• These connectors are suitable for coils with a power rating of 24V DC (-15 or -10%, +10%)
!
• The two lugs on the cover are of different widths to ensure that the connectors
and the cables are oriented correctly (Fig.2)
• ASinterface connectors are non-rotatable.
• Connectors with M12 inputs are available in two versions (A and B), with
M12 orientation through 180° to fit any product configuration.
• It is recommended to connect the wiring before mounting on the coil.
CONNECTION
• Before connection, determine the mounting direction of the connector on
the product coil on the basis of the position of the earth connection.
• The connector is supplied with the cover pre-mounted. Remove the cover
to connect the wiring (Fig.1).
• Completely unscrew the cover screw.
• With a standard screwdriver, unclip the lugs on each side of the lid.

To ensure IP65 leaktightness and prevent short cut on the end line of all
ASinterface connectors:
- At the end of each line or branch of the installation, cut the cables at
least 30 mm after the last connector (Fig.5).
- Fit the 2 flat cables with thermoretractable end-fittings
(available as accessories)
- Shrink these end-fittings at a temperature > 135°C
- Check that gaskets are fitted (Item A) and that connectors and covers
are tight (Fig.6).
When connecting the black cable to the power supply unit
!
24V DC (-5%, +10%), observe polarity: blue to - and brown to +.
