Caution:
For proper operation of a device equipped with electrical actuators, it is recommended that the rated
voltage housed tolerance of 24V±10% or 230V±10%. Power supply devices other than listed above may
cause malfunction and will not be covered by the warranty conditions.
RST/KW1 trigger control gear
The RST/KW1/S version has the limit switches installed in the gear itself. The electrical connections shall
be made by connecting the properly labelled conductors to the electrical system. A fusible trigger is
installed in the gear. The dampers with the RST/KW1/230I, RST/KW1/230P mechanisms, are supplied
with the RST/KW1/24... triggering and control mechanism, together with the 230/24V transformer module
type MP230/24. For the trigger and control mechanism of the "impulse" type damper, adequate power
must be provided to ensure that the control signal is supplied to the device in the event of fire.
