General Safety

All persons installing and servicing inverters must be:
•
Trained and experienced in general safety rules
for work on electrical equipment.
•
Familiar with local requirements, rules and
regulations for the installation.
NOTICE
Before installation
Check for damage to equipment and packaging. If in
doubt, contact the supplier before commencing instal-
lation.
CAUTION
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.
WARNING
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 device cannot be unintentionally reconnected.
Use a voltage tester to ensure that the unit is discon-
nected and voltage free. The inverter can still be charged
with very high voltage at hazardous levels even when it
is disconnected from AC grid and solar modules. Wait at
least 8 minutes following disconnection from grid and
PV panels before proceeding.
For safe disconnection of DC current, turn off the PV load
switch (1).
CAUTION
Maintenance and modification
Only authorised personnel are permitted to modify the
inverter. To ensure personal safety, use only original
spare parts available from the supplier. If non-original
spare parts are used, compliance with CE guidelines in
respect of electrical safety, EMC and machine safety is
not guaranteed.
The temperature of the cooling racks and components
inside the inverter can exceed 70 ºC. Observe the danger
of burn injury.
DC voltages up to 1000 V are present in a PV system even
when the inverter is disconnected from the AC grid. Faults
or inappropriate use may lead to electric arcing.
WARNING
PV modules generate voltage when exposed to light.
