5V Power Supply Pins: Limited to 250mA total for all three pins, solid state fuse protected.
Safety Interlock Pin: Active high input. >3.4V @ 24mA (absolute maximum of 6V) must
be externally applied to this pin to ensure 200V operation. This signal is pulled down
to chassis ground with a 10kW resistor. 200V operation will be blocked when the
INTERLOCK signal is <0.4V (absolute minimum –0.4V). See figure below:
