Main HVIL Loop
IMD Setup
VCU Outputs Setup
In most cases, there are options for output control. In cases where an AEM PDU-8 control output is available, we
recommend using the PDU-8 over other methods. The current limiting and fault detection features increase safety and
reliability. This is especially important for high voltage contactor control.

The high voltage system in an electric vehicle is designed
to be ungrounded (floating) with respect to the vehicle
chassis (frame). Insulation faults can cause electric shock,
personal injury and even death. An insulation monitoring
device (IMD) must be used to protect against these faults.
