Connection To The Power Supply Line - DAB ACTIVE DRIVER PLUS M/T 1.0 Installations- Und Wartungsanleitungen

To improve the immunity to any noise radiated towards other equipment we recommend using separate ducts for the
inverter supply cables.
The installer shall be responsible for checking that the electric power supply system is fitted with an efficient earthing
system according to the regulations in force.
Ensure that all the terminals are fully tightened, paying particular attention to the earth terminal.
Also ensure that the cable clamps are fully secured to guarantee IP55 protection rating.
Check that all the connecting cables are in perfect condition, with the external sheathing unbroken. The motor of the
installed electric pump must comply with the data in Table 2.
Incorrect connection of the earth lines to a terminal other than the earth terminal may cause
irremediable damage to the whole appliance!
Incorrect connection of the power supply line on output terminals intended for the load may
cause irremediable damage to the whole appliance!
2.2.1 Pump connection for M/T and T/T models
The output for the electropump is available on the three-phase cable + earth indicated with the PUMP label.
The motor of the installed electropump must be of the three-phase type with voltage 220-240V for type M/T and 380-
480V for type T/T. To make the correct type of connection of the motor windings, follow the indications on the data
plate or on the terminal board of the electropump.
2.2.2 Pump connection for M/M models
The output for the electropump is available on the single-phase cable + earth indicated with the PUMP label.
Type DV inverters can be connected to motors with power supply 110-127V oppure 220-240V. In order to use the
voltage 220-240V to control the motor in a DV inverter, it is necessary to use a power supply with the same voltage.
For all M/M inverters size 11 and 14 A, ensure that the voltage of the motor used has been correctly
configured, see par. 5.2.5.
M/M inverters size 8.5 A can be connected only to electropumps with a 230V single-phase motor.

2.3 CONNECTION TO THE POWER SUPPLY LINE

CAUTION: The line voltage may change when the electrical pump is started up by the inverter.
The voltage may be subject to variations according to other devices connected, and the quality of the
line.
It is recommended to carry out installation as indicated in the manual, in compliance with the laws, directives and
standards in force in the place of use and depending on the application.
The product contains an inverter inside which there are continuous voltages and currents with high-frequency
components.
The differential switch for protecting the system must be correctly sized according to the characteristics indicated in
Table 2a.

For inverter types T/T it is recommended to use a differential switch protected also against sudden tripping.
