enphase IQ Battery 10C Quick Install Manual page 23

NOTE: The ends of Interconnect power cables are labeled with the battery unit location (user-side/wall-side) and respective
terminal (L1/L2). Insert the cables into their respective terminals (as per the label) for accurate and hassle-free installation.
10.2 Connecting the interconnect control cable
NOTE:
• The interconnect control cable comes with one preinstalled connector on one end, while the other end is left free for easy
routing through the raceway adapter.
• Power and control interconnect cables will run through left and right side raceways respectively.
1. Route interconnect control cable through the right side raceway adapter.
2. The interconnect control cable comes stripped on one side and with a preinstalled connector on the other side. Connect the
stripped end of the interconnect control cable to the control connector from the accessory kit (torque to 1.8 in-lb or 0.2 N m).
3. Connect the control connectors installed at the two ends of the interconnect cable on the control communication boards of the
wall-side and user-side units.
4. For additional information on control wiring and to remove or add/keep a resistor on the control connector, refer to the section -

10.3 Wiring the Control (CTRL) cable between system components
NOTE:
• The control cable must comply with UL 3003, UL 1277, and UL 83 standards. The Enphase control cable (SKU: CTRL-SC3-
NA-01) has optimal impedance and has been validated for optimal system performance. Third-party cables may not have
the correct characteristic impedance, and consequently, may not work reliably. Enphase cannot guarantee performance
when a third-party control cable is used.
• The same conduits can be used for power and control cable routing only when using an Enphase Control Cable.
• Refer to the CTRL wiring C1/C2 label available on the product for easy reference.
• Each component at the extreme end of the control network should have one header with a termination resistor installed.
