Rack mounting
UL guidelines for rack mounting
The following Underwriters Laboratories (UL) guidelines pertain to the installation
of an SW8/12 VGA Ars switcher unit onto a rack.
1 . Elevated operating ambient — If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be
greater than room ambient. Therefore, consider installing the equipment in an
environment compatible with the maximum ambient temperature specified
by Extron (Tma = +32 to +122 °F [0 to +50 °C]).
2 . Reduced air flow — Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
3 . Mechanical loading — Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
4 . Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits
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) — Reliable earthing of rack-mounted
equipment should be maintained. Particular attention should be given to
supply connections other than direct connections to the branch circuit (such as
the use of power strips).
