Connection Of User Inputs; Table 5: Input Connection - DAB ACTIVE DRIVER PLUS M/T 1.0 Installations- Und Wartungsanleitungen

The current supply to the inverter can normally be calculated (taking a safety margin into account) as 1/8 of the
current absorbed by the pump.
Although the inverter is already equipped with internal safety devices, the installation of a suitably sized thermal
magnetic circuit breaker is recommended.
If the entire power range available is used, for specific information on the current to be used when choosing cables
and the thermal magnetic circuit breaker, refer to Table 4.
2.3.3

Connection of user inputs

In inverters type M/T and T/T, the inputs can be switched on using either direct current or alternating current at 50-60
Hz. In type M/M the input can be activated only with a clean contact inserted between the two pins.
The wiring diagram and the electrical characteristics of the inputs are shown below.
