! WARNING
Risk of electric shock. Can cause injury and death.
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 batteries. Observe all safety precautions in this manual before handling or installing the UPS system. Observe all precautions in this 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.
! CAUTION
This equipment is fitted with RFI suppression filters.
Ground leakage current exceeds 3.5 mA and is less than 30 mA.
Transient and
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.
NOTICE
Risk of improper improper electromagnetic shielding. Can cause radio communication interference.
This unit complies with the limits for a Class A digital device, pursuant to Part 15 Subpart J of the FCC rules.
