Chapter 8 Maintenance And Inspection; T Daily Inspections - V&T E5 Series User Manual

The application environment (such as temperature, humidity, dust and powder, wool, smoke and
oscillation), burning and wearing of internal devices and other factors may reduces the service life. To
reduce the fault and prolong the service life, it is necessary to perform daily inspections and periodic
maintenance.
Note Note
T. Only the professionals can dismantle and replace the components.
T. Before inspection and maintenance, please make sure that the power supply to the has been shut
down for at least ten minutes or the CHARGER indicator is OFF, otherwise, electric shock may be
happened (E5−H−4TTTG and above power class, E5−A−4TT5 and above power class has CHARGER
indicator).
3. Do not leave metal components and parts in the inner of inverter, otherwise, inverter me be damaged.
