INFORMATIONS!
Conduit ttings need to be water tight with either NEMA 4, 4X, 6, or 6X rated, and insulated type
preferred.
Once conduit and ttings are installed, route wiring thru conduit and tting and allowing a 6 inch
strain relief loop within the wiring box compartment.
Potential AC voltage loss in AC wires is possible to determine for a given wire cross section
and wire length. Pages 59 and 60 contain diagrams for each M series solar inverter model to
help determine the best wire size for your particular installation. Delta recommends you select
a wire size and length to ensure a maximum voltage loss between 1 - 2 %. Please note that the
diagrams only o󰀨er approximate voltage loss and more precise voltage loss should be calculated
by a licensed electrician in accordance with local, state, and National Electrical Code ANSI/NFPA
70 requirements.
