Mounting the Switcher

Keep the switcher out of bright light to prevent interference with the IR signals from the IR 501 remote control.

Tabletop use

For tabletop use, affix a self-adhesive rubber foot to each corner of the bottom of the switcher.

Rack mounting the switcher

UL requirements

The following Underwriters Laboratories (UL) requirements pertain to the installation of the matrix switcher into a rack (figure 2-1).

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. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

2.Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

3.Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

4.Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits 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) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

Mounting instructions

All of the MAV Series AV switcher models are housed in rack-mountable, 1U-high, full-rack wide metal enclosures. The appropriate rack mounting kit is included with each switcher. Rack mount the switcher as follows:

1.

If feet were previously installed on the bottom of the switcher, remove them.

2.

Attach the rack mount brackets to the switcher with the eight #8 machine

 

screws provided (figure 2-1).

3.

Insert the switcher into the rack, aligning the holes in the mounting bracket

 

with those of the rack.

4.

Secure the switcher to the rack using the supplied machine screws.
