Handling requirements: Use hand carts and other tools to handle, avoid collision with the front connector of the controller, and prevent damage to the internal PC board.

(2) Electrical connection

Power connection: Connect according to the AC200-230V single-phase specification, with the live wire (L), neutral wire (N), and ground wire connected separately, and the ground wire must be reliably grounded;

Robot cable connection: XM, YM, ROB I/O XY connectors correspond to 1-2 axes, ZM, RM, ROB I/O ZR connectors correspond to 3-4 axes, and must maintain a distance of ≥ 100mm from the power line to avoid confusion of connectors;

Other connections: The MPB programmer needs to be correctly connected to the MPB interface, and if not connected, the MPB terminal needs to be inserted; The absolute battery needs to be connected before the robot cable is connected to avoid origin detection errors.

(3) Wiring specifications

Cable separation: Control lines, communication cables, and robot cables need to be separated from power lines with a spacing of ≥ 100mm, and bundling is prohibited;

Protective measures: The cable should be threaded or fixed to avoid pulling or pulling. When disconnecting the cable, hold the connector instead of the cable itself;

Anti interference: The wiring of electromagnetic contactors, induction motors, and other equipment should be kept away from the controller cables to avoid being laid in the same pipe. If necessary, noise filters and ferrite cores should be installed.
