2-6 Compaq Pro UPS 500 Operation and Reference Guide

Verifying a Safe UPS Load

Before connecting any devices, verify that the Battery-and-Surge-Protected
receptacles of the UPS will not overload. The cumulative VA rating of all
devices (the load) to be connected to the Battery-and-Surge-Protected
receptacles cannot exceed the 500VA rating.
Use the following conversion equation:
For devices listing the power in amperes:
I
Volts x Amps = VA per device
For devices listing the power in watts:
I
Watts x 1.35 = VA per device
NOTE: Verifying a safe load does not include the devices connected to the
Surge-Protected receptacle(s).
