3. Electrical Installation
1. Pump wiring: The motor must be connected to the ter-
minals L1, L2, L3 and GROUND. Observe rotation direction.
2. Accessories wiring: Connect a source low sensor to
terminals 1 and 2 (required), remote control switches to
terminals 3 and 4, water detection sensor for surface pump
to terminals 5 and 6, SunSensor module to terminals 7
and 8, analog sensors to terminals 9 and 10 or 11 and 12,
water meter to terminals 13 and 14.
3. DC input wiring: Connect the positive terminal of the
PV array to +, the negative terminal to −. Observe max.

4. Grounding: A protective earth connection must be
wired to GND .
4. Pump Installation
Submersible pumps: Lower the pump into the water
source with caution, use a safety rope.
Surface pumps: Install the surface pump on an adequate
