Be sure to use the standard attachments or the genuine parts.
Use of other parts may cause malfunction, electrical shock, or fire.
• Disconnect power to the connected equipment before
starting installation.
Failure to do so may cause malfunction, electrical shock, or fire.
• An earth leakage circuit breaker should be installed.
If the breaker is not installed, electrical shock may occur.
•
Do not install the set in a location where there is danger of
exposure to inflammable gas.
Gas accumulated around the unit at the worst may cause fire.
• To prevent damage due to electrostatic discharge, touch

sash, etc.) to discharge static electricity from your body
before touching this kit.
Static electricity can damage this kit.
• Lay this cable separately from other power cables to avoid
external electrical noises.
•
After installation is complete, test the operation of the PCB set to
check for problems, and explain how to use the set to the end-user.
Failure to follow WARNING is very likely to result in
