A problem that might
occur
This manual contains important instructions that must be
followed during installation and maintenance of the
inverter.
Before Installation
Check the inverter and the packaging for damage.
If in doubt, contact the supplier before commencing
installation.
Installation Service
For optimum safety, follow the steps described in this
document. Keep in mind that the inverter has two voltage
carrying sides, the PV input and the utility grid.
Disconnecting the inverter
Before working on the inverter, disconnect it from the utility
grid by means of the AC breaker and switch off PV using
the integrated PV load-break switch (DC load-break
switch). Ensure that the inverter cannot be unintentionally
reconnected. Use a voltage detector to ensure that the
unit is disconnected and voltage free. The inverter can still
be charged with very high voltage at hazardous levels
even when it is disconnected from utility grid and PV
modules. Wait at least five minutes after disconnection
from the utility grid and PV modules before proceeding.
