Extron Electronics DMP 64 User Guide - Manual (Page 145)

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.
