Rack mounting

UL rack mounting requirements

The following Underwriters Laboratories (UL) requirements pertain to the safe installation of the equipment in a rack.

1. Elevated operating ambient temperature — If the equipment 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 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 (e.g., use of power strips).

Rack mounting procedure

To mount the distribution amplifier on a 6" deep or 9.5" deep rack shelf,

1.	If rubber feet were previously attached to the bottom of
	the unit, remove them.
2.	Mount the unit on the rack shelf, using two 4-40 x 3/16"
	screws in opposite (diagonal) corners to secure it.
3.	Install blank panel(s) or other unit(s) on the rack shelf.
4.	Attach the rack shelf to the rack using the supplied bolts.
