The recommended mounting position
is vertical with the pressure connection pointing upwards in hydraulic
applications,
and vertical with the pressure connection pointing downwards in pneumatic
applications.
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 conformity declaration 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 fitted into
a hydraulic block, earthing the block via the hydraulic system is sufficient. When using
hose mounting the housing has to be grounded separately.
6.2 Additional installation instructions
Additional installation instructions 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 shielding must be fitted by qualified personnel, subject to the environmental
conditions and with the aim of suppressing interference.
Keep the instrument well away from the electrical supply lines of power equipment, as
well as from any electrical or electronic equipment causing interference.
