Insulation Monitoring Device (IMD)
Overview
The Insulation Monitoring Device (IMD) is used to protect the system against high voltage
leaks. If a high voltage leak is detected by the IMD, the HV system will be interrupted.
The IMD is fastened to the same bracket as the RFU, which is located on the right side of the
wheel box and motor controller. The bracket consists of two halves, one side is removable,
and the other side is bonded to the wheel box.
