Wiring cover and Handling (FR-F720-00930 (FR-F740-00620) or less)
1) Remove the wiring cover of the inverter. Punch out a knockout by firmly tapping it with such as a hammer. Remove
any sharp edges and burrs from knockout holes of the wiring cover.
2) Install conduits and fix with conduits clamps. Pass the cable always through the conduit.
CAUTION
When handling the wiring cover, care must be taken not to cut fingers or hands with sharp edges and burrs.
To avoide wire offcuts and other foreign matter to enter the inverter, conduits must be installed to the all knockout holes.
Do not wire without using conduits. Otherwise, the cable sheathes may be scratched by the wiring cover edges,
resulting in a short circuit or ground fault.
REMARKS
⋅ When using conduits for the FR-F720-00046 and 00077, fix the conduits to the wiring cover after connecting the earth cable to
the inverter earth terminal.
