Operation Precautions
Observe these precautions when using the UPS.
WARNING:
To reduce the risk of personal injury from earth conductor
leakage currents:
■
Do not operate a UPS that is disconnected from the utility power
source.
■
Disconnect protected devices from the UPS before disconnecting
the UPS from utility power.
■
Use the TEST/ALARM RESET button to test the batteries (rather
than unplugging the UPS). Refer to Initiating a Self-test, in this
chapter, for more information.
