Set the load measuring jig so that its right end fits to the right end of the PCB clamp. Then, connect the
power cable to any port of the power supply unit of the changing truck.
The jig should be pressed against the rail’s reference side in response to the settings of PCB flow
direction and front/rear reference and set with its end fits to the end of the PCB clamp in the horizontal
direction. Route the wires so that they will not interfere with the head, as shown in the photo
.
