2.5.1.1.6. Plug-in connector on the module
As terminal block, user-friendly terminal strips with locking protection and
ejection mechanism are used. They are reverse-polarity protected and allow
quick replugging. The wire connection itself is realised with a screwless
connector system. A tool is included with each module.
2.5.1.1.6.1. Connection wiring
Connecting the wires is to be effected at the ports with the same numbering, for
example: 1a & 1b, 2a & 2b. ...
The optocoupler inputs are suitable for AC voltage. Therefore it is not necessary
to take care of the connection polarity.
The figure shows two terminal blocks with numbered connection ports.
