tabletop use
Each DMP 128 is supplied with rubber feet (not installed). For tabletop use, attach a
self-adhesive rubber foot to each corner of the bottom of the unit.
uL rack Mounting guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of
the DMP 128 in a rack.
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 unit 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 (such as the use of power strips).
