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)
specied by Extron.
2. Reduced air flow — Install the equipment in the rack
so that the equipment gets adequate air ow 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.
