[3] When wiring from a pole, cut the rubber bumps with scissors by referring to the wiring holes on page 15,
and put wires through the installation base.
Do not use an electric screwdriver when mounting the unit to a pole.
Adjust the position so that the front of the base
faces the desired angle, and mount it to the pole.
Adjusting the angle after the base is mounted
NOTE
Rotate the sensor unit to adjust the angle.
The sensor angle is adjustable up to 96 degrees to the left and right
in 3 degree increments.
[4] Connect wires to the terminals.
Connect the power supply to the power supply terminals, and relay output cables to the output terminals.
When linking to other devices or when a connected billing machine has billing information outputs,

Cut the rubber bump with scissors and make a hole according to the wire diameter. (Select the smallest
from among similar sizes.)
CAUTION
Apply silicon adhesive and fill the hole. When doing so, be careful not to overfill the adhesive over the hole.
If the unit is used with holes left open, its waterproof property will be degraded and it may result in
breakage.
When pilot holes of 4.3mm (0.17in.) have been made, use
M4 screws (included) and nuts (not included) for mounting.
