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
IL (previously AWA) 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) 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 60364-4-
41 (VDE 0100 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 60204-1 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.
