Connecting the UPS to utility power
WARNING:
To prevent injury from electric shock or damage to the equipment:
•
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.
Connect the UPS to a grounded utility power outlet. When the UPS is plugged in, it 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.
•
Evenly distribute connected devices to both circuit breakers. See "UPS output specifications (on page
44
)" for the maximum current rating for each receptacle.
After verifying that the UPS will not overload:
1.
Turn on the circuit breakers for load segments 1 and 2.
NOTE:
The circuit breaker for load segment 1 protects the C19 and C13 outlets but not the large output
receptacle.
