Installation
Mounting the Switcher
Four uninstalled rubber feet are included with the seamless switcher. If you
are going to rack mount the switcher, mount it before you cable it (see "Rack
mounting", below), and do not install the rubber feet. If you are not rack mounting
the seamless switcher, see "Tabletop placement", below.
Tabletop placement
For tabletop placement, install the self-adhesive rubber feet/pads (provided) onto
the four corners of the bottom of the seamless switcher.

2-2 ISS 506 Integration Seamless Switcher • Installation
Elevated operating ambient temperature — If the equipment 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 ISS in an environment compatible with the maximum ambient
temperature (Tma = +122 °F, +50 °C) specified by Extron.
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.
Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
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.
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).
