Extron Electronics IN3254 User Guide - Manual (Page 7)

IN3254 • Introduction 1-3
Power LED — A green LED lights to verify that the DA is
receiving power.
Sync Level —
An internal sync level control provides precise
adjustment of the sync portion of the video with the sync signal.
Installation
The IN3254 can mounted in a convenient location using the
Extron universal 2U rack shelf (Extron part# 60-032-01).
1
. Turn all equipment off and ensure that the source device,
the DA, and the output devices have been disconnected
from the power source.
2 . Place or install the unit in the desired location.
3 . Connect the video signal source (input) device to the input
connectors.
4 . Connect the output devices to the output connectors.
5 . Apply power to the output device(s), the DA, and the
input device.
6 . Set the gain and sync as needed.
Rack mounting
UL requirements for rack mounting
The following Underwriters Laboratories (UL) requirements
pertain to the installation of an IN3254 DA 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 the
manufacturer [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.
