Before starting with the installation
•
De-energize the device
•
Secure against retriggering
•
Verify isolation from the supply
•
Ground and short-circuit
•
Cover or enclose any neighboring live parts
•
Follow the mounting instructions (AWA/IL) for the device
•
Only suitably qualified personnel in accordance with
EN 50 110-1/-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 equipotential bonding.
The system installer is responsible for implementing
this connection
•
Connecting cables and signal lines should be installed in
such a way that inductive and capacitive interference will
not have a negative impact on 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 cable or wire
breakage on the signal side will not result in undefined
states in the automation devices
•
Ensure a reliable electrical isolation of the low voltage
for the 24 V supply; only use power supply units
complying with IEC 60364-4-41 or HD 384.4.41 S2
(VDE 0100 Part 410)
•
Deviations of the mains voltage from the nominal
value must not exceed the tolerance limits given in the
specifications, otherwise this may result in malfunction
and hazardous states
•
Emergency stop devices complying with IEC/EN 60204-1
must remain functional in all of the automation devices’
operating modes; unlatching the emergency stop devices
must not result in an automatic restart
•
Built-in devices for enclosures or cabinets must only be
run and operated in an installed state; desktop devices
and portable devices only when the housing is closed
•
Measures should be taken to ensure the proper restarting
of programs interrupted after a voltage dip or outage. This
should not result in 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.)
