Safety

This chapter includes general safety instructions on handling
the u-remote IP67 modules. Specific safety instructions for
specific tasks and situations are given at the appropriate
places in the documentation.
All work must only be carried out by
trained electricians who are familiar with
the safety standards that apply to automa-
tion technology.
The documentation must be stored in such a
way that it is accessible to operating staff at
all times.
2.1

General safety notice

When working during continued operations, the emergency
stop mechanisms must not be made ineffective.
If faults relating to a u-remote product cannot be rectified,
the product in question must be sent to Weidmüller. Weid-
müller assumes no liability if the module is tampered with!
All connected devices must comply with the requirements
set out in EN 61558-2-4 and EN 61558-2-6. Cables and ac-
cessories may only be installed if they meet the requirements
and provisions regarding safety, electromagnetic compati-
bility and, if applicable, telecommunications terminal equip-
ment, as well as the relevant specifications. Information on
the specific cables and accessories that are permissible for
installation is provided in this manual or can be requested
from Weidmüller.
Electrostatic discharge
u-remote products can be damaged or destroyed by electro-
static discharge. During handling of the products, the neces-
sary safety measures against electrostatic discharge (ESD)
must be observed in accordance with IEC 61340-5-1 and
IEC 61340-5-2. The packing and unpacking as well as the
assembly and disassembly of a device must only be carried
out by qualified personnel.
Fusing
The operator must set up the equipment so that it is pro-
tected against overloading. The 24 V DC power supply units
used for supplying the system must fulfill the SELV category.
The upstream fuse must be designed such that it does not
exceed the maximum load current. The maximum permissi-
ble load current for the u-remote components can be found
in the technical data.
The operator must decide whether additional surge protec-
tion is required in accordance with IEC 62305. Voltages that
2599890000/01/03.2020
exceed +/-30 V may lead to the destruction of the modules.
A power supply with secure isolation must be used.
Earthing (functional earth FE)
Each UR67-PN-V14 module has two earthing connections;
the connection points are labelled with "XE". More informa-
tion can be found in chapter 5.
Shielding
Shielded lines are to be connected with shielded plugs in
compliance with the relevant standard.
2.2 Intended use
The UR67-PN-V14 modules are decentralised input and out-
put devices within a PROFINET network (RT/IRT).
The products are designed for use in an industrial environ-
ment and must only be used within the scope of the stated
technical specifications. The devices to be connected must
comply with the requirements set out in EN 61558-2-4 and
EN 61558-2-6. The industrial environment is labelled as
such to ensure that consumers are not directly connected to
the public low-voltage network. Additional measures must
be taken for use in the home, and in the business and com-
mercial sectors.
Any intervention in the products' hardware or software other
than described in this manual may only be performed by
Weidmüller.
Malfunction-free operation is only guaranteed if the housing
is fully assembled. Observance of the documentation is also
part of the intended use.
2.3

Legal notice

The UR67-series products comply with the EU Directive
2014/30/EU (EMC Directive).
Components of free software products are integrated into
the modules: The licence terms are available from the web
server.
