1. ELECTRIC INSTALLATION
The electrical connection should be carried out by an authorized electrician in
accordance with local regulations. Do not remove motor terminal box covers,
electrical cables or any other electrical protective covering without first ensuring
that the electrical supply is suitably isolated. Do not attempt to supply electricity
to the pump without ensuring that all electrical fittings, cables and enclosures are
intact and suitably electrically isolated from human touch during operation.
Electric connection for the pump
The pump requires no external motor protection. Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
The pump must not be used with an external speed control which varies the supply voltage,
for example phase-cut or pulse-cascade control.
The supplied pumps are delivered with molex 3-pin plug and cable to moved out of the pump
group casing. Connect power supply to the three leads L, N and PE.
Line/phase: L (brown
Neutral : N (blue)
Protective earth: (yellow/green )
The cable size to be used is 3 core 0.75mm2. The cable should be capable of withstanding a
minimum temperature of 80°C.
Electric connection for the valve actuator
To of the valve actuator use cable 3x 075mm2 according to make electrical connection below
scheme.
