2 Safety
This section includes general safety instructions for handling
the u-remote IP67 modules. Specic safety instructions for
specic tasks and situations are given at the appropriate
places in the documentation.
Work on the u-remote products may only
be performed by qualied electricians that
are familiar with the safety standards in au-
tomation technology.
The documentation should be stored in a
way that it is accessible for the personnel
at any time.
2.1 General safety notice
When working during continued operations, the emergency
stop mechanisms must not be made ineffective.
If a malfunction on a u-remote product cannot be xed after
following the recommended measures (see Chapter9), the
product in question must be sent back to Weidmüller. Wei-
dmüller does not assume any liability if the base or electronic
module has been tampered with!
All connected devices have to fulll the requirements of
EN61558-2-4 and EN61558-2-6. Only lines and accesso-
ries may be installed that fulll the requirements and rules
für safety, electromagnetic compatibility and telecommuni-
cation devices as well as the specications. All information
about approved lines and accessories are provided in this
manual or available from Weidmüller.
Electrostatic discharge
u-remote products can be damaged or destroyed by electro-
static discharge. When handling the products, the necessary
safety measures against electrostatic discharge (ESD) ac-
cording to IEC61340-5-1 and IEC61340-5-2 must be ob-
served. The packing and unpacking as well as the installation
and disassembly of a device may only be carried out by quali-
ed personnel and in accordance with the ESD information.
Fusing
The operator must set up the equipment so that it is protect-
ed against overloading. The upstream fuse must be designed
such that it does not exceed the maximum load current. The
maximum permissible load current of the u-remote compo-
nents can be found in the technical data.
The operator has to decide whether additional overvoltage
protection according to IEC62305 is required. Voltages that
exceed +/-30V may cause the destruction of the modules. A
power supply with protective separation has to be used for
power feed-in.
Earthing (functional earth FE)
Each IP67 remote-I/O module is provided with an earthing
connection. On the metall modules the connection point is
indicated as „XE“. When using the modules made from plas-
tics the earthing clamp has to be connected.
Further information are provided in Chapter6 „Earthing and
shielding“.
Shielding
Shielded lines are to be connected with shielded plugs in
compliance with the relevant standard (see Chapter6).
2.2 Intended use
The UR67 PROFIBUS-I/O modules are intended for use as de-
centralised input and output devices within a PROFIBUS-DP
network in industrial automation. The products may only be
used within the described technical specication.
The devices to be connected must fulll the requirements ac-
cording to EN61558-2-4 and EN61558-2-6.
The industrial environment is characterised by the fact that
appliances are not connected directly with the public low
voltage system. Special measurements have to be taken for
the use in residential areas, business or trade areas.
Any intervention in the products hard or software other than
described in this manual may only be realised by Weidmüller.
Undisturbed operation is only be guaranteed with the hous-
ings completely closed. The observance of the documenta-
tion is part of the intended use.
2.3 Legal notice
The u-remote IP67 series products are CE-compliant in ac-
cordance with Directive 2014/30/EU (EMC Directive).
Components of the following free software products are inte-
grated into the u-remote products:
