Making Electrical Connections

Important Safety Instructions

Danger! Adhere to the “Important Safety Instructions”

presented at the front of this document.

Wiring Considerations

All AC input and 400V DC output wiring, branch circuit protection,

and grounding/earthing should follow the current edition of the

American National Standards Institute (ANSI) approved National

Fire Protection Association's (NFPA) National Electrical Code (NEC),

and applicable local codes. For operation in countries where the

NEC is not recognized, follow applicable codes.

For wire size, branch circuit protection, crimp lug, and general

wiring recommendations; refer to System Application Guide

SAG584001200 and the Battery Cabinet manual

(IM58400120090).

General Grounding/Earthing Guidelines

Danger! Failure to follow proper grounding/earthing

procedures can result in electric shock hazard to

personnel and the risk of fire, should a ground fault

occur.

For grounding/earthing requirements, refer to the current edition

of the American National Standards Institute (ANSI) approved

National Fire Protection Association's (NFPA) National Electrical

Code (NEC), applicable local codes, and your specific site

requirements. For operation in countries where the NEC is not

recognized, follow applicable codes.

Refer also to the grounding/earthing procedures in this document.

Output Ground Configuration

This system is configured for High Resistance Midpoint Ground

(HRMG). Ensure the HRMG lead is properly connected to

ground/earth per the instructions that follow.

Cable Routing

The Power Module/Bay and Distribution Module/Bay are provided

with top plates that have cable routing holes that either accept

conduit fittings or corded connections.

Torque

Torque all connections as specified in the illustrations presented in

this section.

Connection

Refer also to “General Grounding/Earthing Guidelines” on page 4.

Supply a grounding/earthing lead from site ground/earth to the

rack ground bar. Refer to Figure 3 for connection point.

Figure 3. Power Module/Bay Rack Frame Grounding/Earthing

Power Module/Bay HRMG Connection

Refer also to “General Grounding/Earthing Guidelines” on page 4.

A ground lead exits the rear of the power and control section in the

Power Module/Bay. This lead MUST be connected to ground/earth

for proper operation of the HRMG circuit and the ground fault

detection circuit. Refer to Figure 4 for location. THIS LEAD IS

FACTORY CONNECTED TO THE RACK’S GROUND BAR.

Caution! Failure to terminate this conductor to

ground/earth will render the system ground fault

detection circuit and the ±200V DC voltage reference

inoperable. It is essential to properly bond this lead to

ground/earth.
