Danger!
Dangerous electrical voltage!
Before commencing the installation
• Disconnect the power supply of the device.
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.).
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.
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.
Follow the engineering instructions (IL04020001E) for the
device concerned.
Only suitably qualified personnel in accordance with
EN 50110-1/-2 (VDE 0 105 Part 100) may work on this
device/system.
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.
Before installation and before touching the device ensure
that you are free of electrostatic charge.
The applicable national accident prevention and safety
regulations apply to all work carried on live adjustable
frequency drives.
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.
The electrical installation must be carried out in accordance
with the relevant regulations (e. g. with regard to cable cross
sections, fuses, PE).
Connecting cables and signal lines should be installed so
that inductive or capacitive interference does not impair the
automation functions.
Transport, installation, commissioning and maintenance work
must be carried out only by qualified personnel (IEC 60364,
HD 384 and national occupational safety regulations).
Install automation devices and related operating elements in
such a way that they are well protected against unintentional
operation.
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.
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 60 364-4-41 (VDE 0 100 Part 410) or HD384.4.41 S2.
All covers and doors must be kept closed during operation.
To reduce the hazards for people or equipment, the user must
include in the machine design measures that restrict the
consequences of a malfunction or failure of the drive
(increased motor speed or sudden standstill of motor).
These measures include:
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.
– Other independent devices for monitoring safety-related
variables (speed, travel, end positions etc.).
– Electrical or non-electrical system-wide measures
(electrical or mechanical interlocks).
– Never touch live parts or cable connections of the adjustable
frequency drive after it has been disconnected from the
power supply. Due to the charge in the capacitors, these
parts may still be live after disconnection. Fit appropriate
warning signs.
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.
