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 Use a magnetic screwdriver to remove the M4 x 10 screws that fasten the
bottom of the keypad support bracket to the drive.
Step 3.3 Spread the retaining clips on the Regulator board ribbon cable (on the right
side) to disconnect it from the Base Board.
Step 3.4 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 4. Install the RMI Board in the Keypad Bracket
Refer to figure 3.6 for component locations.
Step 4.1 Remove the RMI board from its anti-static wrapper and verify that the
jumper settings are correct. Refer to figure 2.1 for jumper locations and
appendix A for jumper settings.
Step 4.2 Align the key on the Regulator board’s 34-conductor ribbon cable connector
with the slot in the RMI board’s connector. Press the ribbon cable connector
in until it locks into position.
Step 4.3 Route the other ribbon cable out of the side of the keypad bracket.
Step 4.4 Align the RMI board on the four mounting tabs on the keypad bracket. Make
sure that the ribbon cable is not pinched between the keypad bracket and
the RMI board.
Step 4.5 Fasten the RMI board to the right side of the keypad bracket using the two
metal M3 screws and lock washers for proper grounding. Fasten the left
side using the two 6-32 screws and lock washers for proper grounding.
Important: You must use the lock washers to properly ground the RMI board.
Improper grounding of the RMI board can result in erratic operation of the
drive.
Step 5. Reinstall the Keypad Bracket in the Drive
Step 5.1 Place the keypad support bracket back into position. Use a magnetic
screwdriver to fasten it to the drive with the screws removed in step 3.2.
Step 5.2 Realign the 26-conductor ribbon cable connector with the connector inside
the slot in the keypad support bracket. Carefully press the ribbon cable
connector in until the retaining clips lock into place.
Step 5.3 Connect the RMI wiring to the appropriate RMI terminals for your
application. Route the wire through the left-most wire-routing hole at the
bottom of the drive. Refer to section 3.9 for terminal identification.
Step 5.4 Reconnect any wiring that was removed from the Regulator board terminal
strip. Refer to the terminal connections documented in step 3.1 or to the
appropriate instruction manuals for the devices being used.
Step 5.5 NEMA 4X/12 drives only: Before installing the cover, check that the gaskets
on the cover are flat and within the gasket channels.
