Inspect all protective devices such as insulating materials,cabinet, terminal board, adjustment and compartmentcovers or shields, mechanical insulators etc.3. To be sure that no shock hazard exists, check for leakagecurrent in the

7、following manner.* Plug the AC line cord directly into a 120 volt AC outlet.* Using two clip leads, connect a 1.5k ohm, 10 watt resistorparalleled by a 0.15F capacitor in series with all exposedmetal cabinet parts and a known earth ground, such asconduit or electrical ground connected to earth groun
