6.1
Normal (not first-time) start-up
This section describes the start-up procedures for the operator after a shutdown of the Centric. A
shutdown could occur due to battery exhaustion following an extended power outage, or due to a
manual shutdown by a technician prior to maintenance on the Centric.
After a normal
Centric
shutdown the main menu screen indicates a status of
"UPS OFF" and "No output":

.
Wait about 2 minutes for the
Centric
to start up.
While waiting, you can press the
status icon to see a display of the system status. The status
description at the top of the screen should become "UPS ON, Normal mode"
If instead of the status description being "UPS ON, Normal mode" it remains "UPS ON, Bypass
mode", there may be a problem with the rectifier voltage. You can see the input voltage readings on
the status screen. If the readings are not within acceptable limits, verify that the external circuit
breaker for the rectifier input voltage is ON, and that the rectifier input voltage is connected properly to
the UPS terminals.

.
Observe that the output voltage numbers and the bar graph now indicate the presence of the load (if
any) and the load's relative power consumption.
Centric start-up is now complete.
