Figure 68 - DC Link/Fan cabinet with panel removed to show CMC (heatpipe model)

The door of the cabinet interlocks to remain closed until you disconnect the fan
power. The fan power disconnect handle is on the right-hand side of the cabinet.
The DC link and fan are behind the fixed fan control panels in the medium
voltage compartment.

The DC link is on the floor plate of the cabinet. Airflow barriers assembled
around the coils of the inductor direct a portion of the cooling air through the
inductor.

Power connects to the inductor via flexible leads. There are four power
connection points labeled L+, L-, M+, and M-. There is a current sensor on the
M+ conductor.
