14 Protective attachment plug-The product is equipped with an attachment plug having overload protection. This is a safety feature. See the instruction manual for replacement or resetting of protective device. If replacement of the plug is required, be sure the service technician has used a replacement plug specified by the manufacturer that has the same overload protection as the original plug. 15 If an outside antenna or cable system is connected to your product, make sure that the antenna or cable system is grounded to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. 7 6 5 4 3 1 2 Reference Grounding component 1 Electric service equipment 2 Power service grounding electrode system (NEC Art 250, Part H) 3 Ground clamp 4 Grounding conductors (NEC Section 810-21) 5 Antenna discharge unit (NEC Section 810-20) 6 Ground clamp 7 Antenna lead-in wire • Use No. 10AWG (5.3 mm2) copper, No. 8AWG (8.4 mm2) aluminum, No. 17AWG (1.0 mm2) copper-clad steel or bronze wire, or larger, as a ground wire. • Secure the antenna lead-in and ground wires to the house with stand-off insulators spaced from 4-6 feet (1.22-1.83 meter) apart. • Mount the antenna discharge unit as close as possible to where the lead-in enters the house. • Use a jumper wire not smaller than No. 6AWG (13.3 mm2) copper, or the equivalent, when a separate antenna-grounding electrode is used. See ANSI/NFPA70. 16 Lightning-Unplug this product during lightning storms or when unused for long periods of time. For added protection for this product equipment during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage to the equipment due to lightning and power-line surges. 17 Power lines-Do not locate an outside antenna system 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. Take extreme care when installing an outside antenna system to keep from touching such power lines or circuits as contact with them might be fatal. 18 Overloading-Do not overload wall outlets, extension cords, or convenience receptacles on other equipment as this can result in a risk of fire or electric shock. 19 Entering of objects and liquids-Never insert an object into the product through vents or openings. High voltage flows in the product, and inserting an object can cause electric shock and/or short internal parts. For the same reason, do not spill water or liquid on the product. 20 Servicing-Refer all servicing to qualified service personnel. Servicing is required when the product has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the product, the product has been exposed to rain or moisture, does not operate normally, or has been dropped. 21 Damage requiring service-If any of the following conditions occurs, unplug the power cord from the AC outlet, and request a qualified service person to perform repairs. • When the power cord or plug is damaged. • When a liquid is spilled on the product or when objects have fallen into the product. • When the product has been exposed to rain or water. • When the product does not operate properly as described in the operating instructions. Do not touch the controls other than those described in the operating instructions. Improper adjustment of controls not described in the instructions can cause damage, which often requires extensive adjustment work by a qualified technician. • If the product has been dropped or the cabinet has been damaged in any way. • When the product displays an abnormal condition or exhibits a distinct change in performance. Any noticeable abnormality in the product indicates that the product needs servicing. 4 www.insignia-products.com
