Table 5.1:

 Preferably, use the "KD S-M12-8A-P1-..." ready-made cables, see table 9.6 "PWR
cables for the LSIS 4xxi" on page 54.
Supply voltage
Attention!
For UL applications, use is only permitted in class 2 circuits in accordance with the NEC
(National Electric Code).
The smart cameras of the LSIS
for supply by PELV (protective extra-low voltage) / SELV (safety extra-low voltage).
Connecting functional earth FE
 Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only
guaranteed when the functional earth is connected properly. All electrical disturbances
(EMC couplings) are discharged via the functional earth connection.
Switching input / output
The smart cameras LSIS
inputs / outputs IO1 ... IO8.
The switching inputs can be used to activate various internal functions of the LSIS
(triggering of image acquisition, check program selection ...). The switching outputs are
used for the output of result and status messages and for triggering an external flash control.
Switching inputs/outputs IO1 to IO4 are located on the PWR M12 connector.
Switching inputs/outputs IO5 to IO8 are located on the BUS OUT M12-socket.
