Rack Mounting Procedure

The unit can be mounted on an optional Extron rack systems. Recommended mount kits for
the DA2 HD 4K device include: MBU 125 and RSB 123. Recommended mount kits for the
DA4 HD 4K or DA6 HD 4K devices include: MBU 123 or RSU 126, which are listed on the
Extron website (www.extron.com).To mount the unit on a rack shelf, follow the instructions
provided with the optional shelf kit.

Under-desk Mounting

Mount the unit under a desk or podium, using the optional Extron under-desk mounting kit,
UTS 100, listed on the Extron website (www.extron.com). Follow the instructions provided
with the 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.
Consider the equipment nameplate ratings 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).
