INSTALLATION INSTRUCTIONS

STEP1: DC CONNECTION

IMPORTANT: ALWAYS CONNECT DC FIRST. DO NOT ENERGIZE AC BUS TO

INVERTERS UNTIL ALL INVERTERS HAVE BEEN DC POWERED WITH

ENOUGH SUN LIGHT (LED code continuously blinking)

STEP2: AC CONNECTOR – INSTALLATION PROCEDURE

IMPORTANT: all MCB connections must be placed with care not to miss-align. All connectors

are keyed to ensure properly polarity.

1) Place the modular branch connector (MBC) on the inverter

FIRST. This will make it easier to align the small pins on the

inverter with the connector. They self-align and are keyed.

2) Join the larger connector of the MBC to the T-Junction of the

modular trunk cable (MTC).
