I
Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally retriggered
• Verify isolation from the supply
• Ground and short-circuit.
• Cover or enclose neighbouring units that are live.
• Follow the engineering instructions (IL) of the device
concerned.
• Only suitably qualified personnel in accordance with EN
50110-1/-2 (VDE 0105 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, PES) must be connected to the
protective earth (PE) or to the potential equalizing. 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 automation devices.
• Ensure a reliable electrical isolation of the low voltage for the
24 V supply. Only use power supply units complying with
IEC 60364-4-41 or HD 384.4.41 S2 (VDE 0100 part 410).
• Deviations of the mains voltage from the nominal value must
not exceed the tolerance limits given in the technical data,
otherwise this may cause malfunction and dangerous
operation.
• Emergency-Stop devices complying with IEC/EN 60204-1 must
be effective in all operating modes of the automation devices.
Unlatching the emergency switching off devices must not
cause restart.
• Built-in devices for enclosures or cabinets must only be run and
operated in an installed state, desk-top devices or portable
devices only when the housing is closed.
• 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 switching off 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 malfunction (for example, by means of separate limit
switches, mechanical interlocks, etc.).
