NEP BDM-600 - INSTALLATION; Pre-installation; System Layout; Connect Wiring Harnesses

Step 2 – Connect the Wiring Harnesses
Each BDM-600 comes with an integrated trunk cable to simplify the AC
connecon process. The AC trunk cable includes a male connector on one end
and a female connector at the other end. Plug the male AC connector of the rst
BDM-600 into the connector on the tail cable. Plug the female AC connector of
the rst BDM-600 into the male connector of the next BDM-600 (or jumper
cable) and connue this “daisy chain” process to form a connuous AC branch
circ
uit. Terminate the nal female connector on the last microinverter in the
branch circuit with the protecve cap. The connectors are keyed with a snap lock
pin. A “click” indicates proper mang. Secure the mated connector pairs and any
excess AC cable to the rail or racking using cable clips or wire es
WARNING:
DO NOT EXCEED THE MAXIMUM NUMBER OF SEVEN (7) BDM-600s IN A
240V AC BRANCH CIRCUIT (SIX(6) FOR 208V) AND EACH BDM-600 AC BRANC
H CIRCUIT
MUST BE SOURCED FROM A 20A MAXIMUM BREAKER.
Install a protecve end cap on the open female AC connector on the last
microinverter at the end of the truck cable.
WARNING:
MAKE SURE PROTECTIVE END CAPS HAVE BEEN INSTALLED ON ALL UNUSED
AC CONNECTORS. UNUSED AC BDM-600 WIRE HARNESS CONNECTORS ARE LIVE WHEN
THE SYSTEM IS ENERGIZED BY T
The AC branch circuit should look as pictured below:
6.2 Installa�on Steps
WARNING: CONNECT BDM-600S TO THE ELECTRICAL UTILITY GRID ONLY AFTER RECEIVING
PRIOR APPROVAL FROM THE UTILITY COMPANYAND LOCAL AHJ.
WARNING: BE AWARE THAT ONLY QUALIFIED PERSONNEL CAN CONNECT BDM-600 TO
THE ELECTRICAL UTILITY GRID.
Step 1 – System Layout
Mark the approximate locaon of each pair of PV modules on the racking system.
Place the microinverters at the locaon called out in the layout map and loosely
 to the rails using the MLPE clam
ps. Check the reach of all DC and AC
cabling. DC jumpers may be required for some modules. Reposion as needed.
WARNING:
ALLOW A MINIMUM OF 2.75 INCHES BOTH BETWEEN THE TOP OF THE
ROOF AND THE BOTTOM OF THE BDM-600 AND BETWEEN THE BACK OF THE PV MODULE
AND THE TOP OF THE BDM-600. DO NOT PLACE THE BDM-600 IN A LOCATION SUBJECT TO
DIRECT SUNLIGHT.

For ground mount, ballasted, or at roof deployments it may be necessary to
the microinverters to the racking frame.
Once thenal posion is conrmed, secure the microinverters using the MLPE
clamps and torque per the manufacturer’s specions. Typical values are about
lbs (16.3 NM).
