DC Connections
The DC input copper bus is located in the lower left corner of the inverter; there are 6
DC inputs in the DC copper bus with OT70 lugs.
Cables rated for a minimum of 600V are required for connecting the inputs of the
inverter.
Because the maximum DC current may reach 340A and the connection
terminals are M8 lugs, at least two AWG 1/0 (70mm
2
) DC input cables for each
DC polarity are required.
The DC cables to be connected must be rated for a minimum of 600V.
Be careful not to connect the wrong DC input polarity.
The voltage of the PV array must never exceed the maximum permissible
inverter input voltage of 600V.
1. Ensure that the DC cables with no electricity.
2. Route the DC cables through the cable entry holes to the DC terminals, see Fig
7-5.
3. Connect the cables to DC (+) and DC (-) terminal on the DC circuit breaker
respectively, refer to Fig 7-1.
4. Attach the DC cables to the terminals using appropriate screws.
