Fig. 3-9 shows the installation procedure for the external wiring and piping box. The procedure is the same in RH-
3FH/6FH/12FH/20FH. Remove the No. 2 arm cover B and install this option using the same screw holes. The
installation procedure is shown below.
Turn the controller's power OFF before this operation. Refer to
removing/ installing the cover.
1) Remove the each fixing screws and remove the No. 2 arm cover U and the No. 2 arm cover B.
2) Pull out the air hoses or cables from the opening which removed the No. 2 arm cover B.
3) Fix (or connect) the air hoses and cables to this option box.
Previously adjust the air hose and cables to an appropriate length. Make sure that the wiring and piping lines
avoid the side of the J2 reducer (because gap is narrow, it interfere with the No. 2 arm cover U).

4) Fix the air hoses and cables to the hole inside of this box by using the attached cable tie. (section <e> of
Fig. 3-9)
Note) Be sure to fix the air hoses and cables to prevent the hoses falling out and breaking the cable. Also,
fix carefully so that the air hose and cables may not be pulled too much.
5) Install securely the external wiring and piping box to the screw holes that previously installed the No. 2 arm
cover B by attached screw. (tightening torque: 1.39 to 1.89Nm).
When installing pull it little by little from the No. 2 arm side, making sure that the air hose and cables are not
bent or trapped.
6) Make sure that the wiring and piping lines on the No.2 arm avoid the side of the J2 reducer (because gap is
narrow, it interfere with the No. 2 arm cover U).
Fix the hoses and cables to the hole shown in section <f> of
located left and right.
7) If the cables and the air hoses have excess length, please tie the excess section using cable tie.
8) Install securely the No.2 arm cover U as before with fixing screws (tightening torque: 1.39 to 1.89 Nm).
Note) The installation surface of the clean and the oil-mist specification covers is using sealing material.
In the event that the sealing material has been removed or has been bent or broken to the extent
that it cannot be return to the original form, be sure to replace the sealing material. Please contact
dealer when the sealing material needs to be replaced.
In the case of oil-mist and clean specification models, to ensure the cleanliness level, use liquid gas -
ket and others to seal the outlet on the shaft tip where the air hoses and the cables are pulled out.
The installing of the external wiring and piping box is completed.
