*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.

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.
