Emerson 115-208 Manuel D’Utilisation

  

Risk of improper ground connection. Can cause equipment damage.
Ground connection is essential before connecting the input supply. This equipment must be 

grounded in accordance with local electrical codes. Maximum load must not exceed that 

shown on the UPS rating label.

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. These limits provide reasonable protection against harmful interference in a 

commercial environment. This unit generates, uses and radiates radio frequency energy and, 

if not installed and used in accordance with this instruction manual, may cause harmful 

interference to radio communications. This unit is not designed for use in a residential area. 

Operation of this unit in a residential area may cause harmful interference that the user is 

solely responsible for correcting.

Risk of electric shock from high leakage current. Can cause injury, property damage and 

death.
EARTH CONNECTION IS ESSENTIAL BEFORE CONNECTING THE INPUT SUPPLY.
Earth leakage current exceeds 3.5 mA and is less than 1000 mA.
Transient and steady-state earth leakage currents, which may occur when starting the 

equipment, should be taken into account when selecting instantaneous RCCB or RCD devices.
Residual Current Circuit Breakers (RCCBs) must be selected sensitive to DC unidirectional 

pulses (Class A) and insensitive to transient current pulses.
Note also that the earth leakage currents of the load will be carried by this RCCB or RCD.
This equipment must be earthed in accordance with the local electrical code of practice.

Risk of electric shock. Can cause injury, property damage 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 internal batteries (internal batteries accommodated 

by 45kVA frame only). Observe all safety precautions in this manual before handling or 

installing the UPS system as well as during 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 AC and DC voltmeters 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.
