Converting the HCW 3 to HCW 5

Remove electrical power supplied to the cabinet.

Remove both end panels.

Remove four nuts holding top cap.

Remove top cap.

Set HCW 2 in place by using same stud holes which the top cap used.

Install four nuts which held top cap to retain HCW 2.

If your HCW 3 is a three phase unit, then connect the four wires from the HCW 2 as follows:

1. Connect one wire coming from the HCW 2 infinite regulator to an empty terminal on the L3 quick-connect terminal block.

2. Connect the other wire coming from the HCW 2 infinite regulator to an empty terminal on the L2 quick-connect terminal block.

3. Connect the wire which comes from the fuse in the HCW 2 to the L2 screw-clamp terminal block. This should make a total of three wires in this block.

4. By using a two-blade quick-connect adapter, connect the remaining wire to the neutral (N) quick-connect terminal block.

5. Be sure to study enclosed marked field wiring diagram accompanying the HCW 2.

If your HCW 3 is a single phase unit, then connect the four wires from the HCW 2 as follows:

1. By using a two-blade quick-connect adapter, connect one wire from the HCW 2 infinite regulator to the L1 quick-connect terminal block.

2. Connect the other wire coming from the HCW 2 infinite regulator to the empty terminal on the L2 quick-connect terminal block.

3. Connect the wire coming from the fuse in the HCW 2 to the L2 screw-clamp terminal block. This should make a total of 3 wires in this block.

4. By using a two-blade quick-connect adaptor, connect the remaining wire to the neutral (N) quick-connect terminal block.

5. Be sure to study enclosed marked field wiring diagram accompanying the HCW 2.

Your wiring now should match that of a standard HCW 5.

Test out all systems.

Replace the end panels.
