All wiring connections are made to the rear screw
terminals. When wiring the controller, use the numbers on
the label and those embossed on the back of the case, to
identify the position number with the proper function.
All conductors should meet voltage and current ratings
for each terminal. Also, cabling should conform to
appropriate standards of good installation, local codes and
regulations. It is recommended that power (AC or DC)
supplied to the controller be protected by a fuse or circuit
breaker. Strip the wire, leaving approximately 1/4" (6 mm)
bare wire exposed (stranded wires should be tinned with
solder). Insert the wire under the clamping washer and
tighten the screw until the wire is clamped tightly.

For best results, the power should be relatively “clean” and
within the specified limits. Drawing power from heavily loaded
circuits or from circuits that also power loads that cycle on and
off should be avoided. It is recommended that power supplied
to the controller be protected by a fuse or circuit breaker.

For two wire RTDs, install a copper sense lead of the same gauge and
length as the RTD leads. Attach one end of the wire at the probe and the
other end to input common terminal. This is the preferred method as it
provides complete lead wire compensation. If a sense wire is not used,
then use a jumper. A temperature offset error will exist. The error may be
compensated by programming a temperature offset.
