6.4 INFORMATION NECESSARY FOR CONTACTING TECHNICAL SUPPORT

NOTE!
For technical support or queries, it is important to have the following data at hand:
Converter model.
„
Serial number, manufacturing date and hardware revision indicated on the nameplate of the product
„
(see Chapter 2 GENERAL INFORMATION on page
Installed software version (see P0023).
„
Application and programming data.
„

6.5 PREVENTIVE MAINTENANCE

DANGER!
Always disconnect the general power supply before touching any electrical component connected
„
to the converter.
High voltages may still be present even after disconnecting the power supply.
„
Wait at least 10 minutes for the complete discharge of the power capacitors.
„
Always connect the equipment frame to the protective earth (PE) at the proper terminal.

ATTENTION!
Electronic boards have components sensitive to electrostatic discharges.
Do not touch the components or connectors directly. If necessary, first touch the grounded metallic
frame or wear a grounding strap.
When installed in proper environments and operating conditions, the converters require little maintenance.
6.3 on page 6-8 presents the main procedures and time intervals for preventive maintenance.
6-9 contains the recommended inspections to be performed every 6 months after the start-up.
Maintenance
HMI battery replacement
Fan replacement (UP11 G2)
Fill up the cooling fluid with the corrosion
inhibitor CorteC VpCI-649 (UP11W G2)
Clean the cooling system and change the
coolant (UP11W G2)
(1) The converters are programmed at the factory for automatic control of the fans (P0352 = 2) so that they only start when the temperature of the heatsink
increases. Therefore, the number of operating hours of the fans will depend on the operating conditions (motor current, output frequency, temperature of
the cooling air, etc.). The converter records in parameter P0045 the number of hours that the fan remained running. When the fan reaches 50,000 hours of
operation, the HMI display will show alarm A177.
