.only one temperature sensor

per system. Use a screened cable if the sensor is used externally. The length

should not exceed 5 m. Sensor element- 2 kOhm +/- 2 % NTC.

This function is only available in the „float charging“ mode. U A

at 20°C is automatically established on sensor breakage!

The (tEMP) function must also be activated via the MCU !

11 Fuses

According to the technical data sheet.

Access to the input and output fuses are only possible after opening the unit.
