To install the RF module
1. Locate the RF module atop the mounting pipe and insert a U-bolt around the pole
and up through the bracket. Place a spacer over each section of the U-bolt
protruding through the bracket and place a lock washer and nut over each side of
the U-bolt. Repeat for the other U-bolt.
Note: Depending on pole diameter, spacers may or may not be needed.
2. Tighten nuts with torque wrench to 68 N-m (50 ft-lb). Tighten second nut over
first nut to lock it in place.
3. Check that 19 to 28 VAC or 16 to 28 VDC power is available at the module end
of the power cable. Measure the voltage across pins A and C of the power cable
connector.
4. Connect the power cable to the RF module’s power supply plug (Figure 4-14).
5. Connect the data cable to the RF module’s data connector.
