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.
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.
