Remove Components
1.
Read and follow the
Safety Precautions on page 8
and
Important Initial
Steps on page 10
.
2.
Cut the wire ties for the
wiring harness along the Gate
Interface Boards.
3.
Note wire routing and
location of sensors.
4.
For the Main Control Panel
thermal sensor, remove its
screw and nut on the Main
Control Panel and
disconnect the other end
from the wiring harness.
Note:
This screw and nut are
small. Take care to not drop
or misplace.
5.
For the Heatsink thermal sensor, remove its screw on the Heatsink above
the SCR modules and unplug the other end from the wiring harness.
Note:
This screw and nut are small. Take care to not drop or misplace.
6.
Unplug the J8 connectors on each of the three Gate Interface Boards. See
page
for connector locations.
7.
Unplug the other end of this wiring harness at the J6 connector on the
Power Interface Board. See page
for connector locations.
Install Components
1.
For the Main Control Panel thermal sensor or the Heatsink thermal sensor,
apply a thin layer of supplied thermal grease to the metal side of the new
Thermal Sensor and install it with supplied screw with star washer toward
the panel. Torque screw to 1.7 N•m
(15
lb•in).
2.
For the three Gate Interface Boards, carefully route wires and connect to J8
on each Gate Interface Board. Be sure that the J8 connectors go to the
correct IGBT. See page
for connector locations.
3.
Reconnect the other end of this wiring harness at the J6 connector on the
Power Interface Board. See page
for connector locations.
4.
Reassemble remaining components in reverse order.
5.
Replace all safety shields and enclosure covers before applying power to the
drive.
