Caution!
Dangerous electrical voltage!
Before commencing the installation
● Disconnect the power supply of the device.
● Ensure that the device cannot be
accidentally restarted.
● Verify isolation from the supply.
● Earth and short circuit.
● Cover or enclose neighbouring units
that are live.
● Follow the engineering instructions (AWA)
ofthe device concerned.
● Only suitably qualified personnel may work
on this device/system.
● Before installation and before touching
thedevice ensure that you are free of
electrostatic charge.
● Connecting cables and signal lines should
be installed so that inductive or capacitive
interference do not impair the automation
functions.
● Install automation devices and related
operating elements in such a way that they
are well protected against unintentional
operation.
● Suitable safety hardware and software
measures should be implemented for the
I/Ointerface so that a line or wire breakage
on the signal side does not result in
undefined states in the automation devices.
● Ensure a reliable electrical isolation of the
low voltage for the 24 volt supply. Only use
power supply units complying with
IEC60364-4-41 or HD 384.4.41 S2.
● Deviations of the mains voltage from the
rated value must not exceed the tolerance
limits given in the specifications, otherwise
this may cause malfunction and dangerous
operation.
● Emergency stop devices complying with
IEC/EN 60 204-1 must be effective in all
operating modes of the automation devices.
Unlatching the emergency-stop devices
must not cause uncontrolled operation
orrestart.
● Devices that are designed for mounting in
housings or control cabinets must only be
operated and controlled after they have been
installed with the housing closed. Desktop
orportable units must only be operated and
controlled in enclosed housings.
● Measures should be taken to ensure the
proper restart of programs interrupted after
avoltage dip or failure. This should not
cause dangerous operating states even for
ashort time. If necessary, emergency-stop
devices should be implemented.
