Quick
Setup
3. Correct protective earthing of the unit must be
established, the user must be protected against
supply voltage, and the motor must be protected
against overload in accordance with applicable
national and local regulations.
4. The earth leakage current is higher than 3.5 mA.
5. Protection against motor overload is not included
in the factory setting. If this function is required,
set parameter 128 Motor thermal protection to
data value ETR Trip or ETR Warning.
6. Check that the mains supply has been disconnected
before removing the motor and mains plugs.

Warning against unintended start
The motor can be brought to a stop
by means of digital commands, bus
commands, references or local stop,
while the frequency converter is connected to
mains. If personal safety considerations make
it necessary to ensure that no unintended start
occurs, these stops are not sufficient.
While parameters are being programmed, the
motor may start. Consequently, the stop key
[STOP/RESET] must always be activated, following
which data can be modified.
A motor that has been stopped may start if faults
occur in the electronics of the frequency converter, or
if a temporary overload, a fault in the supply mains
or a fault in the motor connection ceases.
