Installing The Hm3000 On A 2" Pole; Sensor And Power Cables Routed Inside The Pole - Mace HydroMace 3000 Product Manual

5.0 Installing the hM3000 on a 2" pole

The sensor and power cables can be routed either directly through the inside
of the 2" mounting pole or through electrical conduit. Installation directions
for both are provided below.
MaCe recommends that the hM3000 electronics module be mounted so
that the LCD faces in a direction away from direct sunlight.

5.1 Sensor and power cables routed inside the pole

1. Place the electronics module on a work bench and using a hammer and
screwdriver carefully knock out the plastic cable entry point from the rear
of the enclosure. It is only thin plastic and is designed to break away at the
edges so work your way around the edge of the oval shape until the cover is
completely broken free of the unit.
2. File away any rough edges from the plastic cable entry point
1
IMpOrtaNt: apply NON-aCIDIC cure silicon sealant to the back of the
electronics module in the channel around the cable entry point. this will
stop water flowing down the pole and into the electronics module
3. Hold the electronics module up against the pole so that the oval cut-away
on the pole matches the cable entry point. Route the sensor and power
cables through the cable entry point as shown.

electronics module to the pole.
Do not overtighten the pole mounting bolts as permanent
damage may occur to the electronics enclosure
5. Plug in both the sensor cable and solar panel cable into the sockets as
shown in the picture below.
Sensor cables should be looped prior to connecting to act as a
form of strain relief.
4
ensure that the cable from the solar panel/charger is terminated
using the three-pin connector provided in the electronics box and
that the polarity is correct. the polarity is labelled on the circuit
board near the connector
6. If using a 16-30VDC mains charger then plug this into the socket shown
in the picture below. Alternatively, the charger may be wired into the solar
panel screw terminal block (to the left of the socket).
7. Once all the cables are connected the system should be fully tested.
Assuming everything is connected and fully functional the cable entry point
should be filled with expanding "space filler" foam. This is to prevent insects
and/or moisture damaging the system.
