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 bon-
ding. The system installer is responsible for imple-
menting this connection.
lConnecting cables and signal lines should be instal-
led so that inductive or capacitive interference
does not impair the automation functions.
lInstall automation devices and related operating
elements 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
result in undefined states in the automation devi-
ces.
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
switching off devices must not result in an auto-
matic 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
operating states even for a short time. If necessary,
emergency switching off devices should be imple-
mented.
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,
mechanical interlocks, etc.).
