It is recommended to use a special open-
end spanner for the MC4 DC connectors if
you need to disconnect MC4 DC connec-
torsfromtheinverter.Otherwiseyoumight
destroy the DC connectors.
DANGER
Risk of death or serious injury from electrocution
PotentiallyfatalvoltagemaybeappliedtotheDCconnectionsofthesolarin-
verter. 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 Disconnection switch to position OFF.
► MakesuretheDCconnectionscannotbeaccidentallytouched.
► CheckthepolarityoftheDCvoltagebefore
you connect the solar modules.
► To ensure protection degree IP65, cap all
unused connectors with the caps delivered
with the inverter.
