Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally
restarted.
• Verify isolation from the supply.
• Short circuit to earth.
• Cover or enclose neighboring 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 equalization. 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.
