This document refers to a known issue with EPO circuts in DCX units.
The EPO (Emergency Power Off) circuit can be enabled and trip the main DCX breaker even if the EPO switch is disabled. This will occur if the EPO NO (Normally Open) connection comes in contact with GND (Ground) or Facility RTN (Return). For example if the wire touches conduit, the batter stack frame, a ground bar, Battery return etc.
