UL guidelines for rack mounting
The following Underwriters Laboratories (UL) guidelines pertain to the installation of
an HDMI 201 unit onto 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 shelf mounting instructions
On the 6-inch and 9.5-inch rack shelves, the transmitter or receiver unit can be mounted
in the front or the rear of the rack.
1. Remove the feet from the bottom of the transmitter or receiver unit if installed.
2. Mount the transmitter or receiver unit on the rack shelf, using two 4-40 x 3/16-inch
screws in opposite (diagonal) corners to secure it to the shelf (
figure 2 ).
(2) 4-40 x 3/16"
Screws
Use 2 mounting holes on
opposite corners.
