Break-outs
After removing the break-out, ensure that the ground tab is connected to ground (see
Figure 4-11). This will connect 0V of the drive to ground. This is required to enable the
drive to meet IP20 when the break-out is removed.
WARNING
Do not remove break-out if the connections are not required.
