4. Keep transmission wiring at least 50 mm away from power supply wiring. The equipment may malfunction
if subjected to electrical (external) noise.
5. For remote controller wiring, refer to the "INSTALLATION MANUAL OF REMOTE CONTROLLER".
6. Never connect power supply wiring to the terminal board for transmission wiring. A mistake of the
sort could damage the entire system.
7. Use only specified wire and tightly connect wires to terminals. Be careful wires do not place external stress
on terminals. Keep wiring in neat order and so as not to obstruct other equipment such as popping open
the service cover. Make sure the cover closes tight. Incomplete connections could result in overheating,
and in worse case, electric shock or fire.
