Battery Cabinet Precautions
The following warning applies to all battery cabinets supplied with UPS systems. Additional warn-
ings and cautions applicable to battery cabinets may be found in 3.0 - Battery Installation.
!
CAUTION
This equipment is fitted with RFI suppression filters.
Ground leakage current exceeds 3.5 mA and is less than 1000 mA.
Transient and steady-state ground leakage currents, which may occur when starting the
equipment, should be taken into account when selecting instantaneous residual current
circuit breakers (RCCBs) or residual current devices (RCDs).
RCCBs must be selected sensitive to DC unidirectional pulses (Class A) and insensitive to
transient current pulses.
Note also that the ground leakage currents of the load will be carried by this RCCB or RCD.

WARNING
Under typical operation and with all UPS doors closed, only normal safety precautions are
necessary. The area around the UPS system should be kept free of puddles of water, excess
moisture and debris.
Special safety precautions are required for procedures involving handling, installation and
maintenance of the UPS system and the battery. Observe all safety precautions in this
manual before handling or installing the UPS system. Observe all precautions in the
Operation and Maintenance Manual, before as well as during performance of all maintenance
procedures. Observe all battery safety precautions before working on or near the battery.
This equipment contains several circuits that are energized with high voltage. Only
test equipment designed for troubleshooting should be used. This is particularly true for
oscilloscopes. Always check with an AC and DC voltmeter to ensure safety before making
contact or using tools. Even when the power is turned Off, dangerously high electric charges
may exist within the UPS.
All power and control wiring should be installed by a qualified electrician. All power
and control wiring must comply with the NEC and applicable local codes.
ONLY qualified service personnel should perform maintenance on the UPS system.
When performing maintenance with any part of the equipment under power, service
personnel and test equipment should be standing on rubber mats. The service personnel
should wear insulating shoes for isolation from direct contact with the floor (earth ground).
Never work alone, even if all power is removed from the equipment. A second person should
be standing by to assist and summon help in case an accident should occur.

WARNING
Internal battery strapping must be verified by manufacturer prior to moving a battery cabinet
(after initial installation).
• Battery cabinets contain non-spillable batteries.
• Keep units upright.
• Do not stack.
• Do not tilt.
Failure to heed this warning could result in smoke, fire or electric hazard.
Call 1-800-LIEBERT before moving battery cabinets (after initial installation).
