SECTION 5. ELECTRICAL CONNECTION
The electrical motor must be wired by a professional accord-
ing to this installation instruction and all applicable local reg-
ulations.By introduction of the pump a motor security has to
be foreseen by the installation. The security has to be tuned
into the nominal power of the motor.
The supply voltage should be within ±5% of the rated
voltage,on the nameplate of the motor.
Single-phase motors should be connected at the two ter-
minals as indicated below. Single phase wiring diagram :
Make sure that you interrupt the power supply to the
cables when connecting the cables of the pump
Please remove lead wires from terminalsprior
to installation !
Please check the turning direction of three-phase motors
following each connection. If this does not correspond to
the arrow on the pump, two phase connections in the
junction box must be reversed. Every motor must be
permanently grounded.
Connections which do not conform to the above
mentioned safety instruction are not covered by the
warranty.
Section 6. Servicing
The pump is designed to operate for many years without
servicing. Always disconnect the power supply to the
pump before servicing. The replacement of the electrical
motor must be done by a professional.
