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.
