Fig. 10-6 Diagram for replacing the cooling fan
Caution!
The cooling fans have different models according to power levels,
which shall be noted.
The installation of the fan power & cable interface shall be finished
before fastening the cooling fan screws.
8. Power Unit Maintenance
Take power unit out of MVD or an insulated plastic bag.
Place power unit on an insulated location. (withstanding voltage level must exceed
input power)
Electrical connection: three-phase power connected to three-phase current-limiting
resistor, and then connect power unit input terminal. Current-limiting resistor and
connection of electrical connection are shown in figure 10-7 and 10-8. (different
power units may have different mechanical designs, as for electrical connection
please choose the hung-up side of fuse)
