Section III
Operation
3.1 General
This section contains safety considerations, UPS operational procedures, and an
overview of the monitoring panel and operating controls for the system. Prior to operation,
ensure that the UPS has been installed correctly as outlined in Section II of this manual.
Ensure that correct input/output phase rotation and battery polarities have been observed.
Failure to do so can result in damage to the UPS and/or injury to personnel. Operators
should be thoroughly familiar with the contents of this manual and with the location and
function of all system controls and indicators.
3.2 Safety Considerations
Safety considerations are divided into several areas which are discussed below. Refer
also to Section IV of this manual, Maintenance, for safety precautions to be taken whenever
operating or working on the UPS.
3.2.1
Cleanliness
Litter or trash of any sort should not be allowed to accumulate in or around the UPS.
Liquid spills or metal objects carelessly dropped or placed can cause shorts and damage to
the system as well as possible injury to personnel. Dirt and dust accumulating at the UPS air
inputs can impede air flow, thereby decreasing the cooling effectiveness of the blowers and
possibly resulting in an overtemperature shutdown of the system.
3.2.2
Fire
In order to minimize the possibility of a fire and to reduce the extent of any damage
resulting from such an incident, the walls, ceiling and floor of the UPS room should be
constructed of noncombustible materials. A portable carbon dioxide extinguisher should be
located in the UPS room. Personnel involved in operating and/or maintaining the UPS
should be familiar with Class C hazard fires.
