Before starting with the installation
• Disconnect the power supply of the device.
• Secure against retriggering
• Verify isolation from the supply
• Ground and short-circuit
• Cover or enclose neighbouring units that are live.
• Follow the mounting instructions (AWA/IL) for the device.
• 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 equipotential bonding. The
system installer is responsible for implementing this
connection.
• Connecting cables and signal lines should be installed in
such a way that inductive and capacitive interference will
not have a negative impact on 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 cable or wire
breakage on the signal side will 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
specifications, otherwise this may result in malfunction
and hazardous states.
• Emergency stop devices complying with IEC/EN 60204-1
must remain functional in all of the automation devices'
operating modes. Unlatching the emergency stop devices
must not result in an automatic restart.
• Built-in devices for enclosures or cabinets must only be
run and operated in an installed state; desktop devices
and portable devices only when the housing is closed.
• Measures should be taken to ensure the proper restarting
of programs interrupted after a voltage dip or outage. This
should not result in 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 malfunction (for example, by means of
separate limit switches, mechanical interlocks, etc.).
