Chapter 2 Preparing for Installation Safety Guidelines • To help prevent electric shock, plug the appliance and power cables into properly grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cord, use a three-wire cord with properly grounded plugs. • Observe extension cord and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cord or power strip does not exceed 80 percent of the extension cord or power strip ampere ratings limit. • Do not use appliance, or voltage converters, or kits sold for appliances with your product. • To help protect your appliance from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS). • Position cables and power cords carefully; route cables and the power cord and plug so that they cannot be stepped on or tripped over. Be sure that nothing rests on your appliance cables or power cord. • Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local or national wiring rules. Safety with Equipment The following guidelines will help ensure your safety and protect the equipment. However, this list does not include all potentially hazardous situations, so be alert. Warning Read the installation instructions before connecting the system to the power source. Statement 1004 • Always disconnect all power cords and interface cables before moving the appliance. • Never assume that power is disconnected from a circuit; always check. • Keep the appliance chassis area clear and dust-free before and after installation. • Keep tools and assembly components away from walk areas where you or others could trip over them. • Do not work alone if potentially hazardous conditions exist. • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. • Do not wear loose clothing that may get caught in the appliance chassis. • Wear safety glasses when working under conditions that may be hazardous to your eyes.
