PIP 422 and PIP 444 Picture-in-Picture Processors • Installation 2-2
Installation
Mounting the Processor
The PIP 422 and PIP 444 are housed in 1U high, 17.4" wide metal enclosures that
are rack- or desk-mountable.
The appropriate rack/desk mounting kit (#70-077-03)
is included with the processor. The processor may also be surface-mounted under
a table, desk, or podium, or on a wall, using an optional Extron 1U enclosure
under-desk mounting kit (#70-222-01).
UL requirements
The following Underwriters Laboratories (UL) requirements pertain to the
installation of the PIP into a rack (figure 2-1) or furniture (figure 2-3.
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. Therefore, consider
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
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 (e.g.
use of power strips.
Rack mounting
Rack mount the PIP as follows:
1 . Remove the feet from the underside of the PIP, if installed.
2 . Attach the supplied rack mounting brackets to the processor with the eight
provided #8 machine screws (figure 2-1).
