Warnings
Review all safety instructions and warnings before
troubleshooting the CPS.
Rectifier
Before beginning to troubleshoot the ES664 rectifier, check the
following:
•
Is there an ac failure?
•
Is the ac source connected?
•
Is the input circuit breaker on?
•
Are any LEDs lit?
•
Is the rectifier properly installed in the shelf?
Table 8-A lists indications, possible cause, and the corrective
action(s) to take when a rectifier does not deliver power. Match
specific site conditions to those in the “indication” column and
complete the corresponding corrective action.
Warning
The modules intended for use in the CPS shelf are not suitable
as disconnect means and the spacings of the shelf backplane
do not provide adequate spacing to act as a disconnect means.
AC input voltages are provided to the CPS via input cable.
Ensure that the circuit breaker for the ac input is disconnected
while installing or servicing this equipment.
Note
Before working on any output circuit, turn off circuit breakers
on the BPS output.
