1.5.2 Installing the Current Sensor Wire
Harness
Install the new current sensor wire harness using the following
procedure. Refer to Illustration 1.8.
1.
Connect the following items to the power card:
1a
Plug the 16-pin cable into MK102.
1b
Attach the heat sink cable to 3-pin
connector.
1c
Secure the screw (M5) attaching the ring
terminal ground.
2.
Connect the other end of the heat sink cable.
3.
Attach the cable to the 3-pin connector on the high-
frequency card.
4.
Plug a cable into each of the 3 current sensors.
5.
Secure the wire harness with the cable ties.
1.5.3 Installing the Upper Capacitor Bank
Reinstall the upper capacitor bank assembly using the
following procedure. Refer to Illustration 1.5.
The upper capacitor bank weighs approximately 9 kg (20 lb).
1.
Place the upper capacitor bank assembly in its
original position in the unit.
2.
The capacitor bank connection to the DC busbars is
recessed in the gap between the upper and lower
capacitor banks. A minimum extension of 150 mm (6
in) is required. Secure the 6 connection nuts (M5) to
the capacitor bank.
3.
Secure 4 retaining nuts (M6), 1 in each corner of the
upper capacitor bank assembly.
4.
Connect the IGBT wire harness to the following
connectors on the gatedrive card.
4a
MK100 (NTC)
4b
MK101 (if RFI filter option is present)
4c
MK102 (U)
4d
MK103 (V)
4e
MK104 (W)
4f
MK105 (if brake option is present)
4g
MK106

1.5.4 Installing the IGBT Output Busbars
Reinstall the IGBT output busbars using the following
procedure. Refer to Illustration 1.4
1.5.5 Installing the Input Terminal Mounting
Reinstall the input terminal plate and busbars using the
following steps. See Illustration 1.2 and Illustration 1.3. Optional
components mounted on the input terminal plate can result in
differing configurations. These options include:
The terminal plate and options weigh up to 20 kg (44 lb).

1.
Place 3 busbars in position over the fan housing.
2.
Secure 3 retaining nuts (M10), 1 at the upper end of
each of the 3 IGBT output busbars.
3.
Secure 3 retaining screws (M10), 1 at the lower end
of each of the 3 IGBT output busbars.
Plate
•
Input disconnect.
•
RFI filter.
•
AC fuses with cooling fan.
1.
Place the input terminal plate in its original position.
2.
Secure the input terminal plate with 8 retaining nuts
(M6).
3.
If a disconnect option is present, reattach to the
terminal plate assembly as follows:
3a
Slide on the disconnect to clear the fuses
and place it in position.
3b
Secure the 4 mounting screws (T40).
3c
Tighten the connection nut (17 mm)
between each fuse and the disconnect.
4.
If an RFI filter option is present, reconnect the cable.
5.
If a fuse option with cooling fan is present, connect
the cooling fan cable.
6.
Secure the uppermost retaining nut (M10) on each of
the 3 input busbars.
7.
Connect input power wiring to terminals R (L1), S
(L2), T (L3), and ground.
