7.2. Branch box/outdoor wire connection and outdoor power supply cord connection
Z_ Warning:
• Be sure to attach the terminal block covers/panel of the outdoor unit securely. If it is not attached correctly, it could result in a fire or an electric shock due to
dust, water, etc.
• Be sure to connect the power supply cords and the connecting wires for the indoor units, outdoor units, and branch boxes directly to the units (no intermedi-
ate connections).
Intermediate connections can lead to communication errors if water enters the cords or wires and causes insufficient insulation to ground or a poor electrical
contact at the intermediate connection point.
Z_ Caution:
• Be careful not to make mis-wiring.
• Firmly tighten the terminal screws to prevent them from loosening.
• After tightening, pull the wires lightly to confirm that they not move.
If the connecting wire is incorrectly connected to the terminal block, the unit does not operate normally.
