Picking power line and transmission line
•
Be sure to let the power line and the transmission line pass through a conduit hole.
•
Pick the power line from the upper hole on the left side plate, from the front position of the main unit (through the conduit hole of the wiring
mounting plate - optional parts) or from a knock out hole to be made in the unit’s bottom plate.

2. RXEP8,10 (sub unit)
3. Through -slot cover
4. Cut out the diagonal line area
5. Power cord
6. Separate
7. Branch wiring between indoor and outdoor units.
8. Branch wiring between outdoor units (high voltage)
9. Branch wiring between outdoor units (low voltage)
10. cable (low voltage)
11. liquid line
12. insulation material

•
If you pick the power line from the front position of the unit, proceed as follows and refer to figure 28:
•
Remove the lower frontplate (1), punch a hole in the knock hole and cut the hole (2) all the way to the slit.
•
Attach the 3 sealing pads (optional parts) (3) on the wiring mounting plate (optional parts) (4) corresponding to the over-lapped area of the front
plate.
•
Install the wiring mounting plate to the front side of the side plate with the 2 delivered screws.
•
Pick the transmission line from the middle positioned conduit hole on the left side plate, or from the front position of the main unit (after binding
it to the piping with finishing tape as in figure 29).
1. liquid side pipe
2. gas side pipe
3. pipe heat insulation
4. transmission line
5. finishing tape
NOTE
Be sure to keep the power line and transmission line apart from each other.
Be careful about polarity of the transmission line.
Make sure that the transmission line is clamped as shown in the figure in chapter “Field line connection”.
Check that wiring lines do not make contact with refrigerant piping.
Firmly close the lid and arrange the electrical wires so as to prevent the lid or other parts from coming loose.
When you don’t use a wire conduit, be sure to protect the wires with vinyl tubes etc, to prevent the edge of the knock-out hole from cutting the
wires.
