Wiring
General wiring guidelines
Note:
} Information given in the "Technical details" must be followed.
} Use copper wire that can withstand 75 °C.
} The wiring must be designed to achieve sufficient noise immunity and protection
against noise emissions in terms of EMC. Please also refer to DINEN60204-1 (Elec-
trical equipment of machines).
Inputs
} Appropriate wiring must be used to exclude short circuits between the inputs or to a
supply line!
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!
