Notes
Security
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
●Observe national provisions and comply with the appropriate safety regulations.
●Use only properly trained technicians for mounting, commissioning and servicing.
Engineering
Identification
Each device has a unique serial number to ensure efficient commissioning. It is provided on
the adhesive barcode reader. The serial number can be read directly into the engineering
tool using a barcode reader.
Wiring
Wiring must be sufficiently insulated to the available rated voltage. Sizing and fusing of the
wiring depends on the connected load.
Mounting
The automation station is mounted directly on a damper shaft.
