(a) Pin 27 of every slot is always connected to ground. When a jumper is connected across TB7,
pin 1 and pin 27 of each slot are connected together. This attaches both pins to frame (chassis)
ground. See
frame ground for proper fault protection. The enclosure is shipped without a jumper across TB7.
Figure 3
shows the backplane wiring connections to slots 1 through 6. (For backplane connections to slot 7, refer
to the PSC-606 technical practice, document number 150-606-100-xx.)
