Before commencing 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 neighbouring units that
are live.
• Follow the engineering instructions (AWA)
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
equalisation. The system installer is responsible
for implementing this connection.
• Connecting cables and signal lines should be
installed so that inductive or capacitive
interference does 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 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.
• 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
malfunction (for example, by means of separate
limit switches, mechanical interlocks etc.).
