FC 300 Operating Instructions
These Operating Instructions can be used for all FC 300 frequency converters with software
version 4.0x.
The software version number can be seen from parameter 15-43.

High Voltage Warning

"
The voltage of the FC 300 is dangerous whenever the converter is connected to mains.
Incorrect fitting of the motor or frequency converter may cause damage to the equipment,
serious injury or death. Consequently, it is essential to comply with the instructions in
this manual as well as local and national rules and safety regulations.

Safety Instructions

"
Make sure the FC 300 is properly connected to earth.
•
Do not remove mains plugs or motor plugs while the FC 300 is connected to mains.
•
Protect users against supply voltage.
•
• Protect the motor against overloading according to national and local regulations.
Motor overload protection is not included in the default settings. To add this function, set parameter
•
1-90 Motor thermal protection to value ETR trip or ETR warning. For the North American market:
ETR functions provide class 20 motor overload protection, in accordance with NEC.
• The earth leakage current exceeds 3.5 mA.
The [OFF] key is not a safety switch. It does not disconnect the FC 300 from mains.
•
General warning
Warning:
Touching the electrical parts may be fatal - even after the equipment has
been disconnected from mains.
Also make sure that other voltage inputs have been disconnected, such as load-sharing (linkage
of DC intermediate circuit), as well as the motor connection for kinetic back-up.
Using VLT AutomationDrive FC 300: wait at least 15 minutes.
Shorter time is allowed only if indicated on the nameplate for the specific unit.
Leakage Current
The earth leakage current from the FC 300 exceeds 3.5 mA. To ensure that the earth cable has
a good mechanical connection to the earth connection (terminal 95), the cable cross section
must be at least 10 mm
Residual Current Device
This product can cause a D.C. current in the protective conductor. Where a residual current device
(RCD) is used for extra protection, only an RCD of Type B (time delayed) shall be used on the
supply side of this product. See also RCD Application Note MN.90.GX.02.
Protective earthing of the FC 300 and the use of RCD's must always follow national and local regulations.
