Frequency converter Fc102 (quick guide)
saFety instructions
• Check that the frequency converter is correctly connected
to earth.
• Do not pull out the mains or motor contacts or other power
connections when the frequency converter is connected to
the power supply grid.
• Protect the user from mains voltage.
• Protect the motor against overload in accordance with
national and local regulations.
• The leakage currents to earth exceed 3.5 mA, see Design guide.
• The [Off] button is not an isolator switch. It does not discon-
nect the frequency converter from the mains.
Warning!
Warning high voltage
The frequency converter is subject to highly
dangerous voltages when it is connected to
the mains. Incorrect installation of the motor
or frequency converter can lead to material
damage, serious personal injury or death.
Follow the instructions in this manual as well
as local and national provisions and safety
regulations.
Warning!
discharge time!
Frequency converters have DC bus capacitors
that can hold a charge even after the mains vol-
tage has been disconnected. Prevent electrical
hazards by disconnecting the mains voltage,
disconnecting permanent magnet motors and
DC bus supplies, including battery backup, UPS
and DC bus connections for other frequency
converters. Wait until the capacitors have fully
discharged before carrying out maintenance or
repairs. Read more about the discharge waiting
times in the table below. Starting to service or
repair the unit immediately after cutting the
power supply, without waiting for the specified
period, can lead to death or serious personal
injury.
take care!
residual current device:
This product can cause a direct current in
the protective earth conductor. When using a
residual current device as additional protec-
tion, use only a type B residual current device
(delayed) on the input side of this product. See
also Danfoss application note for the MN90G
RCD.
The protective earthing of the frequency
converter and the use of RCDs must always
follow national and local regulations.
take care!
it system (3x230vac)
When installing the FC102 on an isolated
system (IT system, 3x230VAC) set parameter
14-50 to [0] Off.
Press [Main Menu] twice. Navigate using
the [
