the system will notify you when any of
the three power modules fails. Con-
nect JAR1 to a micro-switch to turn
off the alarm that is activated when a

Fault Detect
The system can notify you in the
event of a power supply failure. This
feature is available when three power
supply units are installed in the chas-
sis with one acting as a backup. If you
only have one or two power supply
units installed, you should disable
this (the default setting) with JPWF1
to prevent false alarms.
