Single or '1+N' UPS System Liebert Hipulse E Installation Manual
Page vi (07/04)
General
As 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 minimized 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 out only by
trained personnel.
Batteries
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.
WARNING
Follow these instructions scrupulously:
The Liebert Hipulse E is designed exclusively for indoor use. Protect the unit from excessive condensation and
install it in a place free of flammable liquids, gases and corrosive substances.
Electrical installation must be performed by a qualified electrician.
Personnel working with the equipment described in this manual must be thoroughly familiar with the product.
Before making connections inside the unit, make sure that all incoming power sources are de-energised and
insulated.
When the incoming power source is active, the unit contains a dangerous level of voltage, even when it has
“maintenance bypass” status.
To insulate the unit, turn it off and insulate all incoming power sources and auxiliary power sources.
