FC 300 Design Guide
Introduction to FC 300
A Cold plate technology
The adjustable frequency drive is built upon a very stable aluminum base integrated with the back
panel. This provides high mechanical stability, efficient cooling and the possibility of cold plate
operation. The cold plate serves as a flat cooling surface on the adjustable frequency drive, where a
majority of t he heat losses dissipates from the electronics to an external cooling surface.
B DC coil
The built-in DC coil ensures low harmonic disturbance of the power supply according to IEC-1000-3-2.
C Air guiding shield
The shield allows cold air to pass by the electronics only. The plastic air guide shield is enclosed in
the package and is easily snapped in place. If the adju stable frequency drive is to operate as a
cold plate drive, the air guiding shield is inserted in the cooling channel through the bottom of the
drive if it is snapped onto the fan. Thus, the amount of heat transferred to t he surroundings via the
cooling air from the fan is reduced.
D Snap-off fan
Like most of th e elements, the fan can eas ily be r e moved for easy cleaning and r emounted .
E Safe Stop
The adjustable frequency drive comes standard with the safe stop functionality for stop category 0
(EN 60204-1) with safety category 3 (EN 954-1) installations. This feature prevents the drive from
starting unintentionally.
F Control signals
Spring-loaded cage clamps contribute to reliability and facilitate easy commissioning and service.
G Options
Options for bus communication, I/O extension etc. can be delivered or ordered built-in from the
factory. Options mounted under the LCP are referred to as option Slot A (top) and option Slot B
(bottom). Option C (see under K Freely programm able option is moun ted on the side of the drive,
while option D is m ounted underneath the control cable decoupling clamps.
H Local Control Panel
The LCP 102 has a graphical user interface. Choos e b etwee n six b uilt-in languages (including Chinese)
or have it customized with your own languages and phrases. Two of the languages can be changed
by the user.
Additionally a simple version, LCP 101, is available with an alpha- n umeric display. A complete
programming of FC 302 can be handled by both LCP’s.
J Hot-pluggable LCP
The LCP can be plugged in or out during operation. Settings are easily transferred via the control panel
from one drive to another or from a PC w ith the MCT-10 set-up s oftware.
" Air Humidity
The adjustable fre quency drive has bee n designed to meet the IEC/EN 60068 -2-3 standard,
EN 50178 pkt. 9.4.2.2 at 122 °
F(50°C).
" Aggressive Environments
An adjustable frequency drive contains a large number of mechanical and electronic components.
All are to some extent vul
nerable to environmental effects.
