Safety Interlock Pin Active high input. >3.4 V @ 24 mA (absolute maximum of 6 V) must be externally applied to this pin
to ensure 200 V operation. This signal is pulled down to chassis ground with a 10 kΩ resistor. 200
V operation will be blocked when the INTERLOCK signal is <0.4 V (absolute minimum –0.4 V). See
