The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. [. . . ] (Sold separately) NOTE : The connecting length indicated in the table represents the length from the pull box to the outdoor unit when the indoor units are connected in parallel for power, as shown in the illustration below. A voltage drop of no more than 2% is also assumed. If the connecting length will exceed the length indicated in the table, select the wire thickness in accordance with indoor wiring standards. · Group Control through a Remote Controller Group control of multiple indoor units (8 units) through a single remote controller switch Indoor unit No. 1 AB No. 2 AB No. 3 AB No. 4 AB No. 7 AB No. 8 AB Remote controller (A.

(2) When running power wires and control wires parallel to each other, either run them through separate conduits, or maintain a suitable distance between them. (Current capacity of power wires: 10A or less for 300mm, 50A or less for 500mm) 101 9-5.

(Wire length : 6m) If the length between indoor and FS unit exceeds 5m, connect by using the connection cable kit sold separately (RBC-CBK15FE). 102 9-6. Connection of Power Supply Cable with Control Wire Insert power supply cable and control wire after removing knockout of the piping/wiring panel at front side of the outdoor unit. Knockout for power supply cable Knockout for control wire Piping/wiring panel When insert power supply cable and control wire, protect power supply cable and control wire from edge after removing knockout. Power supply cable 1. Connect the power supply cables and earthing wire to the terminal block of the power supply through a notched section at side of the electric parts box, and fix with a clamp. Bundle the power supply cables using the hole so that they are not out of the notched section of the electric parts box. Control wire 1. Connect the control wire between indoor and outdoor units and the control wire between outdoor units to (U1, U2, U5, U6) terminal section through a hole at side of the electric parts box, and fix with a clamp. Use the control wire with 2-core shield wire (1. 25mm² or more) in order to prevent noise trouble. (Non-polarity) NOTE : 1) Be sure to separate the power supply cables and each control cable. 2) Arrange the power supply cables and each control cable so that they do not contact with the bottom surface of the outdoor unit. 3) A terminal block (U3, U4 terminal blocks) for connecting an optional part "Central remote controller etc. " is provided on the inverter unit, so be careful to miswiring.

C. Electrical Wiring of Flow Selector Unit Wire connections Use the supplied, dedicated wires. REQUIREMENT · Check that power is not supplied to the indoor unit before connecting wires. · For safety, connect wires to the Flow Selector unit first. · Be sure to put wires through the wire connecting ports on the Flow Selector unit and the indoor unit. Connection diagram · Power is supplied from the connected indoor unit. · Connect the attached wires (power supply / control wiring) between the Flow Selector unit and the indoor unit. Connect wires as shown in the below figure.
