Cabling
•
for devices which have only one CAN connector use T-connector and dead-end feeder (shorter than
0.3 m) (available as accessory)

Example for correct wiring (when using single shielded wires)
Terminal Resistance
•
use
external
terminator, because this CAN later be found again more easily!
•
9-pin DSUB terminator with male and female contacts and earth terminal are available as
accessories
Earthing
•
CAN_GND has to be conducted in the CAN wire, because the individual esd modules are
electrically insulated from each other!
•
CAN_GND has to be connected to the earth potential (PE) at
exactly one
point in the net!
•
each CAN user without electrically insulated interface works as an earthing, therefore: do not
connect more than one user without potential separation!
•
Earthing CAN e.g. be made at a connector
