SERVICE SAFETY PRECAUTIONS (UL)
1. Use exact replacement parts for critical locations marked ANG
2. Return lead dress to original position and re-install protective covers.
3. Before returning to customer, test for shock hazard; use either mothod A or B:
A. Leakage test “cold”:
1. Unpiug the AC cord; turn power switch ON.
2. Connect one lead of High Voltage Insulation Tester to both prongs of the AC plug.
3. Touch other lead to all exposed metal parts. :
4. Impedance measurement must be 0.3-5.0 Megohms.
B. Leakage test, “live” :
1. Plug unit directly into the AC outlet: do not use isolation transformer.
2. Connect one lead of the Leakage Current Tester to earth ground.
3. Touch other jead to all exposed metal parts.
4, Leakage measurement must be less than 0.5 milliamps.
