NOTICE
The PV load switch can be secured in the ‘Off’ position
using a padlock.
CAUTION
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.
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/UL guidelines
in respect of electrical safety, EMC, and machine safety is
not guaranteed.

CAUTION
The temperature of the cooling racks and components
inside the inverter can exceed 70 °C/158 °F. Observe the
danger of burn injury.
The inverter is to be installed so that it is not expected
to be contacted by persons.
