Electric wiring
See the wiring diagram below.
The heater’s
power supply cables
should be connected straight to the battery (red +, blue -). If you need
longer cables, you should change also the original cables to thicker ones so that the area of the wires (mm
2
)
corresponds their length (m); f. ex. 6 meter long wires should be entirely at least 6 mm
2
thick.
NB!
The housing of the heater is galvanic connected to the minus-pole of the battery.
You can connect a separate main switch to the heater and a 20A time delay fuse near the battery (there is a
20A main time delay fuse F1 on the circuit board).
Be careful
not to connect the wires wrong. This would melt the 7,5A fuse F2, which protects the electronics.
Connect the thermostat’s sensor to the connector X10.
The system detects automatically the installed thermostat and changes the Power control on the control
panel to Temperature control.
Connect the pump’s power supply cables to the connector X10
.
Fix
the cables so that water does not get into the heater among them.
