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.
