Terminal Connections
Terminals for connection of customer I/O, external safety circuits etc can be supplied as
industrial connectors, as screwed terminals.
The connector is designated with XP when the equipments are pins and XS when
sleeves. Screw connections is designated with XT.
3.2.1
Connection to connectors
Connectors are located on the left hand side of the control cabinet for the user's
connections.
These may be of two different types:
1. Industrial connectors, DIN 43652, with 4 x 16 poles for contact pressing.
2. Multipole type connectors with 12 poles for contact pressing or soldered connections.
The following applies in general for connection of signal cables:
Fold unused conductors backwards and fix to the cable with cable ties. Check that the
conductors are not connected at the other end of the cable to avoid interference (aerial
effect or cross talk). If there is risk of interference, unconnected conductors should be
connected to ground (0 V).
The following applies when contact pressing connections in and industrial connectors:
A crimp contact is pressed on each stripped conductor with a special tool. The pin can
then be snapped into the connector itself.
A special extration tool is used to remove a pin from the connector.
When two conductors must be connected to the same pin, both conductors are pressed
in the same pin. A wm*iTmiTn of two conductors should be pressed into one pin.
When soldering in multipole connectors, care must be taken to obtain first class
soldering.
