WIRING
Do not run thermocouple or other class 2 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,
auxiliary in or out, and other wiring. See the "Secure Menu" for input selection.
For thermocouple input always use extension leads of the same type desig-
nated 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.
Input wiring for thermocouple, current, and RTD; and output wiring for 15 VDC
is rated CLASS 2.

Wiring to housing terminals while chassis is removed
may cause distortion of the internal connector and pos-
sible damage to the connector when the chasis is re-
installed. It is strongly recomended that the control
housing be wired with the chassis installed.
Control wiring is as shown.
It is not necessary to remove the control chassis from the
housing for installation. If the control chassis is removed
from the housing, you must follow industry standard prac-
tice for control and protection against Electro-Static Dis-
charge (ESD). Failure to exercise good ESD practices may
cause damage to the control.
