Connecting DC Conductors from the PV System Array

The DC input terminals provided in the disconnect accept up to 6 AWG

multi-stranded conductors from the PV system array.

Check the polarity and the open-circuit voltage on the conductors

coming from the PV arrays before connecting the DC conductors to the

disconnect’s terminals. Applying an open-circuit DC-input voltage that

exceeds the maximum DC-input-voltage range will cause irreversible

damage to the inverter and void the warranty. Use the online string

calculator at www.pvpowered.com to determine the correct string

conguration.

WARNING

Before proceeding with the DC wiring, completely cover the

surface of all PV panels with opaque material to avoid the

production of electrical energy.

AVERTISSEMENT

Avant de procéder à la connexion du CC, couvrir entièrement

la surface de tous les panneaux PV d’un matériel opaque an

d’éviter la production d’énergie électrique.

WARNING

Make sure the grounding scheme and the PV panel voltage

between the positive and the negative cable connectors of the

PV panels are correct before connecting the panels to the DC

terminal block on the power distribution board.
