Rack mounting
UL guidelines for rack mounting
The following Underwriters Laboratories (UL) guidelines are
relevant to the safe installation of these products in a rack:
1
. Elevated operating ambient temperature — If the unit
is installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore,
install the equipment in an environment compatible with
the maximum ambient temperature (Tma: +122 °F, +50 ° C)
specified by Extron.
2 . Reduced air flow — Install the equipment in the rack
so that the equipment gets adequate air flow for safe
operation.
3 . Mechanical loading — Mount the equipment in the rack
so that uneven mechanical loading does not create a
hazardous condition.
4 . Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Give appropriate consideration to the
equipment nameplate ratings when addressing this
concern.
5 . Reliable earthing (grounding) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (such as the use of power
strips).
Rack mounting procedure
1 . If feet were installed on the bottom of the interface, remove
them.
2 . Place the interface on one half of the 1U (one unit high,
19" wide) optional rack shelf (part #60-190-01). Align the
front of the interface with the front of the shelf, and align
the threaded holes on the bottom of the interface with the
holes in the rack shelf (figure 2-5).
