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.
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
▶ Conductor cross-section solid/stranded: 0.2 to 1.5 mm²
▶ Connection method: spring-cage connection (handling: see page 39)
