To keep a convective air flow between the cabinet and the equipment room,
ensure there are no obstructions on all sides of the cabinet.
The applince takes in air from the front panel and circulates the air through the
system. Fans discharge air from the rear of the appliance. Air flows from front to
rear. The optional bezel can be installed on the front panel without any reduction
in air movement.
Environmental checklist
The following table describes the environmental checklist that must be completed
before appliance installation.

Environmental considerations
Requirement
Item
The floor meets load-bearing requirements. Wiring troughs,
ladders, and holes are ready. All construction is complete.
Facility preparation
If the temperature in the room may exceed 35°C, install air
conditioners which can be restarted upon recovery from a power
failure. Do not let the air conditioner blow directly on the devices.
Air conditioning
If the relative humidity is greater than 70%, a dehumidifying
device must be installed. Examples of such devices include an
air conditioner that provides a dehumidification function or a
special-purpose dehumidifier. Water penetration, dripping, and
condensation must all be prevented in the equipment room.
Moisture proofing
If the temperature in the room is lower than the stated minimum
of 10°C, heating devices are required.
Heating
If the equipment room is located near a potential source of dust
or other particulate matter, a double aluminum alloy window
and an anti-theft fire door must be installed. The devices must
be separated from the door and a baffle must be used to prevent
dust pollution.
Dust proof
The equipment room must have a lightning protection device
such as lightning rod or lightning strip. The grounding of the
lightning protection device and the protective grounding of the
equipment room must share a grounding body.
Lightning strike protection
In addition, make sure that the following special requirements are met:
