AVERTISSEMENT
Risque de décharge électrique due à un courant de fuite élevé pouvant causer des blessures, des
dommages matériels et même la mort.
IL EST PRIMORDIAL D'ASSURER UNE CONNEXION DE TERRE AVANT DE BRANCHER
L'ALIMENTATION D'ENTRÉE. La fuite à la terre est supérieure à 3,5 mA et inférieure à 1 000 mA.
Vous devez tenir compte des fuites de courant transitoires et permanentes à la terre, susceptibles de se
produire au démarrage de l'équipement, lors de la sélection des dispositifs DDFT instantanés.
Vous devez sélectionner des disjoncteurs différentiels de fuite à la terre (DDFT) sensibles aux impulsions
unidirectionnelles c.c. (classe A) et insensibles aux impulsions de courant transitoires.
Notez également que les courants de fuite à la terre de la charge seront acheminés par ce dispositif
DDFT.
Cet équipement doit être mis à la terre conformément au code national de l'électricité.
WARNING
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 the 10-40kVA 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.
