General wiring guidelines
Inputs
}
Appropriate wiring must be used to exclude short circuits between the inputs or to a
supply line!
}
Signal lines must be shielded.
Outputs
}
If short circuits occur between the cable from the output to the load and a supply line, it
will no longer be possible to switch off the load.
Possible remedy: Exclude the error by using separate multicore cable for supply
voltages
}
Use appropriate wiring to exclude short circuits between the outputs!
}
Signal lines must be shielded.
}
The outputs do not need suppression for inductive loads.
Cable material
}
Use copper wiring.
Please note:
