Assembly 1. Place the new assembly into the drive (with the snubbers to the right),
and rest the lower bracket (or busbar) on the mounting peg.

bottom of the assembly. Torque the Glastic™ surface to
25 lb-ft and the busbar mounting surface to 25 lb-ft.

former board. Ensure that the connectors for all six assemblies in the
drive are secure.
Note: Match the board names (i.e. A14R) with the wire labels (i.e.
A14R-J1) to verify proper connections.

(upper assemblies only). Ensure that the connectors for the three upper
assemblies are secure.
