Power Cables
The Dual-Lite TRX MBC requires both power and control cabling once it has been mechanically
installed. All control cables must be separate from the power cables. Run control cables in metal
conduits or metal ducts that are electrically bonded to the cabinets they are connected to.
The cable design must comply with the voltages and currents provided in
follow local wiring practices and take into consideration the environmental conditions (temperature
and physical support media).
For cable entry locations, refer to
.
The following are guidelines only and are superseded by local regulations and codes of practice where
applicable:
• Take special care when determining the size of the neutral cable (grounded conductor), because
current circulating on the neutral cable may be greater than nominal current in the case of
nonlinear loads.
• The grounding conductor should be sized according to local or NEC codes, cable lengths, type of
protection, etc. The grounding cable connecting the UPS to the main ground system must follow
the most direct route possible.
• Consider using smaller, paralleled cables for heavy currents as a way of easing installation.

WARNING
Risk of electric shock. Can cause equipment damage, injury and death.
Before cabling up the cabinet, ensure that you are aware of the location and operation of the
external isolators that connect the input/bypass supply.
Check that these supplies are electrically isolated, and post any necessary warning signs to
prevent their inadvertent operation.

AVERTISSEMENT
Risque de décharge électrique pouvant entraîner des dommages matériels, des blessures et
même la mort.
Avant de procéder au câblage de l’armoire, assurez-vous que vous êtes au courant de
l’emplacement et du fonctionnement des isolateurs externes qui raccordent l’alimentation
d’entrée ou de dérivation.
Vérifiez que ces raccords sont isolés électriquement et installez tous les panneaux
d’avertissement nécessaires pour empêcher leur utilisation accidentelle.
