Before starting with the installation
I
lInstallation requires qualified electrician
lDisconnect the power supply of the device.
lSecure against retriggering
lVerify isolation from the supply
lGround and short-circuit
lCover or enclose any
neighboring live parts.
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 equipotential bonding.
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 result in mal-
function and hazardous states.
lEmergency-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 result in an automatic restart.
lBuilt-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.
lMeasures should be taken to ensure the proper
restarting of programs interrupted after a voltage dip
or outage. This should not result in dangerous oper-
ating states even for a short time. If necessary, emer-
gency stop devices should be implemented.
lWherever faults in the automation system may
cause damage to persons or property, external meas-
ures must be implemented to ensure a safe oper-
ating state in the event of a fault or malfunction (for
example, by means of separate limit switches, mech-
anical interlocks, etc.).
DANGER!
