•
The allowed cross section of individual DC wires is 6-25 mm
2
(10-4 AWG) at the DC
terminal. It is recommended that 25 mm
2
(4 AWG) wires are capped to avoid loose
strands. If thicker DC wires are required, then an FSEC/FSES or other IP65 DC
distribution box is required to reduce the cable thickness at the module.
•
Recommended DC cable lengths, thicknesses, and type are provided in the section
Feederless site and Distributed site solution requirements.
•
The DC connector has three screw terminals. The outer terminals are for (+) and (-)
wires. The middle terminal is for grounding the shielded DC cable braid.
