6.1 CONNECTING MECHANICAL LIMIT SWITCHES
The wiring is preset for encoder limit switch. To set-up the control unit to mechanical limit switch it’s needed to
modify the wiring as shown below (fig. 6).
The limit switches connector (1) of the multicore cable NRGCAB must
be connected to the male connector (2) of the cable the control unit is
provided with (Fig. 6a).

WARNING: connect a control unit pre-set for mechanical limits to a motor with encoder limits, the motor does
not perform correctly. In particular, the motor will not find the limit positions and this could put at risk the
safety of people and/or things.
