3.CONNECT THE EQUIPMENT TO THE UPS AND CONNECT THE UPS TO THE AC POWER SUPPLY

1.On the back panel, plug the female end of the power cord into the receptacle. Then plug the male end into a two-pole, three-wire, grounding receptacle. Avoid using extension cords and adapter plugs.

2.Connect the equipment to the UPS using the power cords provided with the equipment.

3.Turn on all connected equipment. To use the UPS as a master ON/OFF switch, be sure all con- nected equipment is switched on. The equipment will not be powered until the UPS is turned on.

4.TURN ON THE UPS

Make sure the battery is connected before turning on the UPS! Press the button on the front panel to power up your UPS. This will power up connected equipment if that equipment is turned on.

The UPS charges the batteries when it is connected to utility power. Do not expect full run time during this initial charge period. Time depends on number and type of batter- ies.

The unit performs a self-test automatically when turned on and every two weeks thereafter (by de- fault). Refer to the User Configurable Items section of this manual, below, for details on changing the default interval.

To turn on the UPS when no utility power is present, see the Cold Start function in the Operations section of this manual.
