2-8 Compaq 3000 Series UPS Operation and Reference Guide
Connecting the UPS to Utility Power
Connect the UPS to a grounded utility power outlet.
WARNING: To reduce the risk of electric shock or damage to the equipment, take these precautions:
■Plug the input line cord into a grounded (earthed) electrical outlet that is installed near the equipment and is easily accessible.
■Do not disable the grounding plug on the input line cord. The grounding plug is an important safety feature.
■Do not use extension cords.
Connecting Devices to the UPS
Before connecting devices, verify that the UPS will not overload by making sure that the total VA rating of the devices (the load) does not exceed the VA rating of the UPS.
Volts x Amps = VA per device
If the devices list the power in Watts, use the following conversion equation:
Watts x 1.35 = VA
VA/1000 = KVA
You may use RackBuilder Pro as an alternate conversion tool. RackBuilder
Pro may also be obtained from the Compaq website:

After verifying that the UPS will not overload, connect the power cords from the devices to the appropriate output receptacles of the UPS.
WARNING: To reduce the risk of electric shock, the combined earth conductor leakage current from all connected devices must not exceed 3.5 mA.
CAUTION: Do not plug laser printers into the UPS. The instantaneous current drawn by this type of printer may overload the UPS.
IMPORTANT: To provide additional receptacles, plug a Compaq Power Distribution Unit (PDU) into the high current receptacle associated with load segments 1, 2, or 3. To connect the devices to the PDU, use
