Switching on the UPS battery circuit breaker 
 
When the UPS is plugged in and the battery circuit breaker is on, the UPS automatically enters Standby mode 
and begins charging the batteries. 
 
Connecting devices to the UPS 
 
 
CAUTION: Do not plug laser printers into the UPS output receptacles. The instantaneous current 
drawn by this type of printer can overload the UPS. 
 
Before connecting devices, verify that the UPS will not overload by checking that the ratings of the devices do 
not exceed the UPS capacity. If the equipment rating is listed in amps, multiply the number of amps by the 
nominal AC source to determine the VA. 
To provide additional receptacles:  
•  For the 8kVA models—Plug a PDU into the UPS output receptacle at the end of the power cord.   
•  For the 12kVA models— 
a.  Install the included output module on the rear rack frame.
