This error may appear in version 1.9.2 or higher. It indicates that the N and L wires are reversed, which could damage and potentially burn the motherboard.
To prevent this error and the subsequent damage, please follow Etrel INCH electrical and physical installation guides and the phase markings on the protection element, located inside the INCH charger.
3 phase connection
CORRECT
WRONG
L1 and N are reversed
L2 and N are reversed
L3 and N are reversed
Please measure the voltage between each phase and ground.
