Important Safeguards - Channel Master 9521A Owner's Manual

Your antenna rotator unit, consisting of a control and a drive, has been engineered and manufactured
to assure your personal safety, but improper installation or abuse of this unit, or the antenna connected
to it, can result in potential electrical shock or fire hazards. In order not to defeat the safeguards
incorporated in this unit, observe the following basic rules for its installation, use and servicing.
1. An outside antenna system should not be located in the vicinity of overhead power lines or other
electric light or power circuits, or where it can fall into such power lines or circuits. When installing
an outside antenna system, extreme care should be taken to keep from touching such power lines
or circuits as contact with them might be fatal.
2. If the drive unit is installed on an outdoor antenna, be sure the antenna system is grounded so as
to provide some protection against voltage surges and built-up static charges. Section 810 of the
National Electrical Code, ANSI/NFPA70, or CSA C22.1 Sections 10, 16, and 54, of the Canadian
Electrical Code, provides information with respect to proper grounding of the mast and supporting
structure, grounding of the antenna lead-in wire and drive-unit to control-unit interconnecting cables
to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit,
connection to grounding electrodes, and requirements for the grounding electrode. See separate
enclosed grounding code on page 26.
3. Your control is provided with ventilation openings to allow heat generated during operation to be
released, If these openings are blocked, heat build-up can cause failure of the control and external
damage. Therefore:
• Never block the ventilation slots by placing it on a bed, sofa, rug, etc.
• Never place in a "built-in" enclosure unless proper ventilation is provided;
• Never cover the openings with cloth or other material;
• Never place near or over radiators, heat registers, amplifiers, or other heat sources.
4. Your control may be equipped with a polarized AC line plug (one blade of the plug is wider than
the other). This safety feature allows the plug to fit into the power outlet only one way. Should you
be unable to insert the plug fully into the outlet, try reversing the plug. Should it still fail to fit,
contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the
polarized plug.
5. Operate the control only from an A.C. power source as indicated on the bottom of the control.
Do not use D.C.
6. Overloaded AC outlets and extension cords are dangerous, and so are frayed power cords and
broken plugs. They may result in a shock or fire hazard. Unplug the control and call your service
technician for replacement.
7. Do not allow anything to rest on or roll over the power cord, and do not place the control where
power cord is subject to traffic or abuse. Pay particular attention to the cord at the plug and the point
where it exists from the control unit. This may result in a shock or fire hazard.
