OPERATION AND ADJUSTMENT HOW TO CONNECT THE POWER CORD Use a Surge Suppressor Your treadmill, like other electronic equipment, can be damaged by sudden voltage changes in your home’'s power. Voltage surges, spikes, and noise interference can result from weather conditions or from other appliances being turned on or off. To decrease the risk of damaging the treadmill, always use a surge suppressor with the treadmill. To purchase a surge suppressor, see precaution 12 on page 3. Use only a surge suppressor that is UL 1449 listed as a transient voltage surge suppressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules. The surge suppressor must also be electrically rated for 120 volts AC and 15 amps. There must be a monitoring light on the surge suppressor to indicate whether it is functioning properly. Failure to use a properly functioning surge suppressor could result in damage to the control system of the treadmill and serious injury to users. nominal 120-volt circuit capable of carrying 15 or more amps. To avoid overloading the circuit, do not plug other electrical devices, except for lowpower devices such as cell phone chargers, into the surge suppressor or into an outlet on the same circuit. IMPORTANT: The treadmill is not compatible with GFCI-equipped outlets and may not be compatible with AFCI-equipped outlets. 1 Grounded Outlet Grounding Pin Grounding Pin Surge Suppressor Plug in the Power Cord The treadmill must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. The treadmill power cord has a plug with a grounding pin (see drawing 1 on this page). DANGER: Improper connec- tion of the power cord increases the risk of electric shock. Do not modify the plug—-if it will not t an outlet, have a proper outlet installed by a qualied electrician. If you are unsure whether the treadmill is properly grounded, contact a qualied electrician. Plug the power cord into a surge suppressor, and plug the surge suppressor into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances. The outlet must be on a A temporary adapter may 2 be used to 2-pole Receptacle connect the Adapter surge sup- pressor to a 2-pole receptacle Lug if a properly grounded outlet is not Metal Screw available. The lug or wire extending from the adapter must be con- nected with a metal screw to a permanent ground such as a properly grounded outlet box cover. Some 2-pole receptacle outlet box covers are not grounded. Before using an adapter, contact a qualied elec- trician to determine whether the outlet box cover is grounded. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualied electrician. 15
