Correct use
The UE4155 bus node must be used only as defined in chapter 2.2 “Applications of the
device”. It must be used only by qualified personnel and only on the machine/system
where it has been installed and initialised by qualified safety personnel in accordance with
these operating instructions.
If the device is used for any other purposes or modified in any way — also during mounting
and installation — any warranty claim against SICK AG shall become void.

General safety notes and protective measures
Pay attention to the safety notes!
Please observe the following procedures in order to ensure the correct and safe use of the
UE4155 bus node.
The national/international legislative provisions apply to the installation and use of the
bus node and the safety components connected to it, e.g. a safety light curtain or com-
ponents fitted with contacts; these legislative provisions apply also to the commission-
ing and recurring technical examinations, in particular:
– Machine Directive 2006/42/EC
– EMC Directive 2004/108/EC
– Work Equipment Directive 89/655/EEC
– the work safety regulations/safety rules
– other relevant health and safety regulations
Manufacturers and operators of the machine with which the bus node is used are
responsible for obtaining and observing all applicable safety regulations and rules.
The notes in these operating instructions (e.g. on use, mounting, installation or inte-
gration into the existing machine controller) must be observed.
The test procedures in the operating instructions of all connected components must be
observed.
Changes to the configuration of the devices can degrade the protective function. After
every change to the configuration you must therefore check the effectiveness of the pro-
tective device.
The person who makes the change is also responsible for the correct protective function
of the device. When making configuration changes, please always use the password
hierarchy provided by SICK to ensure that only authorised persons make changes to the
configuration. The SICK service team is available to provide assistance if required.
The tests must be carried out by specialist safety personnel or specially qualified and
authorised personnel and must be recorded and documented to ensure that the tests
can be reconstructed and retraced at any time.
The operating instructions must be made available to the operator of the machine
where the UE4155 bus node is fitted.
The external voltage supply of the device must be capable of buffering brief mains
voltage failures of 20 ms as specified in EN 60 204.
When using the bus node in accordance with the requirements in UL 508, the power
supply must permit “use in class-2 circuits”. No current may be allowed to flow that is
> 8 A.
