•The unit must be installed according to the instructions.
•The information on the type code label must be noted.
•Troubleshooting and repair work may only be carried out at the HYDAC Service
Department.
•All relevant and generally recognised safety requirements must be adhered to.
•If the instrument is not handled correctly, or if the operating instructions and specifications

3 Installation
The sensor can be installed directly in the hydraulic system via the threaded connection.
For hydraulic applications the recommended mounting position is vertical with the
mechanical connection pointing upwards. When installing, ensure that the sensor is fully
submerged in the fluid and that the fluid can circulate freely around the sensor. For tank
installation therefore, the sensor should be sited only where turbulence is known to occur.
The electrical connection must be carried out by a qualified electrician according to the
relevant regulations of the country concerned (VDE 0100 in Germany).
The sensors of the AS 1000 series carry the CE mark. A certificate of conformity is
available on request. EMC standards: Compliant with EN 61000-6-1, EN 61000-6-2,
EN 61000-6-3 and EN 61000-6-4. However, the stipulations of those standards are met
only if the sensor's housing has been correctly earthed by a qualified electrician. When
installed in a hydraulic block, earthing the block via the hydraulic system is sufficient.
Additional installation suggestions which, from experience, reduce the effect of
electromagnetic interference:
•Make line connections as short as possible.
•Use shielded cabling (e.g. LIYCY 5 x 0.5 mm²).
•The cable shielding must be fitted by qualified personnel, subject to the ambient
conditions and with the aim of suppressing interference.
•Keep the unit well away from the electrical supply lines of power equipment, as well as
from any electrical or electronic equipment causing interference.
