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)
