Before commencing the installation
I
lInstallation, electrotechnical expertise
lDisconnect the power supply of the device.
lEnsure that devices cannot be accidentally ret-
riggered
lVerify isolation from the supply
lGround and short-circuit.
lCover or enclose neighbouring units that are live.
lFollow the engineering instructions (IL) of the device
concerned.
lOnly suitably qualified personnel in accordance with
EN 50110-1/-2 (VDE 0105 part 100) may work on this
device/system.
lBefore installation and before touching the device
ensure that you are free of electrostatic charge.
lThe 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.
lConnecting cables and signal lines should be installed
so that inductive or capacitive interference does not
impair the automation functions.
lInstall automation devices and related operating ele-
ments in such a way that they are well protected
against unintentional operation.
lSuitable 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.
lDeviations 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.
lEmergency-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.
lBuilt-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.
lMeasures 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.
lWherever 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.).
