5. Transport, packaging and storage
5.1 Transport
Check the air velocity transmitter for any damage that may have been
caused during transportation.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during
transport (e.g. change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +70 °C
Protect the instruments from moisture and dust.
6. Commissioning, operation
Installation and mechanical connection
The air velocity transmitter is installed in the duct. The cable for the
supply voltage and the cable for the relay connection (optional) have to
be laid separately, if high voltages (no safety extra-low voltage) are to be
switched with the relay. Both cables have their own cable entry.
The relay parameters have to be set before voltage is connected to the
relay connections. This ensures human safety against electric shock.
The instrument is equipped with a lid fixing screw. This screw has to
be used, if the voltage connected to the relay connections is no safety
extra-low voltage.
