Cleaning the Fans and Cooling Plenum
The XGI 1500V inverter has three fans on the right-hand side of the enclosure. These fans are protected with
finger guards. Over time, these guards may collect debris that restricts airflow and reduces the effectiveness of
the cooling system. Keeping the fans and cooling plenum clean will prevent the inverter from overheating.
To clean the fans:
1. Turn off the inverter, first by moving the DC Switch on the inverter to the “OFF” position, then by turning
the AC Switch on the inverter to the “OFF” position.
2. Use a vacuum with a non-metallic nozzle to remove the debris from the fan guards. Use a stiff nylon
brush to loosen any stubborn debris.
