What to do if fault indicator is on Magnum CSW412 Inverter?
If the fault indicator is on and there is no AC output from your Magnum Inverter, you need to determine and resolve the fault condition. This could be due to high or low voltage, an excessive load, or over-temperature. Also, check the error code on the display and use Table 4-2 to correct.
What to do if Magnum CSW412 Inverter has no AC output but status indicator is green?
If there is no AC output from your Magnum Inverter and the status indicator is green, check the connected load and reset the GFCI.
How to fix a Magnum CSW412 Inverter with no AC output and the status indicator is off?
If your Magnum Inverter has no AC output and the status indicator is off, first, ensure the unit is turned on. See Operation instructions. Then, check if the fuse or disconnect switch (if installed) is either blown or turned off.
What to do if my Magnum CSW412 Inverter shows E03 error?
If your Magnum Inverter displays error code E03, it means the unit's output has detected an overload or short circuit, causing it to shut down. To resolve this, inspect the load connected to the inverter's output, decrease the load, and then restart the unit.
Why does my Magnum CSW412 Inverter show E04 error and how to fix it?
If your Magnum Inverter displays error code E04, it indicates that the unit has sensed a high internal temperature and shut down. To fix this, turn the inverter off, wait 15 minutes before turning it back on, and check to ensure that the airflow around the unit is not obstructed.
What does E01 mean on my Magnum CSW412 and how do I fix it?
If your Magnum Inverter displays error code E01, this means the input voltage is low (below 10.5 VDC) and the unit will shut down soon. You should immediately recharge the battery to at least 11.8 VDC, and then restart the unit.
What does E02 error code mean on Magnum CSW412 Inverter?
If your Magnum Inverter displays error code E02, it signifies that the unit has detected a high input voltage and has shut down. You should check the battery voltage or inspect any external charger connected to the battery bank.
What does E05 mean on a Magnum CSW412 Inverter?
If your Magnum Inverter displays error code E05, it means the unit has sensed a low input voltage and initiated a warning alarm (at 11.2 VDC). Recharge the battery to at least 11.8 VDC, as the unit will shut down shortly.
What does E07 error mean on Magnum CSW412?
If your Magnum Inverter displays error code E07, it indicates that the unit has sensed a high internal temperature and is nearing the thermal shutdown limit. To resolve this, reduce the load and check for any blockages in the unit’s ventilation.
What does E06 mean on Magnum CSW412?
If your Magnum Inverter displays error code E06, it means that the connected load is close to the overload shutdown limit. Reduce the connected load to resolve this issue.
