Step3. Check correct polarity of wire connection from PV modules and PV input connectors. Then, connect positive pole (+) of connection wire
to positive pole (+) of PV input connector. Connect negative pole (-) of connection wire to negative pole (-) of PV input connector. Screw two
wires tightly in clockwise direction.
Step 4. Make sure the wires are securely connected.
AC INPUT/OUTPUT CONNECTION
• The grid voltage and frequency must be in the permissiblerange.
• An external AC breaker (≥25A@GF1-3K48S1,≥40A@GF1-5K48S1) must be installed between inverter and AC input power source. This will ensure the
inverter can be securely disconnected during maintenance and fully protected from over current of AC input.
• There are two terminal blocks with "IN" and "OUT" markings. Please do NOTmisconnect input and output connectors.
• All wiring must be performed by a qualified personnel.
• Before making AC input/output connection, be sure to open DC protector or disconnectionfirst.
• Disconnect the AC circuit breaker and secure it against reconnection.
Step1: Assembling the AC Connector
• Remove the cable jacket and strip the wire insulation by 5–7 mm
• Insert the conductors to the corresponding terminal and crimp them.
Step 2: Installing the AC Connector
• Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws.
• Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws.
• Connect "PE" conductor to the grounding electrode. Connect "L" and "N" conductors to the AC circuit breaker.
• Make sure the wires are securely connected.
