An auxiliary contact (NO contact) of a limit
resistor MC, a limit resistor (with thermostat)
(NC contact), and a filter capacitor alarm
detector (NC contact, 400K, 560K) are
connected to stop the converter operation
when overheating of the limit resistor
becomes a concern and when a filter
capacitor is faulty.
