English 13• Transmission wiringRemove the EL. COMPO. BOX lid, and connect the transmission wires to the transmission wiring terminals(F1 and F2 on the indoor side and F1 and F2 on the outdoor side). In that case, pull the wires into the equip-ment through the wiring through hole, and bundle and fix the wires securely with the accessory clamp (1).[CAUTIONS]• Do not connect the power supply wiring to terminals F1 and F2 of the transmission wiring terminal block byany means.Otherwise, the entire system may be damaged.CAUTION• Use the accessory clamp (1) when clamping each wire so that the wire will be clamped securely and thatno tension will be imposed on the wiring connection block. When wiring, arrange the wires neatly so that theEL. COMPO. BOX lid will not rise, and attach the cover securely.When attaching the EL. COMPO. BOX lid, pay the utmost attention so that the wires will not be caughtbetween the EL. COMPO. BOX lid.• After the wires are connected, seal the wiring extraction part with putty or heat insulation material (field sup-plied) so that there will be no clearance in order to prevent the intrusion of small animals from the outside.If insects or small animals intrude, short-circuiting may occur in the EL. COMPO. BOX.• Separate the low-voltage wires (transmission wiring) at least 50 mm from high-voltage wires including thepower supply and ground wires outside the equipment so that they will not be wired through the sameplace. Otherwise, the transmission wires will receive electrical noise (external noise), thus resulting in air-conditioner errors and failures.9. TEST OPERATION(1) Check that the EL. COMPO. BOX lid is closed after the installation of the indoor, BEV, and outdoor unitsare all finished.(2) Refer to the installation manuals provided to the indoor and outdoor units for the trial operation of the airconditioner.
