Manual UR67-Multiprotocol
2 Safety
This chapter includes general safety instructions on handling
the UR67 modules. Specific safety instructions for specific
tasks and situations are given at the appropriate places in
the documentation.
All work may only be carried out by trained
electricians who are familiar with the
safety standards that apply to automation
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 ongoing operations, the emergency
stop mechanisms must not be made ineffective.
If faults connected to a u-remote product cannot be rectified,
the product in question must be sent to Weidmüller. Wei-
dmüller 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. Only cables
and accessories that meet the requirements and provisions
regarding safety, electromagnetic compatibility and, if neces-
sary, telecommunications terminal equipment, as well as the
specifications, may be installed. Information on the specific
cables and accessories that are permitted to be installed is
provided in this manual or can be requested from Weidmül-
ler.
Electrostatic Discharge
u-remote products can be damaged or destroyed by electro-
static discharge. When handling the products, the neces-
sary safety measures against electrostatic discharge (ESD)
according to IEC 61340-5-1 and IEC 61340-5-2 must be
observed. The packing and unpacking as well as the installa-
tion and disassembly of a device may only be carried out by
qualified personnel.
Fusing
The operator must set up the equipment so that it is pro-
tected against overloading. The upstream fuse must be
designed so that it does not exceed the maximum load cur-
rent. The maximum permissible load current can be found
in the technical data. The operator must decide whether ad-
ditional surge protection is required according to IEC 62305.
Voltages that /-30 V may cause the destruction of
the modules. A power supply with secure isolation must be
used.
Earthing (functional earth FE)
Every UR67-MP module is equipped with an earth connec-
tion, with the connection point labelled “XE”. Further infor-
mation is available in chapters 5 and 6.
Shielding
Shielded lines are to be connected with shielded plugs in
compliance with the relevant standard (see chapter 6).
2.2 Intended use
The UR67-MP modules are decentral input and output de-
vices in an Ethernet/IP network or a PROFINET network.
The products are designed for use in industrial automa-
tion and may 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-volt-
age network. Additional measures must be taken for use in
the home, and in the business and commercial sectors.
Any intervention in the products hardware or software other
than described in this manual may only be realised by Wei-
dmüller.
Malfunction-free operation is only guaranteed if the housing
is fully assembled. Observance of the documentation is also
part of the intended use.
