Installation and Commissioning

The DC connector model of the optimizer is Staubli MC4. Ensure that the DC
connectors are of the same model. Otherwise, the connector compatibility
report and third-party lab (TUV, VED, or Bureau Veritas) report from the DC
connector manufacturer must be provided. Using incompatible DC connectors
may result in serious consequences. The resulting device damage is beyond
the warranty scope.
If the optimizer does not connect to any other device, protect it from rain.
Optional scenario: The total open-circuit voltage of all PV modules in a PV
string cannot exceed the maximum inverter input voltage under any
condition.
It is recommended that the positive and negative cables (PV+/PV–) between
the optimizer and inverter be placed in parallel to avoid cable tangling.
The input power cable of the optimizer is connected to the PV module
junction box, and the output power cable is connected to the adjacent
optimizer or inverter. Do not reversely connect the input and output power
cables. Otherwise, the optimizer may be damaged.
Other precautions are listed below.
