WARNING!
Select PV modules with excellent function and reliable quality.
Open-circuit voltage of module arrays connected in series should
be less than inverter Max. DC input voltage of 500V.
Inverter warranty is VOID if the DC input voltage exceeds the inverter
600V maximum.
WARNING!
Ensure no live voltages are present on PV input and AC output
circuit, and verify that the DC disconnect, AC disconnect, and
dedicated AC circuit breaker are in the “OFF” position, before
installation.
WARNING!
Please use a dark opaque sheets to cover the PV solar panels before
any wiring or connecting.
NOTE!
The PV connection mode below is NOT allowed!

WARNING!
Power is fed from more than one source, and more than one live
circuit.
Please note that all DC and AC terminals may carry current even
without connected wires.
WARNING!
Ensure maximum protection against hazardous contact voltages
while assembling PV panels installations. Both the positive and
negative leads must be strictly isolated electrically from the
protective ground potential (PE).
CAUTION!
Never reverse the polarity of the array string cables as it can damage
to the inverter. Always ensure correct polarity.
Step 1: Choose the appropriate wire according to the specific connection.
Step 2: Remove 0.47in/12mm of insulation from the end of DC wire( the AC wire
shall be removed by 0.71in/18mm).
Step 3: Insert the end of wires into the Cord End Terminal, and then use the
crimping pliers to crimp the Cord End Terminal tightly (the shape will be square).
Step 4: Use the slot screwdriver to compress the orange button of the terminals.
Then insert stripped wires into the terminal and ensure that all conductor
strands are captured in the terminal.
Step 5: Loosen the slot screwdriver.
