Warning! - Location of limit switches of the mechanism was shown for the damper safety position
For proper operation of a device equipped with electrical actuators, it is recommended that the rated voltage housed
tolerance of 24V±2% or 230V±2%. Power supply devices other than listed above may cause malfunction and will not
be covered by the warranty conditions.
Release and control mechanism RST
In the RST version, the limit switches are installed inside the damper enclosure as independent subassemblies. The
fuse release can be found on the damper partition. The drive spring is installed on the damper partition.
In order to install the fuse release in the RST version:
Set the damper partition in the open position
We put the fuse cells on hooks attached to the damper body and to the partition.
We draw in and lock the hook on the damper body by tightening the nut.
