DANGER
Danger without protective separation!
The 24 VDC input voltage must comply with the requirements of the "Protective
separation"!
Plug and unplug the connector only if there is no voltage!
Interfering AC voltage components such as the ones resulting from an uncon‐
trolled three-phase bridge circuit without smoothing and with a ripple factor (see
DIN 40110/10.75, section 1.2) of 5 % are allowed.
That results in the greatest absolute value of 30.2 V as upper voltage limit. The
lowest absolute value of 18.5 V is the lower voltage limit.
For further information please refer to chapter 5.4 "Wiring" on page 29.
