5.6.4 Connection Procedure (For a single-core cable)

step 1 Disconnect the AC-side circuit breaker and prevent it from inadvertent reconnection.

step 2 Loosen two screws on the front cover of the junction box using the supplied hexagon socket

wrench, and open the junction box. Keep the cover of the junction box open during wiring
with a limit rod attached to the cover.

The screws on the front cover are captive screws. When the front cover is opened,

the screws remain on it.

step 3 Loosen screws on the bottom sealing plate using the supplied hexagon socket wrench, and

remove the sealing plate.
