Chapter 2: Installation

Pole mounting instructions for V104s (Inside Pole)

Required tools:

 5 mm Allen key for M6 screws and adjustable wrench to 

tighten jam nut

1.

Insert mating cable through both the jam nut and 1” (25.4mm) 
mounting adapter base

2.

Place the jam nut on the pole followed by the 1” (25.4mm) adapter 
base. Hand tighten the base to the desired orientation. 

3.

Adjust the jam nut to secure the orientation.

4.

Connect the mating end of the cable to the V104s connector located 
on the bottom of the unit.

5.

Insert the base adapter into V104s by placing the tongue of the base 
into the groove of the V104s unit. When the tongue is properly 
seated in the groove, the rest of the base can be pressed into place 
to create a smooth seam between the base and V104s unit. 

6.

Use 5 mm Allen key to fasten two M6 screws to secure V104s onto 
adapter. Use 15 in-lb torque

7.

Insert each o-ring onto a plastic cap

8.

Install plastic cap with o-ring onto V104s unit (rectangular notch 
faced towards the outside)

9.

Align and set the direction of V104s unit, while using the jam nut to 
secure the unit (hand-tighten).

 Over-tightening may damage the system. This is not covered 

under warranty.
