DVR2000E/EC Hardware Installation- IOM Reference -

This section will discuss the installation of the

DVR2000E/EC hardware. This is discussedin detail in the DVR2000E Installation,

Operation, and Maintenance (IOM) Manual(GPN019 03/06), Pages 26 36.

DVR2000E/EC Hardware Installation- Mounting -

The DVR2000E Installation, Operation, andMaintenance (IOM) Manual(GPN019 03/06),

Pages 26 - 28 provides you the information

necessary to mount the DVR2000E/EC

voltage regulator. Please refer to this

information for:

Size evaluation,

A cutout template, and

Drilling dimensions.

DVR2000E/EC Hardware Installation- Connections -

The DVR2000E Installation, Operation, andMaintenance (IOM) Manual(GPN019 03/06),

Pages 29-32 provides you the information

necessary to connect the DVR2000E/EC

voltage regulator to your generator. Please

refer to this information for detailed

instructions and definitions of each terminal.

Ref: IOM, Page 26

NOTE: Be sure that the DVR2000E/ECis hard-wired to earthwith no smaller than 12 AWG copper wire attached to the

ground terminal on the rear of the unit case.

DVR2000E/EC Hardware Installation- Electrical Connection Notes -

1. In order to parallel with the DVR2000E/EC, a

current transformer (CT) MUST be installed in

the B-phase of the generator and connected to

the CT1 and CT2 inputs of the regulator.

2. If installing a CT, always confirm that the dot-

side is towards the generator as shown in theconnection diagrams.

DVR2000E/EC Hardware Installation- Electrical Connection Notes (Contd) -

3. To disable the droop circuit (Parallel Control),you MUST SHORT Terminals 52L and 52M.

This will be necessary to run the generator as

a stand-alone unit.

4. To disable the VAR/PF Control(available on

DVR2000EConly), you MUST SHORT

Terminals 52J and 52K. This will be necessary

to run the generator as a stand-alone unit if

using a DVR2000EC regulator.

DVR2000E/EC Hardware Installation- Electrical Connection Notes (Contd) -

5. The suggested 0.1 Ohm resistor shown for the

cross-current (reactive differential) connections

may need to vary. This burden resistorshould

have a value approximately (10) times thecross current loop resistance for proper

differential operation. The volt-ampere (VA)

capacity of the paralleling current transformersshould be considered after sizing the burden

resistor.

DVR2000E/EC Hardware Installation- Install Protective Cover -

NOTE: It is highly recommended that the protective cover be installed on the DVR2000E /

DVR2000ECwhenever power is applied to the DVR2000E / DVR2000ECas the heat sinks

on the rear-side of the DVR2000E / DVR2000ECare live when power is applied.
