B. Controls
The UPS shall contain a front panel mounted main On/Off switch. The UPS shall also contain microcontroller-
based monitoring and controls for reliable operation.
C. DIP Switch Operation
The UPS shall contain four user-selectable DIP switches that will allow the following:
Switch 1
50/60Hz selection
Switch 2
Enable or Disable High Line Alarm
Switch 3
Transfer to Battery Setpoint
Switch 4
Enable/Disable line to neutral reversal alarm
D. Alarm Silence
On 400 and 600 VA models, the alarm silence switch shall be used to silence the On Battery alarm only,
whether utility power is present or not, except when operating in a low battery condition.
2.2.3
Automatic self diagnostic tests
The UPS shall perform three (3) different automatic self-diagnostic tests as described below:
A. Automatic self-diagnostic test: Power ON
The UPS must qualify the utility line voltage before initiating start-up. Qualification of the utility shall consist of
verifying utility power is within start-up voltage range.
Once the utility power has been qualified and followed by the UPS being switched ON, the UPS shall perform
start-up tests, consisting of an electronics and battery test, prior to enabling output power from the inverter.
Should the UPS fail any start-up test, the output power shall not be enabled and fault signals (visual and
audible) shall be enunciated.
