Safety Precautions - Liebert Series 600T Installation Manual

1. SAFETY PRECAUTIONS

Read this manual thoroughly, paying special
attention to the sections that apply to you, before
working with the UPS. Retain this manual for
use by installing personnel.
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 from puddles of water, excess
moisture, or debris.
Special safety precautions are required for
procedures involving handling, installation, and
maintenance of the UPS system or 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 and 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 designated 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 potentials may exist at the capacitor banks
and at the batteries.
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).
Unless all power is removed from the equipment,
one person should never work alone. A second
person should be standing by to assist and
summon help in case an accident should occur.
Four types of messages are used throughout the
manual to stress important text. Carefully read the
text below each Danger, Warning, Caution, and
Note and use professional skills and prudent care
