PowerCage 1600 Enclosure • Installation
7
The PowerCage enclosure can be mounted in a standard equipment rack before or after
installing transmitter and receiver boards. To rack mount the enclosure, follow the UL
guidelines and refer to the diagram in the “
” section.
UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the
equipment in a rack.
1.
Elevated operating ambient — If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consider installing the equipment in an environment compatible with
the maximum ambient temperature specified by the manufacturer [Tma = +32 to +122 °F
(0 to +50 °C)].
2.
Reduced air flow — Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
3.
Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4.
Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might have
on overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
5.
Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should
be maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (such as the use of power strips).
Rack Mounting
CAUTION: Leave open space of at least 1U on the top, bottom, and
sides of the enclosure to allow adequate air circulation
and prevent overheating. Do not cover the vents or fans.
NOTE: Air flows through the enclosure from right
to left, as viewed from the front panel.
To rack mount the enclosure:
1.
Attach the mounting
brackets to the sides
of the enclosure, as
shown in figure 5.
The brackets can be
attached at either the
front or the back.
2.
Fasten the brackets
to the rack.
