Event, cause and corrective measures

1001

Installation failure grid connection / L/N swapped (1001)
The conductors L and N are swapped or PE is not connected.
Corrective measures:

• Check whether the connecting terminal plates Grid and Inverter of the

Sunny Multigate are correctly assigned.

• If the connecting terminal plates Grid and Inverter are not correctly assigned,

disconnect the Sunny Multigate from all voltage sources (see Section 10, page
50) and connect the conductors L, N and PE correctly.

• Once the connecting terminal plates are correctly assigned, check whether the

AC field plugs or junction boxes between the inverters and the Sunny Multigate
are correctly assembled.

– Disconnect the inverter from all voltage sources (see Section 9, page 48).
– Check the assembling. If present, remove the AC field plug (see

Section 13.1 "Disconnecting the AC Field Plug", page 64) and assemble it
correctly (see Section 6.4 "Assembling the AC Field Plug", page 33).
