Cooling Fan Fuse
for models 18kw through 160kW
18kW through 160kW Yaskawa GPD 506/P5 and GPD 515/G5 inverters
have a cooling fan fuse for the 230V AC fans. The fuse is located on either
the power supply board or the tap change board (3PCB). If the cooling fan
fuse is open, then the fan(s) may be defective.
The fuse can easily be checked using an ohmmeter set to the R X 1 scale.
Place one lead of the ohmmeter on one side of the fuse, and place the other
lead of the ohmmeter on the other side of the fuse. If the fuse is bad, the
measured value will be infinite ohms.
