Moving the AC Supply Terminals
The AC supply terminals - L1, L2 & L3 - can be made available at the top or bottom of the drive. The factory-
delivered drive has the AC terminals in the lower position.
It only takes a few minutes to rotate the AC terminals to the upper position.
1. Remove the fixings that secure the Phase Assembly front cover.
2. Remove the two screws on the front of the phase assembly moulding that secure the handle in place. The
handle is located at the top of the phase assembly. It looks like another AC terminal but it is electrically
isolated. It is there to assist in handling the phase assembly and is used when securing the stabilising
bracket. Refer to "

3. Withdraw the handle from the phase assembly.
4. Slowly remove the central bolt and washer from the AC busbar and catch the ACCT and large
rubber washer that are secured by the bolt. Remove the ACCT and large rubber washer.
5. Withdraw the AC busbar from the phase assembly.
6. Flip the AC busbar over (see opposite) and slide the AC busbar into position through the end of the
Phase Assembly (upper position) and secure the ACCT and large rubber washer with the central
bolt and washer. Torque to 42Nm (31 ft.lbf).
7. Fit the handle to the lower position and secure using the two screws. Hand-tighten.
