3. Installation
The sensor can be installed directly in the hydraulic system via the threaded connection. It is
recommended that the sensor is mounted vertically with the electrical connector pointing
downwards. When fitting, ensure that the sensor is completely submerged in the fluid and that the
fluid can circulate freely around the sensor.
HYDAC ELECTRONIC provides appropriate installation accessories for installing the HYDACLab
®
(see Section 11.1, Accessories, Mechanical).
The electrical connection must be carried out by a qualified electrician according to the relevant
regulations of the country concerned (VDE 0100 in Germany).
HYDACLab
® Sensors carry the CE mark. A certificate of conformity will be provided on request .
EMC standards: EN 61000-6-1, EN 61000-6-2, EN 61000-6-3 and EN 61000-6-4 have all been
met. However, the stipulations of those standards will be met only if the sensor’s housing has been
correctly earthed by a qualified electrician. When fitted into a hydraulic block, it is sufficient if the
block is earthed via the hydraulic system.
Additional installation instructions that, from experience, reduce the effect of electromagnetic
interference are:
• Keep line connections as short as possible.
• Use screened wires, such as LIYCY 5 x 0.5 mm², only.
• The cable screening 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 of power equipment, as well as from
any electrical or electronic equipment causing interference.
