• Carry out inspection after waiting 5 minutes or longer for units of FRN0115G2S-2G/FRN0060G2□-4G or
lower, or 10 minutes or longer for units of FRN0146G2S-2G/FRN0075G2□-4G or higher after turning OFF
the power. Furthermore, ensure that the LED monitor and charge lamp are OFF, and use a device such as a
tester to ensure that the DC intermediate circuit voltage across main circuit terminals P(+) and N(-) has
dropped to a safe level (+25 VDC or less).
Failure to observe this could result in electric shock.
• Be sure to perform the daily inspection and periodic inspection described in the instruction manual. Lengthy
use of the product without inspection could result in inverter failure and damage, or accident and fire.

depending on the usage conditions.
• It is recommended that parts for periodic replacement be replaced after the standard number of years
indicated in the instruction manual. Lengthy use of the product without replacing parts could result in inverter
failure and damage, or accident and fire.
• Contact outputs [30A/B/C] and [Y5A/C] use relays, and may remain ON or OFF, or in an indefinite state
