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. Observe all safety precautions in this manual before handling or installing the UPS 
system as well as during all maintenance procedures.
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.

AVERTISSEMENT

Risque de décharge électrique pouvant causer des blessures, des dommages matériels et même la mort.
Les précautions de sécurité habituelles suffisent lorsque le système ASC est en mode de fonctionnement 
normal et que toutes les portes sont fermées. La zone entourant le système ASC doit être exempte de 
flaques d’eau, d’humidité excessive et de débris.
Des précautions de sécurité spéciales sont requises pour les procédures associées à la manutention, à 
l’installation et à l’entretien du système ASC. Observez toutes les précautions de sécurité décrites dans le 
présent manuel avant de manipuler ou d’installer le système ASC, ainsi que pendant toutes les 
procédures d’entretien.
Cet équipement comporte plusieurs circuits à haute tension. Seuls des équipements d’essai conçus pour 
le dépannage doivent être utilisés. Cette mise en garde couvre notamment les oscilloscopes. Utilisez 
toujours des voltmètres c.a. et c.c. pour vérifier les tensions avant d’établir un contact ou d’utiliser des 
outils. Des tensions dangereusement élevées peuvent demeurer dans le système ASC même une fois 
l’alimentation coupée.
Tous les câbles d’alimentation et de contrôle doivent être installés par un électricien qualifié. Tous les 
câbles d’alimentation et de contrôle doivent être conformes au Code national de l’électricité des États-
Unis (NEC) et celui du Canada, ainsi qu’aux codes locaux en vigueur.
L’entretien du système ASC ne doit être confié qu’à des professionnels qualifiés.
Les responsables de l’entretien et l’équipement d’essai doivent reposer sur des tapis de caoutchouc lors 
de toute intervention sur une pièce d’équipement sous tension. Les responsables de l’entretien doivent 
porter des chaussures isolantes pour prévenir tout contact direct avec le plancher.
Ne travaillez jamais seul, même si toute l’alimentation d’entrée est coupée de l’équipement. Une seconde 
personne devrait toujours être présente pour porter assistance ou chercher de l’aide en cas d’accident.

WARNING

Failure to follow adequate grounding procedures can result in electric shock hazard to personnel, or the 
risk of fire, should a ground fault occur.

All operations described in this section must be performed by properly trained and qualified electricians 
or technical personnel. If any difficulties are encountered, contact Vertiv

. See the back page of this 

manual for contact information.
