Automatic System Test

The UPS performs an automatic system test every seven days to test the memory, batteries, and inverter. During the system test, the BATTERY POWER and READY indicators Flash. For the results of the last system test, you can display parameter 26 (see page 35).

Logic Test

First, the UPS checks its memory. If it finds a problem, the UPS sounds alarm O, Memory Check (– – –). See “Alarms” on page 59.

Inverter Test

The inverter converts DC battery power into the AC power your equipment uses. During the inverter test, the UPS pulses its inverter to see if it delivers the proper amount of current. If not, the UPS sounds alarm N, Check Inverter (– :). See “Alarms” on page 59.

Although it is testing the inverter, the UPS is not in Inverter On mode. The UPS continues to condition input power and is ready to provide battery power if there is a power outage. The BATTERY POWER indicator flashes during this part of the test.

NOTE FE models with serial numbers 25000 and greater do not perform an individual inverter test.

Battery Test

The UPS also checks its batteries to verify that they can support your equipment for the minimum specified runtime. If not, the UPS sounds alarm M, Check Battery (– –). See “Alarms” on page 59. The READY indicator flashes during this part of the test.
