3.3 Testing the Unit
The self test confirms the unit can switch from line to backup battery power and back without
interrupting power to the loads. It takes about one minute to run.
Before starting:
• 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.
