Inrush Current Limit Circuit Overheat

What does E.IOH mean?

The inverter output is shut off when the resistor in the inrush current limit circuit has overheated, indicating a fault within this circuit. This typically results from frequent power ON/OFF cycles or a damaged component within the inrush current path. Continued operation with this fault risks further component damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Inspect the power supply circuit and contactor of the inrush current limit for any physical damage.

2. 4

   If the problem persists after these steps, contact your sales representative.
