See figure 3.12 (15 to 25 HP @ 460 VAC) or 3.13 (25 to 60 HP @ 460 VAC) for part
locations.
Step 3.1 Record connections to the Regulator board terminal strip if they must be
disconnected to remove the keypad bracket.
Step 3.2 Loosen the thumb screw on the left side of the keypad bracket. Hold the
bracket on the left and lift the bracket up and to the left to separate it from
the keypad support bracket.
Important: The keypad support bracket is connected to the drive by wiring. Do not lift
the bracket out completely, because this can damage or pull out wiring.
Tie up or support the bracket to prevent damage to the wiring.
Step 3.3 Disconnect the 26-conductor Regulator board ribbon cable from the Power
Supply board (located on the right side below the keypad). You can see the
connector through the slot on the keypad support bracket. Use a small
screwdriver inserted through the slot to spread the retaining clips on the
connector to release it.
