Environmental Considerations

1.3.1

Room

The Dual-Lite TRX MBC is intended for indoor installation and should be located in a cool, dry, clean-

air environment with adequate ventilation to keep the ambient temperature within the specified

operating range (see

3.0 - Specifications

All models of the Dual-Lite TRX MBC are convection-cooled. To permit air to enter and exit and

prevent overheating or malfunctioning, do not cover the ventilation openings.
When bottom entry is used, the conduit plate can be removed and punched and replaced. The bottom

conduit plate must be replaced for proper airflow. If necessary to cool the room, install a system of

room extractor fans.

1.3.2

Storage

Should the equipment not be installed immediately, it must be stored in a room for protection against

excessive humidity and or heat sources (see

Table 6

1.4

Positioning

The cabinet is structurally designed to handle lifting from the base.
Access to the power terminals, auxiliary terminals blocks and power switches is from the top and

sides.
The top and side removable panels are secured to the chassis by screws. The side panel can be

removed for access to the power connections bars, auxiliary terminal blocks and power isolators.

1.4.1

Moving the Cabinets

The route to be travelled between the point of arrival and the unit’s position must be planned to make

sure that all passages are wide enough for the unit and that floors are capable of supporting its

weight (for instance, check that doorways, lifts, ramps, etc. are adequate and that there are no

impassable corners or changes in the level of corridors).
Ensure that the cabinet weight is within the designated surface weight loading (kg/cm

) of any

handling equipment. See

Table 8

for the weight of the Dual-Lite TRX MBC 200mm, 300mm, 600mm,

and 800mm models.

Tables 7

through

provide detailed dimension and weight information for the

Dual-Lite TRX UPS and Dual-Lite TRX MBC when they are bolted together and shipped as a system.
Ensure that any lifting equipment used in moving the cabinet has sufficient lifting capacity.
The Dual-Lite TRX MBC can be handled by means of a fork lift or similar equipment. For operations

with a fork lift, refer to installation drawings in

2.0 - Installation Drawings

Because the weight distribution in the cabinet is uneven, use extreme care during handling and

transporting.
When moving the unit by forklift, care must be taken to protect the panels. Do not exceed a 15-degree

tilt with the forklift.
Handling the unit with straps is not authorized.

NOTE

The Dual-Lite TRX MBC is suitable for mounting only on concrete and other noncombustible

surfaces.

WARNING

Risk of moving heavy units and tipping hazard. Can cause equipment damage, injury and

death.
Exercise extreme care when handling cabinets to avoid equipment damage or injury to

personnel. The Dual-Lite TRX MBC’s weight ranges from 198 to 700 lb. (89.8 to 317.5 kg).
