Switched/unswitched 24 V power supply
The unswitched (also known as "non-switched") 24 V power supply (1L+) is required for the drive
to function.
• Use a power supply with PELV (Protective Extra Low Voltage).
• The 0 V of the power supply must be connected with low resistance to the PE of the system.
The switched 24 V (2L+) supplies the two bidirectional digital inputs/outputs DIO 24 and DIO
25. Switching off the 24 V power supply voltage brings all of the actuators connected to the
digital outputs into the no-voltage state.
If you don't need the switching of 2L+ power supply, you can connect the conductors 2M
(switched 0 V) to 1M (unswitched 0 V) and 2L+ (switched 24 V) to 1L+ (unswitched 24 V)
