Incorrect connection of the earthing line, to a terminal other than the earth terminal can cause irremediable
damage to the equipment.
Incorrect connection of the power line on the output load terminals can cause irremediable damage to the
equipment.

Hydraulic connections

The inverter is connected to the hydraulic section by means of pressure and flow sensors. The pressure sensor is always required,
while the flow sensor is optional if operating in stand alone mode, and is compulsory when creating multi inverter systems.
Both are mounted on pump delivery and connected by means of the relative cables to the respective inputs on the inverter board.
Always fit a check valve on pump suction and an expansion vessel on pump delivery.
In all circuits subject to the risk of water hammer (for example irrigation systems with flow rate interrupted suddenly by solenoid valves),
fit a further check valve downline of the pump and mount the sensors and expansion vessel between the pump and valve.
