8-1 Example of Wiring Entire System
• Use conduit for power supply wiring.
• Make sure the weak electric wiring (i.e. for the remote controller,
between units, etc.) and the power wiring do not pass near each
other, keeping them at least 50 mm apart.
Proximity may cause electrical interference, malfunctions, and
breakage.
• Be sure to connect the power wiring to the power wiring terminal
block and secure it as described in "8-3 Procedure for Incoming
Wiring".
• Do not connect the power supply to the terminal block for the trans-
mission wiring for warning, alarm, operation output, and remote
operation switch. Otherwise the entire system will be damaged.
• Transmission wiring should be secured as described in
"8-4 Procedure for Power Supply Wiring".
• Secure wiring with clamp such as insulation lock ties to avoid con-
tact with piping.
• Shape the wires to prevent the structure such as the control box lid
deforming. And close the cover firmly.
8-2 To Open the Electrical Component Box of the
Outdoor Unit
Do not apply excessive force when opening the electronic component
box cover. Excessive force can deform the cover, resulting in entering
of water to cause equipment failure.
