Mounting the Switcher
Four uninstalled rubber feet are included with the 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 switcher, see “Tabletop Pacement,” below.
Tabletop Placement
For tabletop placement, install the self-adhesive rubber feet/pads (provided) onto the four
corners of the bottom of the switcher.
Rack Mounting
UL guidelines
The following Underwriters Laboratories (UL) requirements pertain to the installation of the
switcher into a rack (see figure 2 on the next page).
•
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 switcher 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 (that is, use of power strips).
Mounting instructions
To rack mount the switcher, use two screws on each end of the switcher to attach the
switcher to the rack (see figure 2).
