Safety - Allen-Bradley 1407-CGCM User Manual

This chapter provides a suggested set of steps that the user can follow in
commissioning a CGCM system. This assumes that you have:
• evaluated the system design needs.
• selected a suitable instrument wiring arrangement.
• followed recommended installation procedures.
• configured the RSLogix 5000 software and programmed the host Logix
controller.
• configured the ControlNet network.
• performed the initial configuration of the CGCM unit.
This suggested procedure is a basic guide that can be altered to suit the needs of
your particular installation.
For additional information on how to perform specific steps, refer to
CGCM Unit Operation, and
are encountered during startup, refer to
procedures, can install, wire and service the CGCM unit and its

sources of power and verify that they are de-energized and locked out.
Failure to follow these instructions can result in personal injury or death,
property damage or economic loss.
primary current applied. Wiring between the CTs and the CGCM unit must
include a shorting terminal block in the CT secondary circuit. Shorting the
secondary with primary current present lets you remove other connections
if needed. An open CT secondary with primary current applied produces a
hazardous voltage, which can lead to personal injury, death, property
damage or economic loss.
