WARNING
• Do not touch the heat sink of the frequency inverter during operation. Danger of burns due to
high surface temperatures.
• Do not remove any covers of the frequency inverter during operation.
• Please note that Bonfiglioli Vectron will not accept any responsibility for compatibility with third-
party products (e.g. motors, cables, filters, etc.). If you use the device in combination with third-
party products, you do so at your own risk.
• The earth leakage current of the frequency inverter may exceed AC 3.5 mA or DC 10 mA.
• Please note (according to EN61800-5-1): This product may cause direct current in the protective
earth conductor. Where residual current devices (RCD) or residual current monitors (RCM) are
GB
used as a protection against direct or indirect contact, only RCDs / RCMs of Type B are permissib-
le on the power supply side of this product.
• Do not touch electronic components or contacts.
• Defective components must not be put into operation.
• Any repair work may only be carried out by the manufacturer or persons approved/licensed by
the manufacturer.
• Any repair work must be carried out by qualified electricians.
• Except for modifications described in this document, the frequency inverter must not be changed
in any way.
• Do not connect inappropriate voltage sources.
• Keep the instructions accessible to the user.
NOTE
The frequency inverter may be connected to power supply every 60 s.
This must be considered when operating a mains contactor in jog operation mode. For commission-
ing or after an emergency stop, a non-recurrent, direct restart is permissible.
NOTE
For more information about the range of functions of the frequency inverter and about operation,
maintenance and storage, refer to the co-applicable Operating Instructions.

Designated use
The product is a frequency inverter. It is designed for
installation in machines and electrical equipment
•
industrial environments
•
The frequency inverters are electrical drive components intended for stationary installation in electrical cabinets of
industrial plants or machines. They may only be used for driving asynchronous three-phase squirrel cage motors or
permanently excited three-phase synchronous motors which are designed for operation with frequency inverters.
Where built-in motor temperature sensors are evaluated via the frequency inverter, a double/reinforced insulation
of the temperature sensor against the motor winding must be provided according to DIN EN 61800-5-1.
Commissioning and start of operation is not allowed until it has been verified that the machine meets the require-
ments of the EC Machinery Directive 2006/42/EC and DIN EN 60204-1.
The frequency inverters meet the requirements of the low voltage directive 2006/95/EEC and DIN EN 61800-5-1.
CE-labeling is based on these standards. Responsibility for compliance with the EMC Directive 2004/108/EC lies
with the operator.
Frequency inverters are only available at specialized dealers and are exclusively intended for commercial use as per
EN 61000-3-2.
No capacitive loads may be connected to the frequency inverter.
