the terminal board!
According to the European Standard EN809 a
motor overload must be installed and properly set
to the full load amps stated on the pump name
plate.
It is the responsibility of the machine operator to

switch must be installed.
5.2.1 Circuit
Tension voltage and frequency must correspond
with the shown specification on the
The pump must be wired so that a solid long term

Delta connection
3 x 230 V, 50 Hz
resp. 220-240 V, 50 Hz
There may be no foreign objects such as dirt,
particles or humidity inside the terminal board.
Mount terminal board cover to motor tight against
dust and humidity and close up all unused wiring

ing signals might occur.
Non-sinus shaped supply voltage from a variable
frequency drive might result in elevated motor
temperatures.
