Step 2.
Verify that the DC Bus Capacitors are Discharged
Step 2.1 Use a voltmeter to verify that there is no voltage at the drive’s AC input
power terminals (R/L1, S/L2, T/L3).
Step 2.2 Ensure that the DC bus capacitors are discharged. To check
a. Stand on a non-conductive surface and wear insulated gloves.
b. Use a voltmeter to measure the DC bus potential at the DC bus power
terminals shown in figure 2.3.
Step 3.
Remove the Keypad Bracket from the Drive
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 bracket is connected to the drive by wiring. Do not attempt to lift the
bracket out completely as this can damage or pull out wiring. Tie up or
support the bracket to prevent damage to the wiring.
Step 3.3 Spread the retaining clips on the 26-conductor Regulator board ribbon
