The slots for bus and voltage supply can be confused.
If these slots are confused, you risk destroying the device.
Use only a 4-pin M12 connector for connecting the voltage supply.

• Protect pin 1 of the power supply with 4 A (medium time-lag) fuse and pin 2 with
1 A (medium time-lag) fuse.
• FE (functional earthing) to the earth potential with the shortest possible cable
(0 cm).
