IMPORTANT SAFETY AND INSTALLATION WARNINGS

WARNING: DO NOT ATTEMPT TO SERVICE THIS PRODUCT YOURSELF AS OPENING OR REMOVING COVERS MAY EXPOSE YOU TO DANGEROUS VOLTAGES OR OTHER HAZARDS. REFER ALL SERVICING TO QUALIFIED SERVICE PERSONNEL.

The Lindsay Broadband LBPS-250-ACPSU-HFC90V and LBPS-400-ACPSU-HFC90V AC Power Supplies are housed in sand blasted cast aluminum housings which use metal hardware. All interior and exterior metal parts have smooth surfaces with rounded corners. There are no sharp metal corners or edges that could cause injury to any personnel. When properly installed, the entire exterior of the housing is at ground potential and no shock or electrical hazards exist. When the housing lid is open for set-up, maintenance, servicing etc., potentially harmful AC and/or DC voltages may be present at many contact points inside the housing. Please become familiar with the internal circuits and the voltages that exit at all points of potential contact before any work is begun. Field personnel must be aware of these hazards and caution should be exercised to avoid contact with all contact points throughout the enclosure that are not at direct ground potential (mechanically fastened to the housing chassis). Lindsay Broadband strongly recommends removal of the AC interrupt jumper inside the LBPS whenever possible with the lid open to remove shock hazards to personnel.

WARNING - *Please note that even with the AC interrupt jumper removed, there will still be line voltage present at the HFC input terminal and its associated circuitry unless the AC power has been removed at the power inserter in the HFC system prior to the LBPS. The output power ports are weatherproof and UL approved. MOUNTING: Mount this product only as described in the installation instructions, otherwise it may fall causing serious personal injury and/or damage the unit. Use only the brackets supplied with the product. Do not use attachments not recommended for this product as they may cause hazards.

SECTION 1 PRODUCT DESCRIPTION

1.1 Introduction

This manual is written to give instruction on the installation and service of the Lindsay LBPS-250-ACPSU-HFC90V (250W) and LBPS-400-ACPSU-HFC90V (400W) AC Power Supplies. The first section details the product description with block diagrams, photos and pictorials. The remaining sections outline the installation/setup instructions and specifications, and will refer to both models generally as LBPS or specifically as LBPS-250-ACPSU-HFC-90V or LBPS-400-ACPSU-HFC90V.

1.2 General Description and Function

This AC Power Supply leverages the general availability of AC power on the cable operator’s HFC network to provide system power for Small Cell radios and associated equipment that need to be powered outdoors with an AC voltage source from the CATV plant.

Sourcing from the CATV AC power supply, the LBPS AC Power Supply delivers a regulated quasi-square voltage to it’s output ports by the use of a uniquely configured and actively switched multi-tapped autotransformer.

The LBPS-250-ACPSU-HFC90V has two output ports supporting 250W total load, and the LBPS-400-ACPSU-HFC90V has four output ports supporting 400W total load.

1.3 Housing(s)

A rugged sand blasted die cast A360 aluminum housing of clamshell design is used.

All exterior metal components mated with the die cast aluminum housing are manufactured from non-corrosive materials.

An ‘O’-ring gasket provides an airtight seal between the housing lid and base. IP68 (15 PSI for 10 seconds) ingress protection with the bayonet power ports in an unmated position is retained.

Externally, the housing base has installation mounts, 2 bayonet AC power ports and an ANSI/SCTE-91 compliant 5/8-24 threaded HFC input port for KS type connection to the HFC network. The LBPS-400-ACPSU-HFC90V has 2 additional bayonet AC power ports installed in the base.

Each device uses Conec 17-400173 20A three terminal power receptacles to deliver power to external devices. A mating Conec 17-400283 three terminal power plug is supplied for each receptacle. The output receptacles mate with their plugs with a twist bayonet action.


2017 Nov 15 5 of 14 Rev. 2

Lindsay Broadband does not specify any particular power output cable for use with the Conec plug.

If preferred, Lindsay Broadband will install a customer supplied power cable (E.g. Nokia Flexi Zone etc.) or a SJOOW 3-conductor #14 AWG cable to the supplied Conec plug at a nominal cost prior to shipment of the unit.

Internally, the housing bottom contains the HFC interface board, multi-tapped autotransformer and either two (LBPS-250-ACPSU-HFC90V) or four (LBPS-ACPSU-HFC90V) AC output ports.

The housing can be strand mounted, with or without hanger brackets.

Each unit is identif ied by its model number which is indicated on weather resistant label that is aff ixed to the exterior top lid of the housing:

Each unit is also identif ied by a weather resistant unique individual serial number label that is aff ixed to the exterior right-side corner of the housing base. The serial number is printed both in alphanumeric and bar code format. Date code information is also included on the label.

All labels are permanent, water, heat and smudge/stain resistant.

