Installation Guidelines 3-3
3.3.2 Making an Input Entry Hole
If your Power Module has an extra input bay installed, proceed as follows. If your
Power Module will have a top-hat enclosure over the disconnect bay, mount the
top-hat enclosure before continuing.
To make an input entry hole, select the ideal hole placement (within the constraints
shown in figure 3.1), then perform the steps that follow.
Step 1. Remove the lifting angle, if it is still attached.
Step 2. Remove the top plate from the disconnect bay (or from the top-hat
enclosure).
Step 3. Punch hole(s) for the AC input entry within the area shown in figure 3.1.
Step 4. Replace the top plate on the drive.
Step 5. Replace the lifting angle.
3.3.3 Connecting the AC Input Wires to the Busbars
Use the following procedure to connect the input wires to the input busbars in the
disconnect bay. Refer to Appendix A for busbar specifications.
Step 1. Thread the input wires through the entry hole on the top of your drive.
Step 2. Fasten the input wires for each phase onto the appropriate phase busbar
(see the busbar illustrations shown in Appendix A).
Step 3. Torque all bolts to 45 lb-ft.
