CAUTION!
4
Only connect to the mains power net-
work when the power is switched off.
4
Only use power interruption devices
which ensure that the power cannot be
switched on again unintentionally.
4
Particularly for 24 V/50 Hz actuators,
use wires with a sufficiently large
cross-section to guarantee that the per-
missible voltage tolerances are not ex-
ceeded.
