Control signal terminal 12 (STO+) must always be connected to
+24 V and control signal terminal 13 (STO-) must always be
connected to 0 V (reference point for +24 V)!
Without the connection of a power supply (24 V DC) to control signal
terminals 12 and 13, the control section and the inverter will remain blocked.
An Inhibt (Inhibit = block) message is displayed.
The control cables should be screened and twisted. The screen is applied on
one side in the proximity of the variable frequency drive (PES).
