Step 5: Manage the Cabling
A. Use cable clips or tie wraps to attach the cable to the racking. Leave no more than 1.8 m (six
feet) between cable clips or tie wraps.
Cable clip
B. Dress any excess cabling in loops so that it does not contact the roof. Do not form loops
smaller than 12 cm (4¾ “) in diameter.
WARNING: Tripping Hazard. Loose cables can become a tripping hazard. Dress the
Enphase Q Cable to minimize this potential.
Step 6: Connect the Microinverters
A. Connect the microinverter. Listen for a click as the connectors engage.
B. Cover any unused connector with Enphase Sealing Caps. Listen for a click as the connectors
engage.
WARNING: Risk of electric shock. Risk of fire. Install sealing caps on all unused AC
connectors as these connectors become live when the system is energized. Sealing caps
are required for protection against moisture ingress.
NOTE: If you need to remove a sealing cap, you must use the Enphase Disconnect Tool.
See “Disconnect a Microinverter” on page 25.
