2.3 Removing the Mains Terminal Block

To remove the mains terminal block, use the following steps.

Procedure

Disconnect the customer input power wiring.
Remove the R/S/T terminal label.
Remove 2 screws (T25) at the bottom of the mains terminal block.

If necessary, also remove 1 screw (T25) from the EMC shield near the lower end of the terminal block.

Slide the mains terminal block down to release it from the 2 metal clips on the mounting plate.

Discard the mains terminal block and terminal label.

2.4 Removing the Brake/Regen Terminal Block

If the drive includes either the brake option or regen/load share option, remove the terminal block using the following steps.

Procedure

Disconnect the wiring for the brake option or regen/load share option.

The brake/regen terminals are labeled R(+) and R(-).

Remove the R(+) busbar:

Unfasten 1 M4x8 thread-forming screw (T20) from the busbar at the terminal block.
Unfasten 1 screw (T40) at the upper end of the busbar.

Remove the R(-) busbar:

Unfasten 1 M4x8 thread-forming screw (T20) from the busbar at the terminal block.
Unfasten 1 M8 nut (13 mm) at the upper end of the busbar.

Remove 2 screws (T40) from the brake/regen terminal block.
Remove the brake/regen terminal block from the drive.

2.5 Removing the Motor Terminal Block

Procedure

Disconnect wiring to the motor.
Remove the U/V/W terminal label.
Remove the EMC shield:

Unfasten 2 screws (T25) from the base of the EMC shield.
Release the current sensor wiring from the cable clips on the EMC shield.

Remove the U motor busbar:

Remove 1 thread-forming screw (T25) from the middle of the busbar.
Unfasten 1 screw (T30) at the current sensor end of the busbar.

Remove the V motor busbar:

Remove 1 thread-forming screw (T25) from the middle of the busbar.
Unfasten 1 screw (T30) at the current sensor end of the busbar.

The V screw is shorter than the U and W screws.

Remove the W motor busbar:
