Warning
Caution
* After installation is completed, perform a test run to check for operating trouble. Explain operating procedures to the customer following the
central control device Operation Manual and then request the customer to store this Instructions for the Electrical Installer together with the
central control device Operation Manual.
Be sure to arrange installation by the dealer where the system was purchased or by a professional installer. Electric shock or fire may result
if an inexperienced person performs any installation or wiring procedures incorrectly.
Be sure that this unit is securely installed in accordance with this Instructions for the Electrical Installer. Electric shock or fire may result if
any installation or wiring procedures are incorrectly performed.
Only a qualified electrician should attempt to connect this system, in accordance with the instructions in this manual. Insufficient electrical
circuit capacity or incorrect installation may cause electric shock and fire.
Use the specified cables for the electrical connections, and connect the cables securely. Run and fasten the cables securely so that
external forces or pressure placed on the cables will not be transmitted to the connection terminals. Overheating or fire may result if
connections or attachments are not secure.
Depending on the installation conditions and location, an earth leakage breaker may be required. If an earth-leakage breaker is not
installed, there is a danger of electric shock or fire.
The installation location requires the use of a circuit breaker. Failure to use a circuit breaker may result in electric shock or fire.
Circuit breaker must be incorporated in the fixed wiring in accordance with the wiring regulations. The circuit breaker must be an approved
10-16 A, having a contact separation in all poles.
Ground yourself to discharge static electricity before performing any wiring.
