The door of the DC link is classified as a low voltage door. An interlock
prevents the door opening unless fan power is disconnected. The fan power
disconnect handle is on the right hand side of the door.
The LV components are mounted on fixed panels and are behind the DC link
door. The medium voltage area is behind the low voltage panel of the DC link
cabinet. The DC link is mounted on the floor plate.
Power connectors of the DC link inductor are identified as L+. L-, M+, and M-.
A current sensor is on the M+ conductor. The DC links have integral thermal
protection.
