Procedure
Note
Specications for connecting the relay module
• The cables connected must be suitable for the voltage used and have appropriate (double or
reinforced) insulation. Cables with an external diameter of 6 to 7 mm are recommended.
• Components of the controller and connecting cable, such as the motor plug and its wires,
may only come in contact with the additional (or reinforced) insulation of the current-
carrying wires.
① Cable ties (strain relief in housing)
② Cable ties (security against being pulled out within the protective cover)
③ Minimum length of the cable jacket within the protective cover: 5 mm
④ Minimum length of the single-insulation on the single cores: 5 mm
⑤ Insertion direction for the protective cover
1. Unscrew the xing screw holding the protective cover on the relay module.
2. Slide the protective cover against the insertion direction and remove it.
3. Connect connectors X11, X12 and X13.
4. Ensure that, inside the cover, the single-insulation is removed from the single cores at least
5 mm from the cable entry openings, and the cores connected to the terminal connectors are
as short as possible.
5. Secure the cables inside the plastic cover against being pulled out through the oval aperture
in the relay cover. Use cable ties for this purpose, tie each of them tightly round the cable.
Ensure that the cable tie is tied so that at least 5 mm of the outer cable jacket lies inside the
protective cover.
6. Provide additional strain relief by attaching more cable ties to the xing points provided in the
housing.
