Page 7: Electric Connections
4.2 Electric connections Power supply AC: L(L1), N(L2), P.E. DC: L(L1), N(L2), P.E. In the case of DC power supply it is not necessary to respect the polarity. Connect only one power source (AC or DC) at a time. It is recommended to use pre-insulated female faston terminals 6,3x0,8 mm. - Page 8 Motor output U (red), V (black), W (blue), P.E. Respect the correspondence of colors and phases to ensure the correct rotation sense. Failure to comply with this recommendation will result in a drastic reduction in performance and possible damage to the pump itself. Analog inputs (sensors) ...
- Page 9 Digital inputs • IN1 : motor start / stop • IN2 : motor start / stop or set value 1 - 2 switching* * only when “control mode: constant value 2 values” is selected. It is recommended to use only volt free contacts. Digital inputs can be configured as Normally Open or Normally Closed by software.

Page 10: Protections
4.2.1 Protections The necessary protections depend on the type of installation and the local regulations. In the case of both DC and AC power supply, it is necessary to provide the safety protections for both DC side and AC side. For the DC side it is recommended to use a DC switch with current protection (fuses) and surge protection (surge arrestor). -
