DANGER!
Dangerous Electrical Voltage!
Before commencing the installation
Installation, electrotechnical expertise
l
Disconnect the power supply of the device.
l
Ensure that devices cannot be accidentally ret-
l
riggered
Verify isolation from the supply
l
Ground and short-circuit.
l
Cover or enclose neighbouring units that are live.
l
Follow the engineering instructions (IL) of the device
l
concerned.
Only suitably qualified personnel in accordance with
l
EN 50110-1/-2 (VDE 0105 part 100) may work on this
device/system.
Before installation and before touching the device
l
ensure that you are free of electrostatic charge.
The functional earth (FE) must be connected to the
l
protective earth (PE) or to the potential equalizing. The
system installer is responsible for implementing this
connection.
Connecting cables and signal lines should be installed
l
so that inductive or capacitive interference does not
impair the automation functions.
Install automation devices and related operating ele-
l
ments in such a way that they are well protected
against unintentional operation.
Suitable safety hardware and software measures
l
should be implemented for the I/O interface so that a
line or wire breakage on the signal side does not res-
ult in undefined states in the automation devices.
Deviations of the mains voltage from the nominal
l
value must not exceed the tolerance limits given in
the specifications, otherwise this may cause mal-
function and dangerous operation.
Emergency-Stop devices complying with IEC/EN
l
60204-1 must be effective in all operating modes of
the automation devices. Unlatching the emergency
switching off devices must not cause restart.
Built-in devices for enclosures or cabinets must only
l
be run and operated in an installed state, desk-top
devices or portable devices only when the housing is
closed.
Measures should be taken to ensure the proper
l
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
switching off devices should be implemented.
Wherever faults in the automation system may cause
l
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, mech-
anical interlocks, etc.).
