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

NOTICE:

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