What does 1030 mean?

This status indicates that a device connected in the Wired Shutdown (WSD) chain has interrupted the signal line, possibly due to a tripped surge protection device (SPD), the removal of an installed bypass, or a missing trigger device. This condition results in the inverter's operating LED flashing red. It prevents normal operation until the WSD chain integrity is restored.

Common Causes

  • A device in the WSD chain, such as a surge protection device, has interrupted the signal line.
  • The bypass installed ex works as standard has been removed from the WSD chain.
  • A required trigger device has not been installed in the WSD chain.
