Danger without protective separation!
DANGER
⇒ The DC 24 V input voltage must comply with the requirements of the "Pro‐
tective 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 obsolete value of 18.5 V is the lower voltage limit.
