Wiring and Connections

This chapter provides cabling details and notes on cable sizing for DC applications with respect to the product.

NOTE: Refer also to foldout drawings located at the rear of the manual.

5.1 Safety

Precautions

WARNING
Hazardous voltages are present at both the input and the output of power systems. Ensure that
input power and output power is removed before attempting work on the CXC’s connections. Use
a voltmeter to verify the absence of voltage. Clearly mark the correct polarity of the battery leads
before commencing work on DC connections.

Refer to the previous (Installation) chapter for additional safety precautions.

5.2 Front

Access

All wiring connections are accessible from the front of the panel and rack models.

NOTE: Connections for the CXCM (4RU plug-in module) are located on the system shelf – see shelf manual.

For example, to gain access to the terminal block connectors for the rack model:

1. Turn the two front panel latches (spring-loaded) counter-clockwise.
2. Tilt the front panel forward and down.
3. Loosen the CXC’s rear screws and remove its rear plate.
