Hardware Features and Installation
Optional rack shelves and an assortment of mounting kits (back of the rack,
furniture, and projector pole mount) are available for use with the IPL. See
appendix A for part numbers of these accessories, and read the instructions that
come with the rack shelf or mounting kit for installation procedures.
The IPL 250 includes rubber feet so it can be set on a table. If you are going to
mount the unit to a rack, rack shelf, furniture, or pole, and these feet were attached
to the enclosure, remove the feet before mounting.
Rack mounting
UL rack mounting guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe
installation of the IPL 250 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 IPL 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 (e.g. use of power strips).
Rack mounting with a rack shelf
