WIRING
Do not run transmitter wiring or other Class 2 wiring in the same conduit as power
leads. Use only the probe or transmitter 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.
Supply connections should be made in accordance with the National Electrical
Code per Article 300, and local regulations. All line voltage output circuits must
have a common disconnect and be connected to the same pole of the disconnect.
Input wiring for probe or transmitter is rated CLASS 2.
Control wiring is as shown in Figure 2 below.
