7. Maintenance

7.1. Care

The SM32 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.

7.3. Repairs

Repairs of the device should only be carried out by the specialist personnel (quali-
fied by the manufacturer).

7.4. Customer Service

For customer service, please contact your Gefran office.
