4.5 Connection Variants
This chapter describes the correct wiring of the module in safety-related applications. The
connection variants specified here are permitted.
The outputs are wired via connector boards. Special Connector Boards are available for
redundantly wiring the modules, see Chapter
3.6.
The following points must be taken into account when connecting the loads to the outputs:
 A protective circuit (such as free-wheeling diode or varistor) is required when connecting
inductive loads.
 Unshielded, twisted pairs of cables may be connected.
 The ground wires of the outputs may not be interconnected.
