5.7 SAFETY INTERLOCK SWITCH
While the Amplifier's top cover is in place, the interlock switch closes to allow AC line voltage
to reach the power transformer. When the top cover is removed, the interlock switch opens and
disconnects the line voltage. This does not discharge the bank of power supply filter
capacitors. Be sure to allow the filter capacitors to discharge before you touch anything inside
the Amplifier. You can select the High Voltage function of the Multimeter to check the high
voltage potential.
