If the frequency converter is connected to an installation with a residual current device as an extra
protection, the device must be marked with the following symbol: HPFI/PFI
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 (connection 1-15) is isolated from the mains potential.
The motor terminals U, V and W are live when the frequency converter is connected to
mains, even when the motor is not running.
The control I / O terminals are isolated from the mains potential (clamps 1 – 15). However,
dangerous control voltage may be present at the relay output terminals (9, 10 and 11) even
when the frequency converter is disconnected from mains.
The earth leakage current may exceed 3.5 mA AC when the frequency converter is
connected to a motor. According to standard EN61800-5-1 a reinforced protective ground
connection must be mounted.
If the frequency converter is part of a machine solution, the machine manufacturer is
responsible for providing the machine with a main switch. (EN60204-1).
If the frequency converter is disconnected from mains while the motor is running, high and
dangerous voltage may still be present on the frequency converter power unit. In this case
the motor is operating as a generator supplying the frequency converter with power.
After disconnecting the frequency converter from mains, wait a minimum of 5 minutes
before handling the frequency converter.
The frequency converter may automatically start the motor after a fault situation or after
reconnection of mains. Note that there might be a minimum downtime during which the
motor cannot be stopped.
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
may cause damage to the frequency converter.
