the motor, frequency converter or fieldbus may cause
death, serious personal injury or damage to the
equipment. Consequently, the instructions in this

MG18B302 - Rev. 2013-09-02
Disconnect mains supply to the frequency
converter whenever repair work is to be carried
out. Check that the mains supply has been
disconnected and that the necessary time has
elapsed before removing motor and mains supply
plugs.
The [Off] key does not disconnect the mains
supply and consequently it must not be used as a
safety switch.
The equipment must be properly earthed, the
user must be protected against supply voltage
and the motor must be protected against
overload in accordance with applicable national
and local regulations.
The earth leakage current exceeds 3.5 mA.
Protection against motor overload is not included
in the factory setting. If this function is desired,
set 1-90 Motor Thermal Protection to data value [4]
ETR trip 1 or data value [3] ETR warning 1.
Do not remove the plugs for the motor and
mains supply while the frequency converter is
connected to mains. Check that the mains supply
has been disconnected and that the necessary
time has elapsed before removing motor and
mains plugs.
Note that the frequency converter has more
voltage sources than L1, L2 and L3, when load
sharing (linking of DC intermediate circuit) or
external 24 V DC are installed. Check that all
voltage sources have been disconnected and that
the necessary time has elapsed before
commencing repair work.
The motor can be brought to a stop with digital
commands, bus commands, references or a local
stop, while the frequency converter is connected
