2.5 Agricultural Farm Sensor Mounting
On the Farm model of the Agricultural Sensor, there is a mounting bracket on the bottom of the
unit. See Figure 4. These mounting holes can be used to screw the enclosure to a solid surface.
The recommended mounting screw size is M3 or #6. Mounting screws are not provided with
the sensor.
Figure 4 Mounting Holes
The mounting surface must be capable of holding > 2 kg [4.5 lbs]. Clearance must be provided
for the modules cable gland and input cable.
2.6 Cable Installation
The Agriculture Sensor enclosure is provided with a waterproof cable gland through which all
connections must be routed. The supplied cable gland size is PG-7. This gland supports cables with a
jacket outside diameter of 3.0 mm to 4.3 mm (0.118" to 0.169").
The I/O terminal blocks accept 30-16 AWG wire. Select a cable that meets the application
requirements and local and national electrical codes.
Figure 3 shows the terminal block wiring connections. To install the cable, first make the
appropriate connections between the input cable and the terminal block. Next dress the
internal wires so that the cable gland seals against the outer cable jacket. Finally, tighten the
cable gland.
