2) Mounting the molded-case type of smoothing capacitors

(note)This feature to remove the smoothing capacitor easily is not available for the mold case type(up to 11Kw) <1> Place the capacitor unit on the capacitor mounting plate.

<2> Fit both edges of the capacitor mounting plate into the guide grooves in the inverter casing, and then insert the plate into the inverter.

<3> Secure the capacitor board to the main circuit terminal block by using the connection terminal screws. <4> Fix the capacitor mounting plate to the inverter casing by using the screws.

<5> Mount the backing plate.

<6> Mount the terminal block cover.

3)Removing the sheet-metal-case type of smoothing capacitors <1> Remove the terminal block cover.

<2> Make sure that the Charge lamp goes off.

<3> Remove the lower screws from terminal block terminals P and N. <4> Remove the screws fixing the capacitor mounting plate.

<5> Pull down the capacitor mounting plate.

<6> Remove the busbar and resistors, and then remove the capacitor unit from the capacitor mounting plate.

4)Mounting the sheet-metal-case type of smoothing capacitors

<1> Set the capacitor unit on the capacitor mounting plate and secure the unit in place by using the screws.

<2> Mount the busbar and resistors in the original positions, and then secure these parts in place by using the screws. <3> Fit the capacitor mounting plate into the inverter casing.

<4> Fix the capacitor mounting plate to the inverter casing by using the screws. <5> Attach the lower screws to terminal block terminals P and N.

<6> Mount the terminal block cover.
