4.0 Installation

4.5 Plug loads into UPS

Plug all loads to be protected into the UPS. Do not exceed the UPS's capacity as given

in section 9.0. Once switched on, the UPS will monitor and display the magnitude of the

applied load.

Note: Do not plug laser printers into this UPS. Laser printers

draw a considerable amount of power. This will reduce the

available backup time and in some cases will cause the UPS to

signal an overload.

4.6 Check Site Wiring Fault indicator - 100, 120 Vac versions

Once loads are connected to the UPS and the UPS is turned on, the Site Wiring Fault

indicator at the UPS's rear panel should be checked. It will illuminate when the UPS is

plugged into an improperly wired wall outlet. Wiring faults detected include missing

ground, hot-neutral polarity reversal and overloaded neutral

circuit.

Note: If the UPS indicates a site wiring fault, a qualified electri-

cian should be summoned to correct the building wiring.

4.7 Switch on load equipment

If load equipment switches are left on, the UPS's I/Test pushbutton can be used as master

system on/off switch.

4.8 Switch on the UPS

The UPS and your loads will become energized when the I/Test

pushbutton is held pressed for a second. Once powered, the UPS

will initiate a battery test. During the test, the UPS will operate the

load from power derived from the battery. This test function ensures

that the UPS is working properly and that its battery does not require

replacement. In the event the batteries are too weak to support the load during

the test, the UPS will immediately return to on-line operation (the load will not be

affected). The test is completed when the On Line indicator ceases to blink.

Note: If the red Load indicator is illuminated, the UPS is overloaded. Unplug equipment

that does not require backing up, such as a printer, and restart the UPS. If the Replace

Battery indicator illuminates, recharge the UPS overnight and retest.
