3.3 Testing the Unit
The self test confirms the unit can switch from line power to backup battery power and back
without interrupting power to the loads. It takes about one minute to run.
Before starting:
• For the CFR 5000RM, the external battery pack must be connected.
• The battery circuit breaker must be on.
• The control panel’s Line Present LED must be on.
Procedure:
1
Press the Manual Start button down for 5
seconds.
During the test, the Test, Line Present and
Line Failure LEDs are on for about one
minute.
2
If a fault is found, the unit defaults to Line
Present operation without interrupting the
output. The Service LED turns on. Do
troubleshooting (Sections 3.4, 5.2).
TIP: The unit cannot provide backup
battery power when the Service LED is
on.