1.4 HFC Interface Board

The HFC Interface Circuit Board is located in the housing base and provides the interface connection to the HFC network.

The following features are provided:

• Terminal post for connection to the HFC system coaxial connector.

• Standard plug-in SVP type surge protection.

• AC interrupt jumper to disconnect plant input power.

• A polarized connector to disconnect the autotransformer module.


2017 Nov 15 6 of 14 Rev. 2

1.5 Autotransformer

HFC power is delivered to the load by use of an autotransformer constructed with f ive winding taps, allowing the transformer turns ratio to be varied. Depending on the input voltage, the taps are actively switched to maintain the output voltage within a small window.

The autotransformer input/output can be disconnected from the HFC board via a polarized connector.

1.6 Output Fusing, Wiring and Connections

The LBPS AC Power Supply employs a single ¼”x1¼” 3AG fuse to protect the

Black output conductor of all the outputs. White and Green conductors are both tied to chassis ground.

The Black, White and Green wires are routed to the two or four parallel connected AC output weatherproof three terminal receptacles mounted in the housing base

The LBPS output connectors mate with their plugs with a twist bayonet action.

SECTION 2 INSTALLATION

2.1 Pre-Inspection

Upon receipt of the LBPS AC Power Supply inspect the carton for any external damage. If damage is present inspect the LBPS exterior for damage. Report any apparent damage to the shipping agent and Lindsay Broadband sales office.

2.2 Installation Overview

Installation of the LBPS is similar to the installation of a line extender or other piece of CATV equipment. The LBPS must be connected to the HFC system via a power inserter since the AC port is not RF filtered. The Lindsay LTE-PI power inserter is required. Connecting the LTE-PI “AC” port to the LBPS input maximizes the RF isolation of the LBPS from the CATV plant.

2.5 Installation Procedure

1. For installation, the following are required: the LBPS, a LTE-PI Power Inserter, output bayonet plug connector(s) prepared with the correct outdoor rated cable(s), hardline coaxial cable and a KS connector suitable for the job.

2. Prior to installing please consult with the system planner to verify that the install site will support a fully loaded LBPS. This will depend on:

• the pre-existing load on the system power supply.

• the magnitude of “IR” losses (from coax and passives) between the system power supply and the LBPS.

Note that although the measured site voltage may be above the LBPS minimum operating input voltage prior to connection, it may fall below the minimum voltage after connection due to the factors above. Please verify with the system planner.

3. It is recommended to plan for some margin above the minimum operating voltage while the LBPS is loaded to allow for unplanned events that could cause the system voltage to momentarily fall below the minimum.

4. Disable the system power at the installation site and install the LTE-PI Power Inserter as outlined in Section 2.2. Remove the AC interrupt jumper inside the LBPS (see Section 1.7, block diagram and pictorial).

WARNING - *Please note that even with the AC interrupt jumper removed, there will still be line voltage present at the HFC input terminal and its associated circuitry unless the AC power has been removed at the power inserter in the HFC system prior to the LBPS.

5. Using the diagrams in Section 2.3 as a guide, install the LBPS in its f inal location. If using hanger brackets, the existing strand clamps should be left in place to act as spacers allowing the same bolts to be used.

6. Using a length of suitable coaxial cable and a KS connector, complete the connection between the LTE-PI Power Inserter and the LBPS.

7. Without connecting a load to the LBPS, re-install the AC interrupt jumper and verify that the LBPS output voltage at the output power receptacles is correct.

8. Remove the AC interrupt jumper from the LBPS again.

9. If the output bayonet plugs are pre-wired for the load equipment, then connect them now to the LBPS output receptacles. Otherwise, wire the bayonet plugs to the load equipment as per your load specification and


2017 Nov 15 12 of 14 Rev. 2

the LBPS output information in Section 2.4. Plug the load cables into the LBPS output receptacles.

10. Assuming the load equipment is ready to be powered, re-install the AC interrupt jumper inside the LBPS and verify that the equipment is powered with the correct voltage.

11. (Optional) Silicone Grease can be applied to the exposed part of the ‘O’-ring before swinging the lid back into place. This will reduce any tendency of the ‘O’-ring to stick to the lid and ensure a weather-tight seal. To be clear, use Silicone Grease, not Silicone Sealant, nor any other type of grease.

12. If the EMI gasket has any frayed or loose ends, tuck them back into the channel and close the lid.

13. To ensure proper alignment of lid and base, f inger start all lid bolts before tightening any of them. Using a torque wrench with a ½” socket, tighten the lid bolts gradually, alternating diagonally to avoid stress or warp on the housing sealing surfaces. The lid bolts should be tightened to 17-ft LB or 24 Nm. This torque is easily met by using the box end of a combination wrench, but cannot be reached using a nut driver.

14. (Optional) If the MSO’s policy specifies, apply self-fusing tape, Eg. Polyflex SFT-150 (Lindsay Broadband Part # 3-186) to connections.
