EPO (Emergency Power Off) RJ45 connector
To activate EPO pin 4 and pin 5 must be shorted.
Make sure the RJ45 plug is properly
attached to the wire.
Ensure that the EPO function operates
properly with your application by testing the
inverter while it is injecting current. Check
that the inverter stops injecting current.
