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