(3) How to fix connection cord and power cord by cord clamp
After passing the connection cord and power cord through the insulation tube, fasten it with the cord
clamp. (Figure 3-2-8)
①. Before starting work, check that power is not being supplied to the indoor unit and outdoor unit.
②. Match the terminal block numbers and connection cord colors with those of the indoor unit side.
③. Erroneous wiring may cause burning of the electric parts.
④. Connect the connection cords firmly to the terminal block. Imperfect installation may cause a fire.
⑤. Always fasten the outside covering of the connection cord with cord clamps. (If the insulator is not
clamped, electric leakage may occur.)
⑥. Always connect the ground wire.
