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.
b. Plug the output module into the special UPS output receptacle, located on the rear of the UPS.
