Warning!
Dangerous electrical voltage!
Before commencing the installation
• Disconnect the power supply of the device.
• Ensure a reliable electrical isolation of the low voltage for the
24 volt supply. Only use power supply units complying with
IEC 60 364-4-41 (VDE 0 100 Part 410) or HD 384.4.41 S2.
• Ensure that devices cannot be accidentally restarted.
• Verify isolation from the supply.
• 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.
• Earth and short circuit.
• Cover or enclose neighbouring units that are live.
• Follow the engineering instructions (AWA) of the
device concerned.
• 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 restart.
• Only suitably qualified personnel in accordance with
EN 50110-1/-2 (VDE 0105 Part 100) may work on
this device/system.
• 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 or portable
units must only be operated and controlled in enclosed
housings.
• Before installation and before touching the device ensure
that you are free of electrostatic charge.
• The functional earth (FE) must be connected to the protective
earth (PE) or to the potential equalisation. The system installer
is responsible for implementing this connection.
• 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-stop devices should be implemented.
• Connecting cables and signal lines should be installed so
that inductive or capacitive interference does not impair the
automation functions.
• 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, mechanical interlocks etc.).
• 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/O interface so that a line or wire
breakage on the signal side does not result in undefined
states in the automation devices.
