Requirements if power is supplied from an external source
The following requirements apply if power is fed from an external power source:
The allowed diameter of shielded or jacketed cables is 6-25 mm (0.24-1 in.).
•
•
The allowed cross section of individual DC wires is 6-25 mm
terminal. It is recommended that 25 mm
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.
