–48 Vdc CO Power Unit.

Chapter 2 provides installation consideration

information and procedures for installing an optional

second power module, setting the option straps, installing

the –48 Vdc CO Power Unit, providing power to the

power unit, installing a Shared Diagnostic Control Panel

(SDCP), connecting to a CO Alarm System or a

COMSPHERE 6800 Series Network Management System

(NMS), and installing an optional air filter and brackets.

Chapter 3 describes the status indicators on the

faceplate of the power module. It also provides

troubleshooting guidelines and replacement instructions

for the power module, and a preventive maintenance

schedule for the optional air filter.

Appendix A contains interface connector pin

assignment information.
