your

required. The box includes pre-drilled mounting holes.
Recommend Wire Size
4 AWG for COM6IN-120AO

*Length of output wire must be calculated with voltage as to not get significant voltage drop.
Connections
PV output breaker must be in the OFF position before making any connections to combiner box.
Connect earth ground before any other connection
Make
sure all output connections are properly fastened to the combiner box and device. PV input
connection should be made last. Before turning output breaker to the ON position, voltage must
be tested on input side of breaker to be within specification of connected device. After PV voltage
is confirmed to not exceed the device’s input rating the breaker is safe to turn on.
