Mounting the Switcher

The MPS 112 and MPS 112CS are housed in 1U high, 17.4" wide metal enclosures that are rack- or desk-mountable. The MBD 149 1U through-desk and rack mounting kit (#70-077-03) is included with the switchers. The switchers may also be surface-mounted under a table, desk, or podium, or on a wall, using the optional Extron MBU 149 1U under-desk mounting kit (#70-222-01).

	provided #8 machine screws (figure 2-1).
2.	Insert the switcher into the rack, aligning the holes in the mounting bracket
	with those of the rack.
3.	Secure the switcher to the rack using the supplied machine screws.

UL rack mounting requirements

The following Underwriters Laboratories (UL) requirements pertain to the safe installation of the MPS 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 device 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.
