General safety instructions
1
DANGER
Risk of death by electrocution
Potentially fatal voltage is applied to the solar
inverter during operation. This potentially fatal
voltage is still present for 80 seconds after all
powersourceshavebeendisconnected.
►Never open the solar inverter.
►Always disconnect the solar inverter from
powerbeforeinstallation,opentheAC/DC
isolating switch and make sure neither can
beaccidentallyreconnected.
►Wait at least 80 seconds until the capacitors
have discharged.
DANGER
Risk of death or serious injury from elec-
trocution
Potentiallyfatalvoltagemaybeappliedtothe
DC connections of the solar inverter. When light
is falling on solar modules, they immediately start
producing energy. They do so, even when the
sun is not shining.
►Never disconnect the solar modules when the
solar inverter is powered.
►First switch off the grid connection so that
the solar inverter cannot feed energy into the
grid.
►Turn the DC disonnecting switch to position
OFF.
► MakesuretheDCconnectionscannotbe
accidentally touched.
● Thesolarinvertercanbesafelyandnormallyoperatedif
installed and used in accordance with this manual (see
IEC62109-5.3.3).DeltaEnergySystemsisnotresponsible
fordamageincurredbyfailuretoobservetheinstallationand
operatinginstructionsinthismanual.Forthisreason,besure
toobserveandfollowallinstructions!
● Installationandcommissioningmayonlybeperformedby
qualiedelectriciansusingtheinstallationandcommission-
ing instructions found in this manual.
● Thesolarinvertermustbedisconnectedfrompowerandthe
solarmodulesbeforeanyworkonitcanbeperformed.
●The solar inverter has a high leakage current value. The
ground wire mustbeconnectedbeforecommissioning.
●Do not remove any warning signs that the manufacturer has
installed on the solar inverter.
●Improper handling of the solar inverter may result in physical
injuryanddamagetoproperty.Forthisreason,observeand
follow all general safety instructions and warnings.
● Thesolarinvertercontainsnocomponentsthatmustbe
maintainedorrepairedbytheoperatororinstaller.Allrepairs
mustbeperformedbyDeltaEnergySystems.Openingthe
cover will void the warranty.
● Donotdisconnectanycableswhenthesolarinverterispow-
ered due to risk of a fault arc.
●To prevent lightning strikes, follow the relevant regulations
applicableinyourcountry.
● Thesurfaceofthesolarinvertercanbecomeveryhotdur-
ing operation. Use safety gloves when working on the solar
inverter.
● Thesolarinverterisveryheavy.Thesolarinvertermustbe
liftedandcarriedbyatleasttwopeople.
● OnlydevicesincompliancewithSELV(EN69050)maybe
connected to the RS485 and USB interfaces.
● Allconnectionsmustbesufcientlyinsulatedinordertocom-
ply with the IP65 protection rating. Unused connections must
beclosedbyplacingcovercapsonthesolarinverter.

► Ensureadequateaircirculation.Hotairmustbeable
to dissipate upward. Keep enough space around each
inverter.
► Donotinstallinvertersdirectlyaboveoneanother.
Otherwise,theupperinverteriswarmedupbythe
lower one.
►Consider the operating temperature range (see sec-
tion“Technicaldata”).
When the operating temperature range is exceeded,
the solar inverter reduces the amount of power gener-
ated.
Ambient temperature and air circulation
Outdoor installations
►The solar inverter has protection
degree IP65 and can be installed
indoors or in protected outdoor
areas(thatmeansoutdoorbut
