Common wiring errors
1、Power input/output confusion: incorrect connection of power input line to circuit breaker output terminal
Confusion of single-phase/three-phase wiring:
2、Single phase system: Incorrect connection of live wire (L) to neutral wire (N) terminal.
Three phase system: phase sequence connection error (L1/L2/L3 confusion), or missing neutral wire (N) and ground wire (PE).
Communication error:
1、4G antenna not connected or loose: resulting in weak or no signal.
2、Improper installation of SIM card: not inserted properly, facing in the wrong direction, or not activated.
Loose wiring or inconsistent wire diameter: The wire is not tightened or the cross-sectional area is too small, resulting in heating and poor contact.
