UL/Safety Requirements

The Underwriters Laboratories (UL) requirements listed below pertain to the safe installation and operation of the switcher.

1.This unit is not to be connected to a centralized DC power source or used beyond its rated voltage range.

The Extron P/S 100 and other Extron power supplies may be used with the MLS.

2.Do not use the switcher near water.

To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

3.Clean the switcher only with a dry cloth.

4.Do not install the switcher near any heat source, such as a radiator, heat register, stove, or another apparatus (including amplifiers) that produces heat.

5.Unplug the switcher during lightning storms or when it will be unused for long periods.

6.This unit must be installed in accordance with the National Electrical Code.

Mounting the Switchers

The one rack unit high, quarter rack width switchers can be set on a table, or mounted on a rack shelf, mounted under a desk or tabletop, or mounted on a projector bracket.

Tabletop use

Each MLS switcher comes with rubber feet. For tabletop use, attach a self-adhesive rubber foot to each corner of the bottom of the unit.

Rack mounting

For optional rack mounting, do not install the rubber feet. Mount the MLS on a VersaTools™ 19" 1U Rack Shelf (Extron part #60-190-20) or a standard Universal 1U Rack Shelf (Extron part #60-190-01). On the standard rack shelf, the MLS mounts in one of four locations to the rear of the rack or in one of four locations to the front of the rack.

1.	If rubber feet were previously installed on the bottom of
	the MLS, remove them.
2.	Mount the MLS on the rack shelf, using two 4-40 x 1/8
	screws in opposite (diagonal) corners to secure the MLS
	switcher to the shelf.
