This manual contains important instructions that should be followed during installation of your
Series 610 UPS and batteries.
WARNING
!
Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to
personnel. The UPS module weight ranges from 1470 to 4755 lbs. (667 to 2157kg), including
input transformer. The battery cabinets weigh from 3050 to 5300 lbs. (1383 to 2404kg).
Locate center of gravity symbols
cabinet. Test lift and balance the cabinets before transporting. Maintain minimum tilt from
vertical at all times.
Slots at the base of the modules and battery cabinets are intended for forklift use. Base slots
will support the unit only if the forks are completely beneath the unit.
System Control Cabinets (SCCs) have holes intended for rigging bars or chains. Prevent
chains or cables from contacting cabinet by using spreader bar and adequate padding.
Follow all battery safety precautions when installing, charging or servicing batteries. In
addition to the hazard of electric shock, gas produced by batteries can be explosive and
sulfuric acid can cause severe burns.
In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or
those approved for use in fighting electrical fires.
Extreme caution is required when performing maintenance.
Be constantly aware that the UPS system contains high DC as well as AC voltages.
Check for voltage with both AC and DC voltmeters prior to making contact.
Read this manual thoroughly, paying special attention to the sections that apply to your installation,
before working with the UPS. Retain this manual for use by installing personnel.
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 potential electric
charges may exist at the capacitor banks and at the batteries.
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).
One person should 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.
