UL Rack Mounting Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the

BUC 202 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 BUC 202 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 (as an example, use of power strips).

Tabletop Mounting

To mount the unit on a desk or tabletop, set the unit on a tabletop.

Rack Rail and Under-Furniture Mounting

NOTE: To properly mount the BUC 202 on a rack rail or under furniture use the Extron

ZipClip 200 Mounting Clip.
