5　Maintenance

Regular maintenance can ensure that the inverter maintains great performance.

DELTA recommends that the unit should be inspected at least every 6 months. The

maintenance frequency should be adjustable, depending on the sit environment,

different seasons and weather effects.

LED indicators are off to avoid the risk of electric shock!
