Notes:
Without the block, the grounding is made the same way.
Notes:
•
Do not ground the outer shield of the cable here since it is grounded at the lead-
through.
•
Keep any signal wire pairs twisted as close to the terminals as possible. Twisting t
wire with its return wire reduces disturbances caused by inductive coupling.
