Precautions willprevent electrostatic discharges from personnel and handtools which are held during the procedure. Theseprecautions will help to avoid exposing the control toelectrostatic discharge by putting the furnace, the control,and the person at the same electrostatic potential.CAUTION!1. Disconnect all power to the furnace. Multiple disconnectsmaybe required. DO NOT TOUCH THE CONTROL ORANY WIRE CONNECTED TO THE CONTROL PRIORTO DISCHARGING YOUR BODY’SELECTROSTATIC CHARGE TO GROUND.2. Firmly touch the clean, unpainted, metal surface of the fur-nace chassis which is close to the control. Firmly touchthe clean, unpainted, metal surface of the furnace chassiswhich is close to the control. Tools held in a person’s handduring grounding will be satisfactorily discharged.3. After touching the chassis, you may proceed to service thecontrol or connecting wires as long as you do nothing torecharge your body with static electricity (for example;DO NOT move or shuffle your feet, do not touch un-grounded objects, etc.)4. If you touch ungrounded objects (and recharge your bodywith static electricity), firmly touch a clean, unpaintedmetal surface of the furnace again before touching controlor wires.5. Use this procedure for installed and uninstalled (ungroun-ded) furnaces.6. Before removing a new control from its container, dis-charge your body’s electrostatic charge to ground to pro-tect the control from damage. If the control is to be in-stalled in a furnace, follow items 1 through 4 beforebringing the control or yourself in contact with the fur-nace. Put all used and new controls into containers beforetouching ungrounded objects.7. An ESD service kit (available from commercial sources)may also be used to prevent ESD damage.58DL
