4.3 Identifying Component Faults

4.3.1 Identifying AC SPD Faults

Check the color of the AC SPD indication window. Green indicates that the AC SPD is
normal. Red indicates the AC SPD is faulty.

4.3.2 Identifying Circuit Breaker Faults

The following indicate that the circuit breaker is faulty:

Issue 02 (2019-02-26)
Check whether the AC SPD indication window is red. If so, replace the SPD.
Check whether the AC SPD detection cable is disconnected. If so, reconnect the cable.
The DC SPD detection cable is disconnected.
The DC SPD is faulty.
Check whether the DC SPD detection cable is disconnected. If so, reconnect the cable.
If the DC SPD detection cable is reliably connected, replace the DC SPD.
The circuit breaker cannot be switched to ON/OFF after the short circuit fault for its end
circuit is rectified.
When the circuit breaker is switched to ON and its input voltage is normal, the voltage
between the two ends of the circuit breaker exceeds 1 V.
The input voltage is normal, but the resistance between both ends of the circuit breaker is
less than 1 kΩ when the circuit breaker is OFF.
The AC input and slot connector are normal, but the Fault indicator (red) is steady on or
all indicators are off.
The slot connector and SMU are normal, but the Alarm indicator (yellow) still blinks
after the rectifier is reinstalled.
The AC input and SMU are normal, but the SMU cannot control the rectifier.
The DC output is normal but the green indicator on the SMU is off.
