General safety instructions

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

protectedbyaroofagainstdirect

sun,rainorsnow).

andthatthebuttonscanbeoperated.

Make sure the reading angle and instal-

lationheightaresufcient.

►Always use the mounting plate

supplied with the solar inverter.

► Checkthatthewalliscapable

ofbearingtheheavyloadofthe

device.

►Use dowels and screws that are

suitableforthewallmaterialand

the heavy weight.

►Mount the solar inverter on a

vibration-freewalltoavoiddisrup-

tivevibrations.

► Possiblenoiseemissionscan

bedisruptivewhenthedeviceis

usedinlivingareasorinbuildings
