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.
1. Connect the input power cord to the IEC-320-C14 input power connector on the UPS rear panel
(INTL model only).
2. Connect the UPS power cord to a grounded utility power outlet. When the UPS is plugged in, the
batteries begin to charge. Power to the output receptacles designated for surge and battery backup
is not available until the unit is powered up.
For more information about receptacle control, see "Power management software (on page 25)" .
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.
