Safety Notes!
Before starting the installation
Disconnect the power supply of the device.
Ensure that devices cannot be accidentally restarted.
Verify isolation from the supply.
Earth and short circuit.
Cover or enclose neighboring units that are live.
Follow the engineering instructions of the device concerned.
Only suitably qualified personnel in accordance with EN 50 110-
1/-2 (VDE 0 105 Part 100) may 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 equalization. The system installer is
responsible for implementing this connection.
Connecting cables and signal lines should be installed so that
inductive or capacitive interference do not impair the automation
functions.
Install automation devices and related operating elements in
such a way that they are well 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 auto-
mation devices.
Ensure a reliable electrical isolation of the low voltage for the 24
volt supply. Only use power supply units complying with IEC 60
364-4-41 (VDE 0 100 Part 410) or HD 384.4.41 S2.
Deviations of the mains voltage from the rated value must not
exceed the tolerance limits given in the specifications, otherwise
this may cause malfunction and dangerous operation.
Emergency stop devices complying with IEC/EN 60 204-1 must
be effective in all operating modes of the automation devices.
Unlatching the emergency-stop devices must not cause restart.

II
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, emergency-stop devices should be implemented.
Wherever faults in the automation system may cause damage to
persons or property, external measures must be implemented to
ensure a safe operating state in the event of a fault or malfunc-
tion (for example, by means of separate limit switches, mechan-
ical 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 and HD 384 and national work safety regulations).
All shrouds and doors must be kept closed during operation.
