Attach the Microinverters to the PV Racking
a. Mark the approximate centers of each PV
module on the PV racking. See notes in Step
Details.
b. Mount the microinverter under the PV mod-
ule, away from rain and sun. Do not mount the
microinverter in a position that allows long-term
exposure to direct sunlight or in a vertical orienta-
tion that allows water to collect in the DC connec-
tor recess.
c. Torque the microinverter fasteners as follows. Do
not over torque:
• 5 N m (45-50 in-lbs) for 6 mm (1/4") hardware
• 9 N m (80-85 in-lbs) for 8 mm (5/16") hardware

7 Connect the Microinverters
a. Remove and discard the temporary shipping
cap from the cable connector and connect the
microinverter. Listen for two clicks as the
connectors engage.
b. Cover any unused connectors with Enphase
Sealing Caps. Listen for two clicks as the con-
nectors engage. See notes in Step Details.
Do not use shipping caps to cover
unused connectors. The shipping cap
does not provide an adequate
environmental seal.
NOTE: Enphase integrated ground microin-
verters meet the requirements of NEC 690.35.
Because the DC circuit is isolated and insulated
from ground, the M215-60-2LL-xxx-IG does not
require a GEC. Ground fault protection (GFP) is
integrated into the microinverter. For details, refer
to "Microinverters with Integrated Ground"
