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.
