Connecting the AC Cable to the AC Field Plug or to the Junction Box

There are two ways to connect the first inverter to the Sunny Multigate on the AC side:

  • Connection with the AC field plug included in the delivery

  • Connection via a junction box with integrated feed-through terminal

Procedure:

  1. DANGER

    Danger to life due to electric shock

    Do not connect the AC field plug under load.

    1. Make sure that the two-pole circuit breaker of the Sunny Multigate is switched off and cannot be reconnected.
    2. Make sure that the PV modules are covered.
  2. Assemble the AC field plug ( > Assembling the AC Field Plug).

  3. Plug the free end of the AC cable connected to the inverter into the pin connector of the assembled AC field plug.
  4. 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.

All electrical installations must be carried out in accordance with the locally applicable electrical standards and the National Electrical Code® (NE, ANSI/NFPA 70) (see National Electrical Code®, paragraph 690.8 (B)(1), paragraph 690.8(A)(3)).
