5 Installation
The pressure switch can be mounted directly to the hydraulic system via the thread
connection. In order to prevent mechanical damage when dealing with critical applications
involving heavy vibrations or blows, for example, we recommend securing the unit with an
elastomer clamp and decoupling the hydraulic ports via a Minimess hose. The
recommended mounting position is vertical with the pressure connection pointing upwards
in hydraulic applications, in pneumatic applications, the pressure connection must point
downwards. The electrical connection must be carried out by a qualified electrician
according to the relevant regulations of the country concerned (VDE 0100 in Germany).
EDS 820 pressure switches are
marked. A certificate of conformity is available on
request. The relevant EMC standards EN 61000-6-1; EN 61000-6-2, EN 61000-6-3,
EN 6100-6-4 are 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 installed in a
hydraulic block, earthing the block via the hydraulic system is sufficient. When using hose
mounting the housing has to be grounded separately.
Additional installation suggestions which, from experience, reduce the effect of
electromagnetic interference:
•
Make line connections as short as possible
•
Connection with unscreened standard sensor line possible up to a max. line length
of 20 m.
•
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 lines of power equipment, as well as
from any electrical or electronic equipment causing interference.
