The 24 V output is not suited to supply external safety circuits because an external voltage source is
necessary to comply with the applicable standards.
Note
The power supply unit is only activated when SAFE A and SAFE B are connected. If the
safety function is not required, pin A5 and pin A6 must be bridged to pin A4.
Specification of terminal connections
