2. Assemble the AC field plug (see Section 6.4, page 33).
3. Plug the free end of the AC cable connected to
the inverter into the pin connector of the
assembled AC field plug.
☑ The AC field plug snaps into place. The catch mechanisms of both plugs must be correctly
aligned.
Cabling with Junction Box
As an alternative to the AC field plug, you can use a junction box with feed-through terminal for the
connection of the inverter AC cable to the Sunny Multigate. For the assembly and connection of the
AC cable, follow the instructions of the junction box manufacturer.

Cable requirements:
☐ The same cable requirements that apply to the use of the AC field plug also have to be
complied with in this case (see Section 6.4 "Assembling the AC Field Plug", page 33).
Procedure:
1. Cut off the free plug at the end of the AC cable of the inverter.
2. Assemble the AC cable and connect it to the junction box as described by the junction box
manufacturer.
6.6.2 Connecting the AC Cable to Sunny Multigate
Connect the free end of the AC cable coming from the AC field plug or the junction box to the
connecting terminal plate of the Sunny Multigate. The connecting terminal plate assigned for this is
labeled Inverter.
Requirement:
☐ The Sunny Multigate must be correctly installed in the distribution box.
