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 AC/DC isolating 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
