Rack Mounting Procedure
The unit can be mounted on optional rack systems, including:
•
•
To mount the device on a rack shelf, follow the instructions provided with the shelf
accessories.
Under-desk Mounting
Mount the unit under a desk or podium using the optional Extron MBU 125 under-desk
mounting kit (part # 70-077-01) by following the instructions provided with the MBU 125
kit.
Through-desk Mounting
Mount the unit through a desk or podium using the optional Extron MBD 129 through-desk
mounting kit (part # 70-077-02) following the instructions provided with the MBD 129 kit.
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.
Reduced air flow — Install the equipment in the rack so that the equipment gets
adequate air flow for safe operation.
Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
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 the equipment nameplate ratings should be used when
addressing this concern.
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).
