Warning!
Only connect to the main power network
when the power is switched off.
Only use power interruption devices
which ensure that the power cannot be
switched on again unintentionally.
Particularly for 24 V, 50 Hz actuators,
use wires with a sufficiently large cross-
section to guarantee that the permissible
voltage tolerances are not exceeded.
