Power Socket and Inverter System Components

• Power inverter transformer (24V to 230V supply)

• Auxiliary power socket circuits

• Electrical supply connectors

• Control interface wiring

These components provide onboard auxiliary AC power and socket supply through the vehicle electrical system.

---

Power Take-Off Control Components

• PTO control switches

• PTO solenoid activation wiring

• Gearbox PTO interface connections

• PTO enable control circuits

These circuits control mechanical PTO activation and auxiliary hydraulic or mechanical equipment.

---

CAN Bus and Electronic Communication

• Vehicle CAN communication network integration

• Control module interface wiring

• Signal routing between PTO controls and vehicle systems

The PTO and inverter systems communicate with vehicle electronics through the CAN architecture for safe activation and monitoring.

---

Electrical Supply and Fuse Protection

• Central electrical system supply routing

• Fuse-protected auxiliary power circuits

• PTO electrical feed connections

• Ground network references

These protected circuits ensure stable power distribution for both inverter and PTO operation.

---

Wiring Harness Interfaces

• Cab-frame harness connectors

• Frame electrical routing connectors

• Auxiliary interface connectors

• System cut-off connection points

These harness references allow full diagnostic tracing of PTO and auxiliary power electrical systems.
