NOTICE
BEFORE INSTALLATION
Check for damage to equipment and packaging. If in

WARNING
INSTALLATION
For optimum safety, follow the steps described in this
document. Keep in mind that the inverter has 2 voltage-
carrying sides; the PV input and the AC grid.
DANGER
DISCONNECTING THE INVERTER
Before starting work on the inverter, switch off AC at the
mains switch and PV using the PV load switch. Ensure
that the inverter cannot be unintentionally reconnected.
Use a voltage tester to ensure that the unit is discon-

with very high voltage at hazardous levels even when it
is disconnected from AC grid and solar modules. Wait at
least 5 minutes following disconnection from grid and
PV panels before proceeding.
