AC Wire Assembly and Connection
Danger to Life due to High Voltages in the Inverter
Before connecting any electrical wires and components, please ensure the DC switch & AC circuit
breaker are switched OFF and cannot be reactivated.
DANGER
DC Wire Assembly and Connection
Meeting the following requirements is mandatory. All warranty rights will otherwise be invalid.
3.3.1 Maximum open voltage of each string is less than 1100V.
3.3.2 Maximum short circuit current of each PV input is less than inverter allowable limit.
3.3.3 The string is well insulated to ground in all cases.
3.3.4 Make sure that the DC connectors have the correct polarity.
3.3.5 If the PV connectors are not assembled properly and locked into place, arc or overheat may be
induced.

1. The inverter and mounting bracket have been correctly installed. 2. The inverter’s exposed metal
surface has a ground connection. 3. The resistance between PV arrays and ground is greater than
1Mohm. 4. For any unused DC terminals, there are DC connectors inserted to the terminal and
sealed with waterproof caps. 5. The grid voltage at the point of connection of the inverter is within
the permitted range. 6. The AC circuit breaker must be correctly rated and wired. 7. The cable
communication connectors have been correctly wired and tightened.
Startup
Switch on the DC switch after finishing the above checks, then switch on the AC circuit breaker.
When there is sufficient DC power applied and the grid conditions are met, the inverter will start to
operate automatically.
