3.2 Installing the IGBT Output Busbars
To install the new IGBT output busbars, use the following steps.
Procedure
Install the 2 new IGBT output busbars:
Position the 3 new IGBT output busbars in the drive.
The new IGBT output busbars have PEM studs at the bottom rather than holes for fasteners.
Fasten 6 screws (T30), 2 at the top of each IGBT output busbar.
Fasten 3 thread-forming screws (T25), 1 at the top of each IGBT output busbar.
Install the new hex busbar support bracket:
Position the bracket over the 3 IGBT output busbars.
Fasten 3 M5 nuts (8 mm) to secure the bracket.
Install the gate drive card:
Fasten 6 thread-forming screws (T20) in the edges of the card.
Reconnect all cables to the gate drive card connectors.
Install the DC bus rails:
Fasten 2 screws (T30) in the top end of the DC bus rails, 1 per bus rail.
Fasten 2 nuts (10 mm) in the lower end of the DC bus rails, 1 per bus rail.
Install the power card mounting plate:
Secure 4 screws (T20) in the corners of the mounting plate.
Fasten 1 screw (T25) at the top center of the mounting plate.
Reconnect all cables to the power card, and route the cables through the cable clips on the mounting plate.
Install the control card mounting plate.
Reconnect the ribbon cable connecting the control card and power card, and position the control card mounting
plate in the drive.
Secure 4 screws (T20) in the corners of the control card mounting plate.
Reconnect the customer control wiring.
