Step 17: Reinstall the Power Wiring.
! Important: Be careful that no loose strands are created when inserting
the wires into the terminal block.
 Reconnect ac input leads at terminals U1, V1 and W1.
 Reconnect motor leads at terminals U2, V2 and W2.
 Reconnect the green/yellow ground lead at terminal PE.
! Important! Because of the difference in ground terminal design, the
green/yellow wire may have been stripped deeper than is necessary for the ACH550. It may be
necessary to trim the end of the conductor for proper insertion into the new terminal.
Step 18: Reinstall the new control cable.
! Important: Be careful that no loose strands are created when inserting
the wires into the terminal block.
 Locate the new control cable supplied with the new drive. This cable
is a multi-conductor cable with a black sheath. The end for the bypass
unit is labeled “2PCB.X2” and has the shorter wires extending.
 Reconnect the color coded wires on both ends according to the table
below.
