Section C - Wiring
Control (CTRL) wiring
between system components
Control wiring guidance for the Enphase Energy System:
Refer to the following wiring sequences to understand the position
of the header with termination resistor, wiring order, and drain wire
termination location.
NOTE: The cumulative length of CTRL wiring across the system
cannot exceed 250 feet to ensure the system operates as per
specications.
NOTE: Ensure these guidelines are followed to avoid failures during
system commissioning:
One header with a termination resistor should be installed
on each component that is at the extreme end of the control
network.
The drain wire should only be terminated on one end of the
control wiring between system components.

It is recommended that the drain wire be terminated at the
component from which control wiring for the section is
initiated.
The same conduits can be used for power and control wire
routing only when using an Enphase CTRL cable, i.e., CTRL-
SC3-NA-01.
