6.4 INFORMATION FOR CONTACTING TECHNICAL SUPPORT
NOTE!
For technical support and servicing, it is important to have the following information in hand:
Inverter model;
Serial number, manufacturing date, and hardware revision that are listed in the product nameplate
(refer to item 2.4);
Installed software version (check parameter P0023);
Application data and inverter settings.
6.5 PREVENTIVE MAINTENANCE
DANGER!
Always turn off the mains power supply before touching any electrical component associated to
the inverter.
High voltage may still be present even after disconnecting the power supply.
To prevent electric shock, wait at least 10 minutes after turning off the input power for the complete
discharge of the power capacitors.
Always connect the equipment frame to the protective ground (PE). Use the adequate connection
terminal in the inverter.
ATTENTION!
The electronic boards have electrostatic discharge sensitive components.
Do not touch the components or connectors directly. If needed, first touch the grounded mettalic
frame or wear a ground strap.
