1. Remove the black screws and the control box
cover

2. Connecting the power supply cable

Pass the power supply cable through the bush* and connect to the
TB6 terminal block using the round terminals. Connect the ground wire
to the screw and secure tightening the bush. (* Use an item that can
firmly secure the cable such as a PG connector.)

*1. If the installed earth leakage circuit breaker does not have a
function to protect over-current, install a breaker with that function
along the same power line.
*2. A breaker with at least 3.0 mm contact separation in each pole shall
be provided. Use earth leakage breaker (NV).
The breaker shall be provided to ensure disconnection of all active
phase conductors of the supply.

ground value.
Notes
1. Wiring size must comply with the applicable local and national code.
2. Dx-coil unit/outdoor unit connecting cords shall not be lighter than
polychloroprene sheathed flexible cord. (Design 60245 IEC 57)
Dx-coil unit power supply cords shall not be lighter than
polychloroprene sheathed flexible cord. (Design 60227 IEC 53)
3. Install an earth longer than other cables.
CAUTION
• Always separate the power supply cable and transmission
cable by 5 cm or more to prevent malfunctioning of the unit.
• If the length of the stripped Power supply cable is too long, the
conductors may touch and short out.
• Do not tighten screws of terminal block with a torque larger
than 0.5 Nm. It could damage the PCB.
