    NOTE:

    Do not measure the voltage or waveform on the sealed side of the inverter with converter assembly connector. Doing so may damage the connector because the connector is waterproof.

  1. *1 Inverter with Converter Assembly

    HINT: 

    Since the inverter with converter assembly uses waterproof connectors, the voltage and waveforms cannot be inspected directly. Standard voltage readings and waveforms are indicated for reference only.
