1.3.3Detaching the terminal board front cover

Detach the front lower cover for wiring, following the steps below.

■Less than 22kW

①②

Remove the two screws at the lower part of the front cover.

Hooked

To detach the cover, draw the terminal board cover

toward you while swinging it up a little.

* For a 30kW model or larger, detach the whole front cover for wiring.
