driver board in inverter leg U1, from this driver board to the next in inverter leg V1, from this driver board to
the next in inverter leg W1) (+24V supply to IGBT driver boards)
-
from driver board in inverter leg W1 to optional braking unit BU[*] (+24V supply to braking unit)
-
from power supply unit 2 to the driver boards for each inverter leg 2 (from the power supply unit to driver
board in inverter leg U2, from this driver board to the next in inverter leg V2, from this driver board to the
next in inverter leg W2) (+24V supply to IGBT driver boards)
-
from power supply unit 1 to the splitter boards (+24V supply to splitter boards) (from the power supply unit
to the splitter board in inverter leg U1, from this splitter board to the next in inverter leg V1, from this splitter
board to the next in inverter leg W1
-
from splitter board in inverter module W1 to control unit (+24V supply to control unit)
N. 13 optical fibre connections, 1mm, standard single plastic material (typical damping: 0.22dB/m), with
connectors type Agilent HFBR-4503/4513 (N. 15 connections if an optional braking unit is installed).
