Step 6: Connect signal cable TAKE NOTE OF FUSE SPECIFICATIONS <br /> The signal cable enables communication between The air conditioner's circuit board (PCB) is <br /> the indoor and outdoor units. You must first designed with a fuse to provide overcurrent <br /> choose the right cable size before preparing it for protection. The specifications of the fuse <br /> connection. are printed on the circuit board, such as: <br /> Cable Types T3.15A/250VAC, T5A/250VAC, etc. <br /> • Indoor Power Cable (if applicable): 1. Prepare the cable for connection: <br /> HO5VV-F or H05V2V2-F a. Using wire strippers, strip the rubber jacket <br /> • Outdoor Power Cable: HO7RN-F from both ends of signal cable to reveal <br /> • Signal Cable:HO7RN-F about 40mm (1.57in) of the wires inside. <br /> b. Strip the insulation from the ends of the 'o <br /> ea <br /> Minimum Cross-Sectional Area of wires. h <br /> Power and Signal Cables c. Using wire crimper, crimp u-type lugs on O <br /> North America the ends of the wires. <br /> Appliance Amps (A) AWG PAY ATTENTION TO LIVE WIRE <br /> While crimping wires, make sure you clearly <br /> 10 18 distinguish the Live ("L") Wire from other wires. <br /> 13 16 2.
