7.1. CARE

The SM-32 converters must be installed according to the relevant installation regulations.
They do not require any particular maintenance. They should not be cleaned with a wet or
moist cloth. The power supply must be switched off before cleaning.

7.2. SERVICE

The screws of all terminals on the device should be re-tightened two weeks after initial
commissioning. This should be repeated each year.
If inverters have been stored for more than three years, the capacitance of the intermediate
circuit capacitors may have been impaired. Before commissioning these devices, it is
advisable to regenerate the capacitors by connecting them to the voltage for two hours with
the inverter disabled. After these operations the device is ready to be installed without
limitations.
