ATTENTION:
•
Power supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply and the unit. The ridges
on the side of the cord (see
on the previous page) identify the power cord negative lead.
•
La polarité de la source d’alimentation est primordiale. Une polarité incorrecte pourrait endommager la source
d’alimentation et l’unité. Les stries sur le côté du cordon (voir
sur la page 2) permettent de repérer le pôle
négatif du cordon d’alimentation.
To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.
Mounting the Equalizer
ATTENTION:
•
I
nstallation and service must be performed by authorized personnel only.
•
L’installation et l’entretien doivent être effectués par le personnel autorisé uniquement.
The 1-inch high, eighth-rack width 12G HD-SDI 101 cable equalizer can be placed on a table, mounted in a rack, or mounted
under a desk or table.
Tabletop Use
Affix the included rubber feet to the bottom of the unit and place it in any convenient location.
Mounting Kits
Mount the unit using any optional compatible mounting kit listed on the 12G HD-SDI 101 product page at
accordance with the directions included with the kit. For rack mounting, see “UL rack-mounting guidelines” below.
UL rack-mounting guidelines
The following Underwriters Laboratories (UL) requirements pertain to the installation of the unit into a rack.
•
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 = +122 °F, +50 °C) specified by Extron.
•
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.
•
Mechanical loading
— Mounting of the equipment in the rack should be such that a hazardous condition is not achieved
due to uneven mechanical loading.
•
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.
•
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 use of power strips).
Troubleshooting
If no image appears:
•
Ensure that all devices are plugged in and powered on. The equalizer is receiving power if its power LED is lit.
•
Ensure an active input is applied to the equalizer.
•
Ensure that the proper signal format is supplied.
•
Check the cabling and make corrections as necessary.
•
Call the Extron S3 Sales & Technical Support Hotline if necessary. See the Extron
for the Extron office nearest you.
