Caution!
If high-energy transients occur when using long signal cables, we recommend connecting a suitable
overvoltage protection (e.g. E+H HAW560/562).
Use shielded signal lines for serial interfaces!
4.3.1 Cable specification, spring terminals
All connections on the rear of the unit are designed as screw or spring terminal blocks with reverse
polarity protection. This makes the connection very quick and easy. The spring terminals are actuated
with a slotted screwdriver (size 0).

Note!
No ferrules need to be used when connecting flexible wires to spring terminals.
