Silent Knight 5820XL·1 view·0 field notes

What This Code Means

An earth ground fault occurs when the panel senses an unexpected flow of current from one or more of its terminals to the earth connection (Terminal 2).

Common Causes

1Unexpected flow of current from one or more terminals to the earth connection (Terminal 2)
2A computer connected to the panel via a serial cable attached to the panel’s 9-pin connector

Resolution Steps

Isolate the wiring that is causing the fault by removing wiring connections one at a time until the earth fault is no longer present. Pause at least five seconds after removing a wire before removing the next one. If a computer is connected to the panel via a serial cable, the trouble will clear automatically when you disconnect the computer from the cable.
