1 Notes
To protect the instrument from electrostatic discharge,
users must discharge themselves electrostatically before
touching the instrument !
All necessary settings are described in these
Operating Instructions. However, if any difficulties
should still arise during start-up, please do not carry
out any manipulations on the unit. You could
endanger your rights under the instrument warranty!
Please contact the nearest subsidiary or the head
office in such a case.
Please read these operating instructions before
starting up the instrument. Keep the manual in a place
which is accessible to all users at all times. Please
assist us to improve these operating instructions,
where necessary.

2 Identifying the device version
The nameplate with the order code is glued to the side of the
housing. The supply voltage must correspond to the voltage given
on the nameplate.

4 Electrical connection
The choice of cable, the installation, the fusing and the electrical
connection must conform to the requirements of VDE 0100
“Regulations on the Installation of Power Circuits with Nominal
Voltages below 1000 V” or the appropriate local regulations.
❏To protect the instrument from electrostatic discharge, users
must discharge themselves electrostatically before touching the
instrument!
❏The electrical connection must only be carried out by qualified
personnel.
❏Electromagnetic compatibility conforms to the standards and
regulations cited in the technical data.
❏The instrument is not suitable for use in areas with an explosion
hazard (Ex areas).
Apart from faulty installation, incorrect settings on the instrument
may also affect the proper functioning of the subsequent process or

lead to damage. Safety devices should always be provided that are
independent of the instrument (such as overpressure valves or
temperature monitors/limiters) and only capable of adjustment by
specialist personnel. Please observe the relevant safety regulations
for such matters.
❏The load circuit must be fused for the maximum relay current, in
order to prevent the output relay contacts becoming welded in
the event of a short circuit.
❏Do not connect any additional loads to the screw terminals for
the supply of the instrument.
❏Any electrical connection other than that specified in the
connection diagram may result in the destruction of the
instrument.
❏Run input, output and supply cables separately and not parallel
to one another.
❏Sensor leads must only be implemented as twisted and
shielded, uninterrupted cables (not routed via terminal blocks
etc).
❏Supply fluctuations are only permissible within the specified
tolerances (see Data Sheet 20.2731, page 3/6).
