Shielding
Shielded lines are to be connected with shielded plugs and
xed on a shield bus in compliance with the relevant stan-
dard (see Chapter10).
2.2 Intended use
The products of the u-remote series are intended for use in
industrial automation. A u-remote station with bus coupler
and connected modules is intended for the decentralised
control of systems or sub-systems. Via the eldbus bus cou-
pler every module of a station is integrated into a eldbus
structure and connected to the superordinate control unit.
The u-remote products conform to protection class IP 20 (in
accordance with DIN EN 60529), they can be used in poten-they can be used in poten-
tially explosive atmospheres rated as Zone 2 (as per Directive
94/9/EC) and in safe zones.
The observance of the supplied documentation is part of the
intended use. The products described in this manual may
only be used for the intended applications and only in con-
nection with certied third-party devices or components.
2.3 Legalnotice
The u-remote series products are CE-compliant in accor-
dance with Directive 2004/108/EC (EMC Directive) and
Directive 2006/95/EC (Low Voltage Directive). They also
meet the requirements of the ATEX Directive 94/9/EG.

2.4 Use in a potentially explosive atmosphere
If u-remote products are used in potentially explosive atmos-
pheres, the following notes are also applicable:
– Staff involved in assembly, installation and operation must
be qualified to perform safe work on electrical systems
protected against potentially explosive atmospheres.
– For applications in potentially explosive atmospheres, the
requirements according to DINEN60079-15 must be
observed, in particular the housing enclosing the system
must meet the requirements of explosion protection type
Exn or Exe and protection class IP54.
– Sensors and actuators that are located in Zone 2 or in a
safe zone can be connected to the u-remote station.
– When the temperature under rated conditions exceeds
70 °C at the conductor or conduit entry point, or 80 °C at
the contact, the temperature specification of the selected
cable shall be in compliance with the actual measured
temperature values.
– When using relais modules UR20-4RO-CO-255 in explo-
sive atmosphere:
– Condensation shall be avoided.
– If the switching voltage exceeds 63V, a surge protec-
tion device shall be provided that limits the transients
to a peak voltage of 500V or less.
– A visual inspection of the u-remote station is to be per-
formed once per year.
