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 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 IP20 (in
accordance with DIN EN 60529), 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 certied third-party devices or components.
2.3 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.
– The requirements according to IEC 60079-15 must be
observed.
– The housing enclosing must be ATEX/IECEx certified
meeting the requirements of protection class IP54, acces-
sible only by use of a tool.
– The housing enclosing must meet the requirements of
explosion protection type Exn or Exe.
– Sensors and actuators that are located in Zone 2 or in a
safe zone can be connected to the u-remote station.
– If the ambient temperature under rated conditions exeeds
55°C, the cables used for feed-in (on the fieldbus coupler
and on power-feed modules) must be specified for at
least 90°C.
– If 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.
– Devices are for use in an area of not more than pollution
degree 2 in accordance with EN60664-1.
– When using relais modules UR20-4RO-CO-255 in explo-
sive atmosphere:
– Condensation has to be avoided.
– Provision shall also be made to prevent the relay circuit
voltage from being exceeded by transient disturbances
of more than 140% of the rated voltage.
– A visual inspection of the u-remote station is to be per-
formed once per year.
2.4 Legal notice
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.

The results of the measurements according to CISPR 16-3-
2 should also be suitable to demonstrate the compliance
of the u-remote devices to the limits for radiated emissions
as dened by CFR 47 Part 15, Subpart B, §15.109, Class A
(2010) and ICES-003, Issue 5, Class A (2012).
