Warnings
The components of the power unit of the frequency converter are live when it is connected
to mains. Coming into contact with this voltage is extremely dangerous and may cause
death or severe injury. The control unit is isolated from the mains potential.
The motor terminals U, V, W are live when the frequency converter is connected to mains,
even if the motor is not running.
The control I / O terminals are isolated from the mains potential. However, the relay
output terminals may have a dangerous control voltage present even when the frequency
converter is disconnected from mains.
The earth leakage current of the frequency converters can exceed 3.5 mA AC. According to
standard EN61800-5-1, a reinforced protective ground connection must be ensured.
If the frequency converter is used as part of a machine, the machine manufacturer is
responsible for providing the machine with a main switch (EN 60204-1).
If the frequency converter is disconnected from mains while running the motor, it remains
live if the motor is energized by the process. In this case the motor functions as a generator
feeding energy to the frequency converter.
After disconnecting the frequency converter from mains, wait 5 more minutes before doing
any work on frequency converter connections.
The motor can start automatically after a fault situation, if the autoreset function has been
activated.
In a domestic environment this product may cause radio interference in which case
supplementary mitigation measures may be required.
Intended for use in first environment, that includes domestic premises, it also includes
establishments directly connected without intermediate transformers to a low-voltage
power supply network which supplies buildings used for domestic purpose.
Note! The frequency converter is only EMC compliant when supplied in IP54 model. If the
frequency converter is supplied in IP00 model, the customer will be responsible for EMC
compliance.
The frequency converter is sensitive to ESD (ElectroStatic Discharge). Handle with care. ESD
can cause damage to the frequency converter
