DAB PUMPS PWM 201, Instruction For Installation And Maintenance

The rated voltage of the electric pump must be the same as the supply voltage of the inverter.
The rated frequency of the electric pump can be set via the display according to the specifications on the manufacturer’s dataplate.
For example, the inverter can also be powered at 50 [Hz] with control of an electric pump at 60 [Hz] - nominal (provided that the
pump is declared as compatible for this frequency).
For special applications, pumps are also available with frequency up to 200 [Hz].
The utility connected to the inverter must not absorb current in excess of the maximum values specified in Table 1.
Check the dataplates and type of motor connection (star or delta) used to ensure compliance with the above conditions.
2.2.1.4 Electrical connections to the electric pump PWM 203 – 202 – 201
Models PWM 203 – 202 – 201 require motor configuration for a three-phase voltage of 230V. This is normally obtained by a delta
configuration of the motor. See Figure 5.

Incorrect connection of the earthing line, to a terminal other than the earth terminal can cause irremediable
damage to the equipment.
Incorrect connection of the power line on the output load terminals can cause irremediable damage to the
equipment.
