(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 (Fig. 4.39).
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.
Erroneous wiring may cause burning of the electric parts.
③. Connect the connection cords firmly to the terminal block. Imperfect installation may cause a fire.
④. Always fasten the outside covering of the connection cord with cord clamps. (If the insulator is not
clamped, electric leakage may occur.)
⑤. Always connect the ground wire.
