I
Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally retriggered
• Verify isolation from the supply
• Earth and short-circuit
• Cover or enclose neighbouring units that are live.
• Follow the engineering instructions (AWA/IL) of the device
concerned.
• Only suitably qualified personnel in accordance with EN
50 110-1/-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) 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 actuation.
• 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 supply units complying
with IEC 60 364-4-41 (VDE 0100 Part 410) or HD 384.4.41 S2.
• 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 switching off devices complying with IEC/EN
60 204-1 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.).
