WIRING
Do not run thermocouple or other input wiring in the same conduit as
power leads. Use only the type of thermocouple or RTD probe for which
the control has been programmed. Maintain separation between wiring
of sensor, auxilliary in or out, and other wiring. See the "Secure Menu"
for input selection.
For thermocouple input always use extension leads of the same type
designated for your thermocouple.
For supply connections use No. 16 AWG or larger wires rated for at least
75°C. Use copper conductors only. All line voltage output circuits must
have a common disconnect and be connected to the same pole of the
disconnect.
Wiring to housing terminals while chassis is re-
moved may cause distortion of the internal connec-
tor and possible damage to the connector when the
chasis is re-installed. It is strongly recomended that
the control housing be wired with the chassis in-
stalled.
Control wiring is shown below.
