Wire connection
REQUIREMENT
• Connect the wires matching the terminal numbers. Incorrect connection causes a trouble.
• Route the wire through the wire connection port of the indoor unit.
• The low-voltage circuit is provided for the control wire and remote control wire. (Do not connect the high-voltage
circuit.)
• Remove the cover of the electrical control box by removing the mounting screws (3 positions) and push the
hooking section. (The cover of the electrical control box remains hanged to the hinge.)
• Remove the wire cover by removing the mounting screws. (1 position)
• Remove the conduit plate B by removing the mounting screws. (1 position)
• Attach the conduit pipe to the conduit plate A with a lock nut.
• Tighten the screws on the terminal block and secure the wires with cord clamp fitted to the electrical control box.
(Do not apply tension to the connecting section of the terminal block.)
• Use the supplied heat insulation for the sealing of the control wire connecting port. (Otherwise dew condensation
may be caused.)
• Mount the conduit plate B, the wire cover and the cover of the electrical control box ensuring the wires are not
pinched. (Mount the conduit plate B, the wire cover and the cover after the ceiling panel has been wired to the
electrical control box.)

3. Secure the ground wire with the ground screw.
4. Fix the wires with a cord clamp.
Unit: in (mm)
CAUTION
Firmly tighten the screws of the terminal block.
Keep the wire length as shown in figure below when it
is connected to the terminal block.
