1. Critical Components information.
Components having special characteristics are marked and
must be replaced with parts having specifications equal to
those originally installed.
2. Leakage Current
Measurement (For 120V Model only).
When service has been completed, it is imperative that you
verify that all exposed conductive surfaces are properly insu-
lated from supply circuits.
Meter impedance should be equivalent to 1500 ohm shunted by
0.15µF.
Leakage current must not exceed 0.5mA.
Be sure to test for leakage with the AC plug in both polarities.
