FMCQ50~125A7VEBAir conditioning system4PW47629-1Installation and operation manual6- Confirm the drain operation looking at the drain socket.- After checking the drainage flow, turn off the power,remove the control box lid and disconnect the powersupply from the terminal again.- Reattach the control box lid.ELECTRIC WIRING WORKGeneral instructions■ All field supplied parts and materials and electric works mustconform to local codes.■ Use copper wire only.■ Follow the "Wiring diagram" attached to the unit body to wire theoutdoor unit, indoor units and the remote controller. For detailson hooking up the remote controller, refer to the "Installationmanual of the remote controller".■ All wiring must be performed by an authorized electrician.■ Attach the earth leakage circuit breaker and fuse to the powersupply line.■ A main switch or other means for disconnection, having acontact separation in all poles, must be incorporated in the fixedwiring in accordance with relevant local and national legislation.Note that the operation will restart automatically if the mainpower supply is turned off and then turned back on again.■ This system consists of multiple indoor units. Mark each indoorunit as unit A, unit B..., and be sure the terminal block wiring tothe outdoor unit is matching properly. If wiring and pipingbetween the outdoor unit and an indoor unit are mismatched,the system may cause a malfunction.■ Be sure to ground the air conditioner.■ Do not connect the ground wire to:- gas pipes: might cause explosions or fire if gas leaks.- telephone ground wires or lightning rods: might causeabnormally high electric potential in the ground duringlightning storms.- plumbing pipes: no grounding effect if hard vinyl piping isused.Electrical characteristicsMCA: Min. circuit Amps (A)MFA: Max.

While doing this, pull thewires inside through the hole in the casing and clamp the wiresalong with other wires using a clamp as indicated in the figure.■ Unit transmission wiring and remote controller wiringRemove the control box lid (1) and pull the wires inside throughthe hole in the casing and connect to the terminal block for unittransmission wiring (F1, F2) and remote controller wiring(P1, P2). Securely fix the wiring using a clamp as indicated inthe figure.■ After connectionAttach the small sealing (supplied with the unit) around thecables to prevent infiltrating of water from the outside into theunit. If two or more cables are used, divide the small sealing intothe required number of pieces and wrap them around all thecables.■ Attach the control box lid.Precautions1 Observe the notes mentioned below when wiring to the powersupply terminal block.- Use a round crimp-style terminal for insulation sleeve forconnection to the terminal block for wiring the units. Whennone are available, follow the instructions below.- Do not connect wires of different gauge to the same powersupply terminal. (Looseness in the connection may causeoverheating.)- When clamping wiring, use the clamps (delivered with theunit) to prevent outside pressure being exerted on the wiringconnections. Tie up firmly. When doing the wiring, make surethe wiring is neat and does not cause the control box to stickup. Close the cover firmly.Inter unit wiring terminal block (3)Model Hz Volts Voltage rangeFMCQ50~125 50 220-240 min. 198-max. 264power supply Fan motorModel MCA MFA KW FLAFMCQ50 0.6 16 A 0.056 0.5FMCQ60 0.9 16 A 0.056 0.7FMCQ71 0.9 16 A 0.120 0.7FMCQ100 1.4 16 A 0.120 1.1FMCQ125 1.9 16 A 0.120 1.5NOTE For details, refer to "Electrical data".LN Power supply wiringModel Field fuses Wire SizeFMCQ50~125 16 A H05VV-U3G Local codesTransmission wiringModel Wire SizeFMCQ50~125 Sheathed wire (2) 0.75-1.25 mm2NOTE ■ For details, refer to "Wiring example" on page 7.■ Allowable length of transmission wiring betweenindoor and outdoor units, and between the indoorunit and the remote controller is as follows:• Outdoor unit - indoor unit: max. 1000 m(total wiring length: 2000 m)• Indoor unit - remote controller: max 500 m1 2 31 Round crimp-style terminal2 Attach insulation sleeve3 Wiring
