PAQ Pin 3 Baseplate Connection The PAQ module has an additional pin 3 on special order that connects to the baseplate but is electrically isolated from the rest of the converter. Please refer to the mechanical drawings. Pin 3 offers a positive method of controlling the electrical potential of the baseplate, indepen- dent of the converter. The baseplate may be ordered by adding a B to the model number tree and pin 3 will be pre- installed by adding a 3. The two options are separate. Please refer to the Ordering Guide. Do not order pin 3 without the baseplate. Note that pin 3 converters may be on limited forecast, requiring minimum order quantities and scheduled deliveries.
