user’s manual inverter SE3.3Ni - SE3.8Ni - SE4.6Ni
CAUTION!
Polarities of each DC input voltage from a PV string shall be precisely correctly connected to the “+” (positive) and “–” (negative)
terminals of a pair respectively. The DC voltage must be less than 500V in any condition.
• The “+” cable of the DC input voltage shall be connected to the terminal labeled “+” and the “-” cable of the DC input voltage shall be connected
to the terminal labeled “-”.
WARNING!
Route the DC connection cables to the SE inverters away from any possible hazards that could damage the cables.
WARNING!
Hazardous voltage is still present on the device after disconnection of all PV DC inputs. Allow 5 minutes for the inverter to discharge
the energy completely.
