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 the panel indicators.
End-to-End testing of the UPS is accomplished by cycling the INPUT UPS/BY-
PASS 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 M359 has three double-pole power relays, one on the input, one on the
output and a third relay that bypasses the UPS section.
The front panel switches allow the user to control these three power relays.
Connector J4 on the back panel, allows the controlling of the M359 by a
remote 28Vdc/0.25A single pole, On/Off switch (Remote Power On/Off ) and a
28Vdc/0.25A, ON-ON, single pole switch (Remote UPS/By-Pass Select).
