Board connector check

The board connector check is a quick look to confirm that the logic connector going to the arc fault detection board is properly seated and secure. It is the first recommended step when a CPS or Yaskawa Solectria string inverter reports an arc board error or an arc protection alarm. One manual lists poor contact or damage of the arc board as possible causes of the arc board error, so a loose connector is a likely cause worth ruling out first. Once the connector is secure, run the arc fault test from the Settings menu on the inverter or in the app. If the alarm comes back after the test, the connector was not the cause, and the arc board or wiring box has to be replaced. Some manuals say this replacement should be done through the manufacturer's service team.

<!-- review notes

• sentence 1: support check: partial - Passages say to check the logic connector to the arc board is secure, but don't describe it as a 'quick look' or mention 'properly seated'.
• sentence 3: support check: partial - u26 lists poor contact or damage of the arc board as a possible cause, but the claim that a loose connector is a likely cause to rule out first is an inference not stated.
• sentence 4: support check: partial - Passages say run the Arc Fault Test from the Settings menu (one says in the app), but 'on the inverter' is not stated and 'once secure' ordering is implied only by step order.
• sentence 5: support check: partial - Passages say replace the arc board or wiring box if the alarm re-occurs, but don't state the connector was ruled out as the cause or that replacement is mandatory. -->
