12 Maintenance
Normally, the inverter needs no maintenance or calibration.
Regularly inspect the inverter and the cables for visible damage.
Disconnect the inverter from all power sources before cleaning.
Clean the housing, cover and display with a soft cloth. Ensure the
heatsink at the rear of the inverter cover is not covered.
12.1 Cleaning the contacts of the DC-switch
Clean the contacts of the DC-switch once per year. Perform
cleaning by cycling the switch to ON/OFF positions 5 times. The
DC-switch is located at the lower left of the housing.
12.2 Cleaning the heat sink
An external fan is installed at the bottom of the inverter. When
the fan fails to work normally, the inverter cannot effectively
dissipate heat, and the load drops or the machine may even shut
down. At this time, the fan needs to be cleaned or replaced.
Clean the heat sink with pressurized air or a soft brush. Do not
use aggressive chemicals, cleaning solvents or strong
detergents.
For proper function and long service life, ensure free air

• Wait approx. 30 minutes before cleaning until the heatsink
has cooled down.
