Mounting the DMP 64

The 1U high, half rack width, 9.5 inch deep DMP 64 Digital Matrix Processor can be:

•Set on a table,

•Mounted on a rack shelf,

•Mounted under a desk or tabletop, or

•Mounted on a projector bracket.

Tabletop Use

The DMP 64 includes 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 64 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 can 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 (e.g. use of power strips).

Rack Mounting

For optional rack mounting, do not install the rubber feet. Mount the DMP 64 on a 19 inch Universal 1U or Basic rack shelf. Follow the instructions included with the rack mount kit to install the DMP 64.

Furniture Mounting

Furniture mount the DMP 64 using the optional mounting kit (Extron MBU 125, part number 70-077-01, under-desk, or Extron MBD 129, part number 70-077-02, through‑desk). Follow the instructions included with the mounting kit to install the DMP 64.

Table or Wall Mounting

The MBU 125 table or wall mounting brackets extend approximately 1/4 inch (6.4 mm) above the top surface of the enclosure. This design allows for an air space between the enclosure and the surface to which it is mounted. Follow the instructions included with the mounting kit to install the DMP 64.
