– Establish an earth connection (A) to the pump or pump unit.
– Check whether the motor connection matches the mains voltage. See the type plate for the motor.
Check the connections in the terminal box behind the control panel.
7.3 Electrical connection
Motors up to 3 kW (4 hp)
The type plate is labelled 230V/400V.
This means the winding voltage of the motor may not exceed 230V
. The 400V indicates the voltage
between the phases. 3x400V is three-phase electric power. This means the motor must be connected
in STAR configuration (see technical specifications BA series).
Motors of 3 kW (4 hp) or more
The type plate is labelled 400V/690V.
This means the winding voltage of the motor may not exceed 400V. Because the maximum voltage is
400V, this motor must be connected in a DELTA configuration (see technical specifications BA series).
7.4 Control panel
The pump unit has a control panel that can be fitted with a built-in soft-starter. There are various types
of panels for different pump units.
Note
