* 3: Damage to property refers to extended damage related to houses, household goods, livestock, or pets, etc.
DANGER
• Set the circuit-breaker to "OFF" before starting work
Failing to do so may result in a high-voltage electric shock, leading to death or injury.
• Do not turn on the circuit-breaker when the cover is removed
Doing so may result in a high-voltage electric shock leading to death or injury.
WARNING
• Check that the earth wire (*) is connected to the unit earth terminal before
beginning troubleshooting and repair work
If the earth wire is not connected, there is the risk of electric shock in the event of an electric
leakage occurring.
• Do not modify the product
Also, do not disassemble or modify the parts.
Doing so may cause fire, electric shock, or injury.
• Only qualified engineers should be allowed on a troubleshooting or repair work
site. Children and all other third parties must be kept away
There is a risk of injury from tools or disassembled parts.
Inform the customer that children and other third parties must be kept away from the work site.
• After connecting a crimp terminal to a cut lead wire, place the closed-end facing
up and clean it
If connections are not properly processed, electrical leakage, ignition or other accident could
occur on the customer’s premises.
• After repairs are complete, be sure to reassemble the disassembled parts and
connect and route the wires to restore the equipment to its original state. Make
sure internal wires are not trapped in the cabinets, panels, or other parts
An assembly or wire connection problem may result in a short circuit, ignition or other accident on
the customer's premises.

• If you have to inspect a circuit that is energized, for example, take precautions
such as wearing rubber gloves to avoid direct contact with a live part
Touching a live part may result in an electric shock.
• Check that there are no abnormalities after completing the repair work
Failure to perform this check may result in fire, electric shock, or injury.
Turn off the earth leakage breaker before performing an inspection.
• After completing the repair work, perform a test run and check that there are no
abnormalities such as smoke or unusual noise
Failure to perform this check may result in fire or electric shock.
Perform a test run after installing the front panel and cabinets.
• Installation and reinstallation work should be performed by your vendor or a
qualified electrician
Attempting to carry out installation work on your own, and doing so incorrectly, may result in
