Caution for UL/cUL requirement
[Available only for the products with UL/cUL mark]
CAUTION
1. [WARNING] Take care of electric
shock. Be sure to turn the inverter off
before starting work.
2. [CAUTION] When the charge lamp is lit,
the inverter is still charged at a
dangerous voltage.
3. [WARNING] There are two or more live
parts inside the inverter.
4. The inverter is approved as a part used
inside a panel. Install it inside a panel.
5. Perform wiring to the input, output and
control terminals of the inverter, referring
to the table below. Use UL certified round
crimp terminal to the input and output
terminals with insulation cover or
covered with reduced tube to obtain the
insulation distance. Use a crimping tool
recommended
manufacturer when fabricating crimp
terminals.
6. Install a fuse or circuit breaker between
the power supply and the inverter,
referring to the table below.
1) Use copper wires of allowable
maximum temperature 60 or 75
degree C.
2) Use UL certified AC600V "Class J
fuse."
