Step 5: Connect the Shoulder Cable Connectors and Position the Actuators
Seat actuator ID 19 in part 300_14C, connect the XT30 cable connectors to actuators ID 19 and ID 20, and route the single-ended cable through actuator ID 20.
Parts needed
| Part | Count |
|---|---|
| Prepared part 300_14C housing from Step 4 | 1 |
| EC-A4315-P2-36 (ID 19) | 1 |
| EC-A3814-H14-107 (ID 20) | 1 |
| Double ended XT30(2+2) - 100 mm | 1 |
| Single ended XT30(2+2) - 180mm | 1 |
Instructions
Take part from Step 4 and put it flat on a surface, with the inner hollow part facing upward.
Place actuator EC-A4315-P2-36 (ID 19) into the round hollow. The ports on the actuator should be near to the top, and the shaft facing the bottom. The two ports of the actuator should be parallel with the length of .
Connect one connector of the 100 mm double-ended XT30 (2+2) cable to the outward-facing port on actuator ID 19 and the other connector to the outer port on actuator ID 20 .
Connect the XT30 connector of the 180 mm single-ended cable to the center port on actuator ID 20 , then route the cable through the actuator's hollow shaft.
Turn the current assembly upside down.
Align the threaded holes on the shell of actuator EC-A3814-H14-107 (ID 20) with the three hole at the bottom of the long end of Part .
Take 3 – M4x8 Socket Bolts and lightly tighten into the three hole on part to align the part with the actuator.
After the parts are aligned:
- remove each of the 3 – M4x8 socket bolts,
- apply threadlocker,
- then tighten them back to secure Part and the actuator together.
Take 6 – M3x12 Flat Bolts and lightly tighten into the 6 holes on the surfaces of Part to align the part with the actuator.
After the parts are aligned:
- remove each of the 6 – M3x12 flat bolts in a star formation,
- apply threadlocker,
- then tighten them back to secure Part and the actuator together.
Tighten the 3 bolts we have put in place in Step 4 Instruction 3 around the circumference of the part. Don’t over tighten it, it is just meant to secure the actuator in place.
How is this guide?
Step 4: Prepare the Actuator Housing
Install seven M4 square nuts in part 300_14C and retain them with three M4x16 and four M4x25 socket bolts.
Step 6: Close the Shoulder Actuator Housing
Join parts 300_13C and 300_14C around the actuators with the carried socket bolts and secure part 300_13C to actuator ID 20 with three threadlocked M4x8 socket bolts.
