inductive loads. Be sure to place the transient suppressor as close to
the load as possible. Examples of transient suppressors include MOVs,
TRANSORBs, and RC snubbers.
AC mains supply wiring should not be run in the same conduit with
mains supply wiring that feeds heavy inductive loads.
Avoid running signal wiring in the same cable or conduit with wires
that power inductive loads unless all the cables within the conduit are
shielded, the inductive loads are small, and transient suppressors are
used at the loads.
Do not run signal lines in the same cable or conduit with high voltage
lines.
For optimum noise protection, control unit mains supply wiring
should be connected to a circuit separate from any circuit that could
introduce transients into the system. As an example, do not run mo-
tors, blowers, or air conditioners using the same mains supply circuit
or conduit as the control unit's mains supply circuit or conduit.

sensor Connections

Make sure that power has been removed from the control unit and
sensor before making sensor connections. See Figure 3-25, Sensor
Board.
This section describes required wiring connections between the control
unit and the sensor. Follow the connection instructions for the applicable
options for your analyzer. All sensor connections require that you access
the sensor board (see Figure 3-19).
Sensor cabling must be twisted pairs in an overall braided shield, or

twisted pairs in rigid metal conduit. Follow all wiring guidelines as
specified in Figure 3-17 in the front of this wiring section.
