Sensor And Power Cables Routed Through Conduit; Installing The Hm3000 On A Wall - Mace HydroMace 3000 Product Manual

5.2 Sensor and power cables routed through conduit

1. Place the electronics module on a work bench. Using a power drill and 2"
holesaw, carefully drill out the round plastic cable entry point at the base
of the unit as shown below. It is only thin plastic and is designed to break
away. Alternatively, the round cable entry point may be removed using the
"hammer and screwdriver" method described in Chapter 5.1.
2. Use the two "U" bolts,
3 / " nuts and
8
electronics module to the pole.
Do not overtighten the pole mounting bolts as permanent damage may
occur to the electronics enclosure

3. Carefully attach an electrical conduit adaptor (Clipsal 50mm or Carlon 1
to the electronics module.
4. 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
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

5. 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).
6. Once all your cables are plugged in you need to fully test the system.
When you are happy that everything is connected and working properly you
need to fill the cable entry point with expanding "space filler" foam. Fill down
the first 5 to 10cm (2" to 4") of the conduit. This is to prevent insects and/or
moisture damaging the system.
