Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally restarted.
• Verify isolation from the supply.
• Earth and short circuit the device.
• Cover or enclose any adjacent live components.
• Follow the engineering instructions (IL04020001E) for the
device concerned.
• Only suitably qualified personnel in accordance with
EN 50110-1/-2 (VDE 0105 Part 100) may work on this
device/system.
• Before installation and before touching the device ensure
that you are free of electrostatic charge.
• The functional earth (FE, PES) must be connected to the
protective earth (PE) or the potential equalisation. The system
installer is responsible for implementing this connection.
• Connecting cables and signal lines should be installed so
that inductive or capacitive interference does 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/O interface so that an open circuit on the
signal side does not result in undefined states in the
automation devices.
• Ensure a reliable electrical isolation of the extra-low voltage of
the 24 V supply. Only use power supply units complying with
IEC 60364-4-41 (VDE 0100 Part 410) or HD384.4.41 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 60204-1 must
be effective in all operating modes of the automation devices.
Unlatching the emergency-stop devices must not cause a
restart.
• Devices that are designed for mounting in housings or control
cabinets must only be operated and controlled after they have
been installed and with the housing closed. Desktop or
portable units must only be operated and controlled in
enclosed housings.
• 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.
• Wherever faults in the automation system may cause injury or
material damage, 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.).
• Depending on their degree of protection, adjustable frequency
drives may contain live bright metal parts, moving or rotating
components or hot surfaces during and immediately after
operation.
• Removal of the required covers, improper installation or
incorrect operation of motor or adjustable frequency drive may
cause the failure of the device and may lead to serious injury or
damage.
• The applicable national accident prevention and safety
regulations apply to all work carried on live adjustable
frequency drives.
• The electrical installation must be carried out in accordance
with the relevant regulations (e. g. with regard to cable cross
sections, fuses, PE).
• Transport, installation, commissioning and maintenance work
must be carried out only by qualified personnel (IEC 60364,
HD 384 and national occupational safety regulations).
• Installations containing adjustable frequency drives must be
provided with additional monitoring and protective devices in
accordance with the applicable safety regulations.
Modifications to the adjustable frequency drives using the
operating software are permitted.
