1. With the drive energized, check that all output voltages are present (view
1).
2. De-energize the drive, isolate and lock out the control power, and remove
all wire connections from the unit (view 1).
3. Remove four (4) M6 (H.H.T.R.S.) so you can remove the DC/DC power
supply assembly from the low voltage panel (view 1).
4. Remove four (4) M4 (P.H.M.S.) and nylon shoulder washers from the
back of the mounting plate (view 2)
