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
Safety Message Types
WARNING
Safety information important for human safety. Warnings
are used for indicating potentially hazardous situations
that can cause serious injury or death.
CAUTION
Cautions with symbol are used for indicating potentially
hazardous situations that can cause minor or moderate
injuries.
CAUTION
Cautions without symbol are used for indicating situations
that may result in equipment or property damage.
NOTE
Note is used for indicating highlighted information that
should be regarded with attention.
General Safety
NOTE
Before installation
Check for damage to inverter and packaging. If in doubt,
contact the supplier before installing the inverter.
CAUTION
Installation
For optimum safety, follow the steps described in this
manual. Keep in mind that the inverter has two voltage
carrying sides; the PV input and the AC grid.
WARNING
Disconnecting the inverter
Before starting work on the inverter, switch off AC grid 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 disconnected
and voltage free. The inverter can still be charged with
very high voltage at hazardous levels even when it is
disconnected from grid/mains and solar modules. Wait at
least 30 min. following disconnection from grid and PV
panels before proceeding.
CAUTION
Maintenance and modification
Only authorised personnel are allowed to repair or modify
the inverter. To ensure personal safety, only original spare
parts available from the supplier should be used. If nonoriginal spare parts are used, the 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 may exceed 70ºC. Observe the danger
of burn injury.
CAUTION
Functional safety parameters
Never change the parameters of the inverter without
authorisation from the local energy supply company and
instructions from Danfoss.
Unauthorised changes of functional safety parameters may
cause injury or accidents to people or inverter.
Additionally, it will lead to the cancellation of all inverter
operating approval certificates and Danfoss warranties.
Danfoss cannot be held responsible for such injuries or
accidents.

Hazards of PV Systems
DC voltages up to 1000 V are present in a PV system even
when the AC grid is disconnected. Faults or inappropriate
use may lead to electric arcing.
WARNING
Do not work on the inverter while disconnecting DC and
AC.
The short-circuit current of the photovoltaic panels is only
slightly higher than the maximum operating current and
depends on the level of solar irradiation.
PV Load Switch
The PV load switch (1) enables safe disconnection of DC
current.
