Warning!
Dangerous electrical voltage!
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 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.

• 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.).
