It Mains - Danfoss FC 300 Operating Instructions Manual

FC 300 Operating Instructions
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 mm2 or 2 rated earth wires terminated separately.
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.

IT Mains

Do not connect 400 V frequency converters with RFI-filters to mains supplies with a
voltage between phase and earth of more than 440 V.
For IT mains and delta earth (grounded leg), mains voltage may ex-
ceed 440 V between phase and earth.
Par. 14-50 RFI 1 can on FC 302 be used to disconnect the internal RFI capacitiors from the RFI
filter to ground. If this is done it will reduce the RFI performance to A2 level.
