UPS Startup
The Liebert APM must be fully installed and commissioned before startup, and external power
isolators must be closed. Once those general conditions are met, the UPS may be started.
! WARNING
Risk of electrical shock and arc flash. Can cause property damage, injury and death.
During this procedure the output terminals will become live.
If any load equipment is connected to the UPS output terminals, please check with the load
user and ascertain whether it is safe to apply power to the load. If the load is not ready to
receive power, then ensure that it is safely isolated from the UPS output terminals.

NOTE
For standardization, if the quantity of modules in system is less than 6, for example 45kVA
system, Emerson recommends setting the address bits of the modules as 1, 2, 3 respectively.
6. Close the external input circuit breaker and connect input power.
The LCD activates. The rectifier indicator flashes while the rectifier is starting. The rectifier
enters normal operation state, and after about 30 seconds, the rectifier indicator stops blinking
and is illuminated in a steady green. After initialization, the bypass static switch turns on. The
mimic LEDs appear as shown Table 28.
