Notes:
The specified wire length is for a pair of conductors from the solar, load or battery
source to the controller (1-way distance).
Figures are in meters (m) and feet (ft).
For 24 volt systems, multiply the 1-way length in the table by 2.
For 48 volt systems, multiply the 1-way length in the table by 4.
Ground Connection:
Use the grounding terminal in the wiring compartment to connect a copper wire to an earth
ground or similar grounding point. The grounding terminal is identified by the ground
symbol shown below that is stamped into the enclosure:
