Series 7400 Single Phase 1+N UPS

1.3 Safety Precautions

1.3.1General

1.3.2Batteries

1.3.3Test Equipment

1.3.4Personnel

In common with other types of high power equipment, dangerous voltages are present within the UPS and battery enclosure. The risk of contact with these voltages is minimised as the live component parts are housed behind a hinged, lockable door. Further internal safety screens make the equipment protected to IP20 standards. No risk exists to any personnel when operating the equipment in the normal manner, following the recommended operating procedures.

All equipment maintenance and servicing procedures involve internal access and should be carried only by trained personnel.

Battery manufacturers supply details of the necessary precautions to be observed when working on, or in the vicinity of, a large bank of battery cells. These precautions should be followed implicitly at all times.

Particular attention should be paid to the recommendations concerning local environmental conditions and the provision of protective clothing, first aid and fire-fighting facilities.

When the battery is charge it is earth-referenced about it is mid- point -e.g. if the battery is being charged at 432V the battery extremities will be at +216V and - 216V with respect to neutral (earth). When using mains-powered test equipment such as oscilloscopes in the UPS high voltage area, always use a differential mode of operation to avoid the need to disconnect the oscilloscope frame earth.

When working inside the UPS (trained personnel only) it is recommended that protection be worn to prevent eye damage, should an electrical arc be struck by mishandling or severe electrical fault.

Some of the power components are very heavy. If their removal is necessary ensure that sufficient manpower is available, otherwise use adequate mechanical handling equipment.

When working in the general area of the UPS where high voltages are present, a second person should be standing-by to assist and summon help in case of accident.
