INSTALLATION
THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND SHOULD
CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL CODES.
Mount the unit to a secure surface using #8 (3mm) hardware in four places. See the drawing at the
bottom of this page for mounting dimensions. Be sure to allow sufficient room for the required minimum
bend radius of the fiber cable used.
POWER SOURCE
THIS PRODUCT SHALL BE POWERED BY A LISTED CLASS 2 POWER SUPPLY ONLY.
This unit requires a +12VDC power source with a current rating of 1.25 amps for proper operation. The
DC input is diode protected. In the USA and in Canada an American Fibertek PS-12D is supplied with
this unit. The negative side of the power input is directly connected to ground. ANSI/NFPA 70 Class 2
wiring is recommended.
POWER CONNECTION
Power is supplied to the unit via a two pin terminal connector on the right side of the unit. Follow the
label on unit for proper orientation of +12 volt dc and ground.
FIBER CONNECTION
The fiber optic connection is made via a ST connector located on the right side of the unit.
VIDEO OUTPUT CONNECTION
The video output connection is made via a BNC connector on the right side of the unit. The 75
Ω video
output can be looped through typical baseband video inputs of switchers, recorders and other
equipment as required. For proper operation, the output must be terminated with 75
Ω. For optimum
performance the video cables should be the shortest length of coax practical.
