When test mode is invoked by pressing the push-button on the front panel,
the UPS performs battery impedance testing without interrupting the output
power (even if the battery fails) utilizing a proprietary time-sharing circuit.
The test results are displayed on panel indicators.
End-to-End testing of the UPS is accomplished by cycling the INPUT
ON/OFF switch on the front panel.
The UPS will beep when it operates on battery power or during over-
temperature condition. The alarm may be silenced by pressing the "Alarm
Off" push-button on the front panel.
The M110BA-1 has two double-pole contactors, one on the input and one on
the output.
The input ON/OFF contactor is controlled by the input ON/OFF switch
located on the front panel.
The Master ON/OFF switch, located on the front panel, shuts down the UPS
and opens both input and output contactors when in the OFF position.
When the two ON/OFF pins are opened the UPS will turn OFF and the
input and output contactors will open. When the two lines are shorted
together the front panel switches determine the status. (The UPS is supplied
with a mating connector and a jumper between the two ON/OFF pins).
