USP 507 • Installation
Mounting the USP 507
If the USP 507 is to be rack mounted, it is important to mount it before cabling it.
Four rubber feet are included with the unit. Install the feet only if the unit is to be
mounted on a tabletop (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 device.
UL guidelines for rack mounted devices
The following Underwriters Laboratories (UL) guidelines pertain to the safe
installation of the USP 507 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 device 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 (such as use of power strips).
Rack mounting
To rack mount the USP 507, insert screws under each opposite corner of the unit
and secure it to the rack (see figure 2-1).
