    Energization and Start-Up 5.7 OPERATION WITH A REDUCED NUMBER OF POWER UNITS The CFW11W G2 can operate with a reduced number of UP11W G2 and reduced power for a short time. That operating mode is called "Reduced Power Mode". It may be applied to critical processes in which you do not want a whole machine to stop when one UP11W G2 fails, enabling the operation with reduced power until you have a UP11W G2 for replacement.

    Do not touch the components or connectors directly. If necessary, first touch the grounded metallic frame or wear a ground strap. Do not execute any applied potential test on the inverter! If necessary, contact WEG. When installed in proper environment and operating conditions, the inverters require little maintenance. Table 6.3 on page 6-12 presents the main procedures and time intervals for preventive maintenance.
