UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products

in a rack:
1

.

Elevated operating ambient temperature —

If the unit 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 equipment in an environment compatible with the maximum ambient

temperature (Tma: +113 °F, +45 °C) specified by Extron.

2

.

Reduced air flow —

Install the equipment in the rack so that the equipment gets adequate air flow for safe

operation.

3

.

Mechanical loading —

Mount the equipment in the rack so that uneven mechanical loading does not

create a hazardous condition.

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. Give appropriate consideration to

the equipment nameplate ratings 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 (such as the

use of power strips).
