The external voltage supply must have a rated voltage of 24 V and
must not exceed an output voltage of 30 V.
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!

Safety isolating transformer according to EN 60742
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.
