receiver.
Rack mounting the transmitter
UL requirements
The following Underwriters Laboratories (UL) requirements pertain to the
installation of the transmitter into a rack (figure 2-1).
1. Elevated operating ambient temperature — If 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 transmitter 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 a rack so that the amount of air
flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
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. Appropriate consideration of equipment
nameplate ratings should be used 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 (e.g. use of power strips).
Mounting instructions
If desired, rack mount the transmitter as follows:
1. Remove the rubber feet from the bottom of the transmitter.
2. Attach the 992546-2 rack mounting ears to the transmitter with the six
provided #8 machine screws (figure 2-1).
