user’s manual inverter SE2.8i - SE3.8i - SE4i - SE5i

Connection of the AC cable

WARNING!

Reconfirm the circuit breaker connected to the main utility is switched OFF before connecting the power cable from the breaker
to the AC connector.

Connection of the DC cable

CAUTION!

Identify the different polarity of DC voltage on each PV string and connect respectively to the input terminals marked “UNGROUNDED
CONDUCTOR” and “GROUNDED CONDUCTOR”. Make sure the DC voltage that PV arrays generate is equal to or less than
600 VDC in any case.

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 five (5) minutes for the inverter to
discharge the energy stored in capacitors completely.

WARNING!

PV arrays will be energized when exposed to light. Cover the arrays with opaque (dark) materials during installation and wiring.
