Max. cross-section that can be connected: 1.5 mm²
Type: Screw terminal 1 (see Appendix A)
1) DI: digital input; M: electronic ground; M2: Ground reference
Notice
An open input is interpreted as "low".
To enable the digital inputs to work, terminal M2 must be connected. This can be done as
follows:
1) Route the reference ground of the digital inputs (with the other cable) and connect it to
M2.
2) Jumper terminal M and M2 directly
(the electrical isolation for these digital inputs is therefore removed).
