Safety instructions
WARNING
Electric shock from the live inverter
housing
The inverter has a conductive metal hous-
ing.
►
Always ground the inverter housing
before
connecting the inverter to the
grid and solar modules.
►
Always ground the inverter housing
before
connecting the inverter to the
grid and solar modules.
►
Always comply with local regulations
relating to grounding cable
requirements.
►
To increase the safety of the system,
always use the grounding screw to
ground the inverter housing even
when this is not required by the local
regulations.
►
The cross-section of the grounding
cable must be at least 6 mm
2
(copper).
WARNING
Hot surfaces
The surface of the inverter can get very hot
during operation.
●
Always wear safety gloves when touch-
ing the inverter.
NOTICE
Incorrectly dimensioned solar system
If the solar system is dimensioned incorrectly, this may
damage the inverter.
►
When calculating the module string, always pay
attention to technical specifications of the inverter
(
input voltage range
,
maximum input current
and
maximum input power
, see "Technical Data").
NOTICE
Overheating of the DC connections
Exceeding the
maximum input current
can cause the
DC connections to overheat and result in a fire.
►
When dimensioning the module strings, always take
into account the
maximum input current
of the DC
connections (see "Technical Data").
NOTICE
Ingress of moisture
Moisture can enter via open DC connectors.
►
To ensure protection degree IP66, close unused DC
connectors with the rubber plugs that are attached
to the DC connectors.
NOTICE
Working in freezing conditions
In frosty conditions, the rubber seal of the front door
can freeze to the enclosure, tear when opened and thus
become leaky.
►
Before opening the front door, defrost the rubber
seal with some warm air.
►
Open the front door slowly.
●

manual. Delta Electronics is not responsible for
damage resulting from failure to follow the safety and
operating instructions set out in this manual.
●
The inverter may only be installed and commissioned
by installers who have been trained and approved for
the installation and operation of grid-connected solar
inverters.
●
All repair work on the inverter must be carried out by
Delta Electronics. Otherwise the warranty will be void.
●
Warning notices, warning symbols and other mark-
ings attached to the inverter by Delta Electronics
must not be removed.
●
To avoid the risk of arcing, do not disconnect cables
when the inverter is under load.
●
To prevent damage due to lightning strikes, follow the
applicable regulations in your country.
● All external connections must be sufficiently sealed in
order to ensure an IP66 protection degree. Seal any
unused connections with the cover caps supplied.
●
Only equipment that complies with SELV (EN 60950)
may be connected to the RS485 interfaces.
