Step 3. Remove the Keypad Bracket From the Drive
Refer to figure 5.2 as you perform the procedure.
Step 3.1. If the drive has:
• A Regulator board cover and terminal cover: Remove the three M4
screws from the Regulator board cover. Remove the cover.
• A terminal cover only: If you have this type of drive, this procedure is
easier to perform if you lay the drive on its side. Remove the side cover
from the drive. Use a long magnetized screwdriver to unfasten the four
screws that hold the keypad bracket in place.
Step 3.2. Remove the two M4 screws that fasten the terminal cover (below the keypad).
Step 3.3. Record the wiring to the Regulator board terminal strip.
Step 3.4. Disconnect the wiring from the Regulator board terminal strip.
Step 3.5. Drives with option boards only: Record the wiring connections to the option
board terminals. Disconnect this wiring from the option board terminal strip.
Step 3.6. Pull the keypad assembly partly out of the drive. Spread the retaining clips
on the Regulator board ribbon cable (on the right side) to disconnect it from
the Base Board. See figure 5.3.
Step 3.7. Remove the keypad bracket. Place it with the keypad down on a flat
surface. If you cannot lay it flat, tie it up to prevent damage to wiring.
Step 3.8. Disconnect the green-striped ribbon cable (on the right side of the drive)
from the Regulator board. To disconnect this cable, insert a small
screwdriver inside the cable loop and press in on the retaining clip in the
center of the connector while pulling out the connector. Refer to figure 5.3.
