7. Maintenance

CanadianSolar
The Canadian Solar U.S. Three Phase series inverters do not require any regular maintenance.
However, cleaning the dust off the heat sink will help dissipate heat away from the inverter,
which will increase the life of the inverter.
CAUTION
Do not touch the surface when the inverter is operating. Some parts may
be hot and cause burns. Turn OFF your inverter (refer to Section 6.2) and
let it cool down before any maintenance or cleaning is performed on the
inverter.
The LCD and LED status indicator lights can be cleaned with a soft cloth if they are too dirty to
read.
NOTES
Never use any solvents, abrasives or corrosive materials to clean the
inverter.
