When exposed to outdoor conditions, it is necessary to route cable through conduit. In cases
such as this, the quick-connect cable must be extended or replaced with four-conductor, 22-
AWG, shielded cable. The maximum length of the cable should be no more than 500 feet.
Mounting to a sheet metal surface
Follow these instructions when mounting the sensor to a sheet metal surface:
1. Drill two pilot holes using a 5/32” drill bit. Horizontally space the holes 1.5” apart.
2. Insert two self-drilling screws through the holes of the mounting bracket, and screw
into the pilot holes.
3. Route cable up to the quick-connect jack on the back of the display and plug into J31.
Refer to
Section 1.3 for an example of connection.
1.3 Temperature Signal Connection
Three options for signal connection are explained in this section:
•
Using the 25-foot quick-connect cable.
•
Using the quick-connect cable but less than 25 feet.
•
Using more than 25-feet including extension cables or 22 AWG shielded cable.
Using the provided 25-foot quick-connect cable
Figure 5: Quick-connect Cable
1.
The temperature sensor is provided with a 25-foot weather-
resistant cable. This cable does not need to be in conduit. The
sensor connects to the display at J31. Refer to
Figure 5 for the
location of the quick-connect plug.
2.
Secure any excess cable to discourage vandalism.
3.
Between displays, the quick-connect signal cable connects
both communication and temperature signal, thus no
additional wiring is required from display to display for the
temperature sensor.
