ou will find all inputs and outputs on the S3000 on the 30-pin screw terminal connection
in the system plug. You can either make connections directly to the terminal strip on the
system plug or use a pre-assembled system plug from SICK (see section 6.3 on page 101).
The system plug pin assignments vary depending on the S3000 variant.
 If the cable gland/blanking plug is missing or not tightened, or if fixing screws are
missing or not tightened on the system plug, the IP 65 enclosure rating is not met.
 All inputs and outputs on the S3000 are to be used only in the context specified.
Wiring in accordance with EMC regulations
The quality of the shield is essentially dependent on the quality of the connection of the
screen. In principle the best screening action can only be achieved with the connection of
the screen at both ends using large area connections.
 To connect the screen on the S3000 use the EMC cable glands M12 (see Tab. 50 on
page 165).
 Use similar cable glands on the incremental encoders.
 If it is not possible to connect the screen via threaded fittings (e.g. on bus nodes),
connect the screen physically close, e.g. to a control cabinet chassis using a metal
clamp.
 If you want to operate two safety laser scanners in a system (communication via EFI),
then the same earthing method must be used for both safety laser scanners.
 If there is a PE in an installation, it can be used for the connection of the FE. However a
functional earth connection (FE) is never allowed to be used as a PE!
Functional earth
To achieve the specified EMC safety, the functional earth FE must be connected (e.g. to
the vehicle’s or system’s central earth star point).
Unlike the S300 and the S300 Mini, the S3000 has no separate functional earth
connection (FE). If required for the application, an FE connection can be connected to the
housing (the S3000 complies with electrical protection class II and for this reason the
housing can be used for the connection of this functional earth).
