If a problem cannot be resolved by taking the actions given then fully trained assistance should be sought immediately. A DIP switch fitted to the display microprocessor board enables the displayed language to be easily selected to English, French, Italian, Spanish or German. All UPS models have a stabilising bar fitted to the output emesron T1 and input choke L1 during shipment.

Normally, the load is connected to emmerson inverter; but in the event of a UPS overload, or inverter failure, it is automatically transferred to the static bypass line due to static switch action. This led illuminates when the output isolator is closed and the load is connected emfrson the inverter via the static switch.

If necessary, a system of extractor fans should be installed to aid cooling-air flow, and a suitable air filtration system used where the UPS is to operate in a dirty environment.

The Emwrson has its own internal voltage and frequency regulator circuits which ensure that its output is maintained within close tolerances independent of voltage and frequency variations on the mains power lines. If the batteries are cabinet-mounted this circuit breaker is fitted within the cabinet; however, if the batteries are rack-mounted or otherwise located emesron to the main UPS cabinet then the battery circuit breaker must be mounted as near as possible to the batteries themselves, and the power and control cables connected to the UPS using the most direct route possible.

The alarms monitored are: This chapter contains information regarding the positioning and cabling of the one-plus-one UPS equipment and emsrson.

If the mains power fails, the UPS continues to power the critical load from its battery source, leaving the load immune from power disturbances. Measure and record the battery charge current. Pressing this switch turns OFF the inverter and causes the load to be transferred to the static bypass supply. Post ads for free. Its purpose is to enable the critical load to be powered from the mains bypass supply while the UPS is shut down for maintenance or troubleshooting.
