UWQ Pin 9 Baseplate Connection The UWQ module has an additional pin 9 on special order that connects to the baseplate but is Customer Confi guration Part Number electrically isolated from the rest of the converter. Please refer to the mechanical drawings. 1. UWQ-12/17-Q48NTBL2-C-CIS Pin 9 offers a positive method of controlling the electrical potential of the baseplate, indepen- dent of the converter. 2. UWQ-12/17-Q48NTL2-C-CIS The baseplate may be ordered by adding a “B” to the model number tree and pin 9 will be pre- installed by adding a “9.” The two options are separate. Please refer to the Ordering Guide. Do not order pin 9 without the baseplate. Note that “pin 9” converters may be on limited forecast, requiring minimum order quantities and scheduled deliveries.
