5.6.3 Connection Procedure of One Wire per Phase with Multi-core Cable
This section introduces the connection steps with four-core cable as an example,
and the wiring method for three-core cable is the same.
step 1 Disconnect the AC-side circuit breaker and prevent it from inadvertent reconnection.
step 2 Loosen the two screws on the front cover of the junction box with the hexagon socket
wrench provided. Open the junction box. During the wiring process, the limit rod attached to
the cover keeps the junction box open.
The screws on the front cover of the junction box are captive screws, which will re-
main on the front cover when the cover is open to avoid screw loss.
step 3 Loosen the screws on the bottom sealing plate with the hexagon socket wrench provided
and remove the bottom sealing plate.
