Using Twisted Wire Pairs
It is recommended you use twisted wire pairs for a signal and its return path to
reduce noise levels further. Figure 5.5 shows a twisted pair and shielded twisted
pair.

ATTENTION: Failure to follow correct shielding procedures can
cause unpredictable movement resulting in possible injury to
personnel and damage to equipment.
Connecting AC Power
Figure 5.6 shows AC power and ground connections. Incoming AC connects to
the primary of an isolation transformer. The secondary of the isolation
transformer connects to:
the power supply for the discrete inputs
the power supply for the discrete outputs
the power supply for the I/O chassis
the power supply for the analog outputs
the power supply for the transducer circuits
