Installation
Single phase broad
range voltage motor
The mains voltage must be determined on-site each time before the pump is installed
or moved to a different location.

Connection diagram (terminal box)
Changing the voltage range
Disconnect the pump from the power supply.
Set the rocker switch "S" in the motor terminal box to the desired voltage range.
Fuse protection
To protect the motor in case of malfunction, carry out fuse protection in accordance
with the regional regulations.
– Select a fuse with slow characteristics.
The transmission power of the pump’s magnetic coupling is so great that there is
no overload protection for the motor.
NOTICE
Overvoltage!
An incorrect voltage range setting can damage the motor.
Disconnect the pump from the power supply.
Only change the voltage range when the pump is disconnected from the power
mains.
