NOTE: In the PVP1100 units the Line 1 conductor is the only
phase voltage wire and Line 2 is neutral.

Figure 4-7 Disconnect’s AC Conductor Connections:
EGC, Line 1 and Line 2
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
configuration.
!
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 afin
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.
