Mounting the Switcher

UL guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the MTPX Plus into a rack.

1. Elevated operating ambient temperature — If the equipment 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 MTPX Plus 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).

Mounting instructions

The MTPX Plus switchers are housed in a rack-mountable, 2U high (matrix sizes 1616 and smaller) or 3U high (matrix sizes 1632 and larger) metal enclosures with mounting flanges for standard 19" racks. If desired, rack mount the unit as follows:

1.	Insert the switcher into the rack, aligning the holes in the mounting ears with
	those in the rack (figure 2-1).
2.	Secure the switcher to the rack using the supplied bolts.

NExtron recommends that you allow 1U of rack space above and below the switcher for ventilation.
