Smart Infrastructure 2020-01-09
Disposal
The device contains electrical and electronic components and must not be dis-
posed of together with domestic waste. This applies in particular to the PCB.
Before disposal the valve must be dismantled and separated into its various con-
stituent materials.
Legislation may demand special handling of certain components, or it may be sen-
sible from an ecological point of view.
Current local legislation must be observed.
Warranty
The technical data relating to specific applications are valid only in conjunction with
the control devices listed in this data sheet under «Type summary», page 2.
Approval as actuating device with safety function as per DIN EN 14597 ap-
plies to the entire actuator. Approval as actuating device with safety function
as per DIN EN 14597 expires if the actuator is separated from the valve. This
also voids any guarantees on the part of Siemens Switzerland Ltd.
