2 Safety instructions
These instructions contain texts and figures concerning the correct handling of the
device and must be read before installation or use�
Observe the operating instructions� Non-observance of the instructions, operation
which is not in accordance with use as prescribed below, wrong installation or
incorrect handling can seriously affect the safety of operators and machinery�
►Prepare installation
►Disconnect the power supply of the device�
►Ensure that devices cannot be accidentally restarted�
►Verify safe isolation from the supply�
►Earth and short circuit�
►Cover or enclose adjacent units that are live�
►Follow the specific mounting instructions of the device�
►Only suitably qualified personnel in accordance with EN 50 110-1/-2
(VDC 0105 part 100) is permitted to work on this device/system�
►Before installation and before touching the device ensure that you are free of
electrostatic charge�
►The functional earth (FE) must be connected to the protective earth (PE) or to
the potential equalisation� The system installer is responsible for implementing
this connection�
►Connecting cables and signal lines must be installed in such a manner that
inductive or capacitive interference do not impair the automatic functions�
►Install automation equipment and related operating elements in such a way that
they are protected against unintentional operation�
►Suitable safety hardware and software measures should be implemented for
the I/O interface so that a line or wire breakage on the signal side does not
result in undefined states in the automation device�
►Ensure a reliable electrical isolation of the low voltage for the 24 V supply�
Only use power supplies compliant with IEC 60 364-4-41 or HD 384�4�41 S2
(VDE 0100 part 410)�
►Fluctuations or deviations of the mains voltage from the rated value must not
exceed the tolerance limits specified in the technical data; otherwise this may
cause malfunction and dangerous operation�
►E-stop devices to IEC/EN 60 204-1 must be effective in all operating modes of
the automation device� Unlatching the e-stop devices must not cause restart�

IO-Link master

►Devices that are designed for mounting in housings or control cabinets must
only be operated and controlled after they have been installed with the housing
closed� Desktop or portable units must only be operated and controlled in
enclosed housings�
►Measures should be taken to ensure the proper restart of programs interrupted
after a voltage dip or failure� This should not cause dangerous operating states
even for a short time� If necessary, an emergency stop must be carried out�
►Wherever faults in the automation system may cause personal injuries or
damage to property, external measures must be implemented to ensure a safe
operating state in the event of a fault or malfunction (e�g� by means of separate
limit switches, mechanical interlocks etc�)
►The electrical installation must be carried out in accordance with the relevant
regulations (e�g� with regard to cable cross-sections, fuses, PE)�
►All work relating to transport, installation, commissioning and maintenance
must only be carried out by qualified personnel� (IEC 60 364 or HD 384 or
DIN VDE 0100 and national work safety regulations have to be observed)�
►All shrouds and doors must be kept closed during operation�
