Internal Wiring for the Dual Configuration of the
Braking Units
The dual-configuration braking units may be applied to any type of inverter modules mentioned in section 1.
The connections required for the parallel connection of two braking units by means of one splitter boards are
as follows:
N. 2 power connections with copper bar 60*10mm for DC supply.
N. 3 connections with unipolar, twisted pair cables AWG 17-18 (1mm
2
) for the connection of the low-voltage
DC supply to the electronic boards.
Connections required:
-
from splitter board in inverter leg W to splitter board in braking unit BU1 (power 24-BU splitter
board)
-
from driver board in inverter leg W to driver board in braking unit BU1 (power supply +24-BU1 driver
board)
-
from driver board in braking unit BU1 to driver board in braking unit BU2 (power 24-BU2 driver
board).
N. 6 optical fibre connections, 1mm, standard single plastic material (typical damping: 0.22dB/m), with
connectors type Agilent HFBR-4503/4513.
Connections required:
-
from splitter board in braking unit BU1 to control unit (fault signal BU)
-
from control unit to splitter board in braking unit BU1 (gate signal BU)
-
from driver board in braking unit BU2 to splitter board in braking unit BU1 (fault signal BU2)
-
from splitter board in braking unit BU1 to driver board in braking unit BU2 (gate signal BU2)
-
from driver board in braking unit BU1 to splitter board in braking unit BU1 (fault signal BU1)
-
from splitter board in braking unit BU1 to driver board in braking unit BU1 (gate signal BU1)
