5 Battery Module Assembly

The following instructions include:

• Preparation and assembly of the battery cabinet modules

and internal wiring.

• Interconnection of the PCS DC and communication cables

to the battery cabinet.

Note: Overcurrent protection of the DC source is provided

internally as part of the integrated battery system. No

external DC disconnect is required.

5.1 Battery cabinet ground bus

CAUTION! A torque wrench is required to ensure the

power cables are terminated to their specifications.

Over-torque can damage the DC breaker and/or strip the

threads on the copper bus bar posts. Under-torque can result in

an arc fault hazard, and risk of fire. Damage as a result of

improper termination is not covered by the manufacturer

warranty.

1. Mount the four ground wires provided in the battery

module grounding kit into the 4-position ground

distribution block.

5.2 DC negative power terminal assembly

2. Route the DC negative power cable from the PCS through

the cabinet port and mount to the DC negative power

terminal.

3. Mount the two DC negative battery module power cables,

referenced A3, (as provided in the battery cable kit) to the

DC negative power terminal. Offset each power lug so

that a flush electrical contact is made between each of

the lugs.

4. Secure the DC negative power cables to the

power terminal using the washer, lock washer, and

hex nut provided. Torque the nut to 35 in/lbs.
