TheinverterisnotcapableoffeedinginDCresidualcurrentsdue
toitsdesign.ItfulllsthisrequirementinaccordancewithDIN
VDE0100-712.
ThepossibilitiesoffaultswereexaminedbyDeltawithouttak-
ingtheintegratedRCMU(residual-currentmonitoringunit)into
account. When examining these faults in terms of the current
validinstallationstandards,nodangerincombinationwithatype
Aupstreamresidual-currentdevice(RCD)canoccur.Therefore
faults that would otherwise require the use of a type B residual-
currentdeviceduetotheinvertercanbeexcluded.
The integrated all-pole sensitive RCMU provides additional
safety.RCDTypeAcanbeusedforthisinverter,accordingtothe
followingtable.
M15A M20A
Minimum tripping current of the RCD mA 100 100
NOTE
The value of the tripping current mainly depends
on the quality of the solar modules, the size of
thePVarrayandenvironmentalconditions(e.g.
humidity).
Important information regarding safety AC cable requirements
Use properly sized wires to connect to the correct poles (see

TheACplugdeliveredwiththeinvertercanbeusedwithexible
coppercables.
Read and follow the instructions delivered with the AC plug.
Whencalculatingthecrosssectionofthecable,consider:
● material used
● thermal conditions
● cablelength
● type of installation
● AC voltage drop
● powerlossesincable
Alwaysfollowthesysteminstallationrequirementsdenedfor
yourcountry!
Australia/NewZealand:Alwaysfollowthesysteminstallation
requirementsdenedbyAS/NZS5033:2005regardingminimum
cablesectionsandprotectionsagainstoverheatingduetohigh
currents!
Grounding the inverter
TheinvertermustbegroundedviatheACconnector’sPEcon-
ductor. To do this, connect the PE conductor to the designated
terminal of the AC plug.
Markings on the inverter
Insomecountries,thefollowinglabelshavetobeappliedonthe
frontofeachmicroinverter.Pleasecheckapplicablenationaland
local standards and regulations.
