Grounding the Sensor Mounting Arm Page 15

GROUNDING THE SENSOR MOUNTING ARM

We strongly recommend that you ground the sensor arm. You will need the

16.5’ (5 m) ground wire, one #8 split lock washer, and one #8-32 hex nut.

1. Slip the ring at the end of the 16.5’ (5 m) ground wire over the lug on the underside of

the sensor arm.

2. Secure the ground wire to the lug using a #8 split lock washer and a #8-32 hex nut.

SECURE GROUND WIRE TO SENSOR ARM

3. Connect the other end of the ground wire to a suitable earth ground (grounded metal

cold water pipe or ground rod driven into the earth).

SAFETY AND BUILDING CODES

When installing the Sensor Mounting Arm, a 2” (5 cm) pipe should be ade-

quate for general homeowner’s backyard or open-ﬁeld agricultural locations

for a mounting height of 6 to 8 feet (2 to 2.5 m) provided that low wind-loading

conditions apply and the pipe is anchored to a suitable foundation. (If you are

unsure, consult a qualiﬁed professional for national and local codes.)

Regardless of the mounting location, local building codes must be followed. If

you want to mount onto a taller mast, a building, or any location where high

wind or seismic loads might be encountered, seek professional help from a

structural engineer or local contractor. Remember always to use common

sense.

When installing the Sensor Mounting Arm and sensors, always watch for over-

head power lines. Electric shock, death, or damage to the sensitive electronics

could result if you or the sensors come in contact with electric power lines.
