Order form
This section makes it easier for you to specify and
order an FCD 300.
Choice of frequency converter
The frequency converter must be chosen on the ba-
sis of the present motor current at maximum loading
of the unit. The frequency converter’s rated output
current I
INV.
must be equal to or greater than the re-
quired motor current.
Mains voltage
FCD 300 is available for mains voltage range: 380-
480 V.
The frequency converter is connected to a mains
voltage of:
-
3 x 380 - 480 V three-phase AC voltage
3 x 380 - 480 Volt mains voltage

Enclosure
All FCD 300 units are supplied with IP 66, NEMA 4x
(Indoor) enclosure as standard.
■
Brake
FCD 300 is available with or without an integral
brake module. See also the section entitled
Brake
resistors
for ordering a brake resistor.
Including mechanical brake control/supply.
■
24 V external supply
Back up of control supply with 24 V DC is available
as optional function.
■
RFI filter
FCD 300 has an integral 1A RFI-filter. The integral
1A RFI filter complies with EMC standards EN
55011-1A. See the sections
Cable lengths
and
Cross section
for further details.
■
Harmonic filter
The harmonic currents do not affect power con-
sumption directly, but they increase the heat losses
in the installation (transformer, cables). That is why
in a system with a relatively high percentage of recti-
fier load it is important to keep the harmonic currents
at a low level so as to avoid a transformer overload
and high cable temperature. For the purpose of en-
suring low harmonic currents, the units are fitted with
coils in their intermediate circuit as standard. This
reduces the input current I
RMS
by typically 40 %.
■
Display unit
On the FCD 300 unit there are 5 indicator lamps for
voltage (ON), warning, alarm, status and bus.
In addition, an LCP control panel to be connected
via a plug to the frequency converter is available as
an option. The LCP control panel can be installed
up to 3 metres away from the frequency converter,
e.g. on a front panel, by means of a mounting kit.
All displays of data are via a 4-line alpha-numerical
display, which in normal operation is able to show 4
operating data items and 3 operation modes continu-
