Grid output connection (AC side)
Wire must be sized based on ampacity requirements of the NEC or other applicable prevail-
ing code.
To prevent electrocution hazards, all the connection operations must be carried out with the
external AC disconnect switch downstream of the inverter (grid side) open and locked out.
Any failure of the inverter when it is not connected to ground through the appropriate terminal
is not covered by the warranty.
AC grid wiring is based on the grid standard shown in the utility congur-
ation table below.

Connection to AC terminal block
- Run an approved raceway between inverter and external AC OCPD.
- Remove the threaded plastic plug and nut from the AC cable opening
14
.
- Insert the appropriate water-tight conduit connector and tighten to the
chassis to maintain NEMA 4X compliance.
- Make appropriate conduit runs from grid and pull the AC conductors
through the raceway to the inverter.
Conduit must be sealed using water-tight ttings to maintain NEMA Type 4X enclosure integrity.
- Connect the conductors to the correct terminals on the AC output ter-
minal block
10
(wire size range of 20-6 AWG) based on the AC grid
standard used in the table above.
