WARNING! It's very important for system safety and efficient operation to use
appropriate cable for PV module connection. To reduce risk of injury, please use the
proper recommended cable size as below.
CAUTION: Do NOT touch the inverter to avoid electric shock. When PV modules are
exposed to sunlight, it may generate DC voltage to the inverter.
