3.4.6 Termination Resistor Installation

When a single cabinet is used, the termination resistance must be connected to the CAN2

communication interface of BAT4. When there are two / three / four cabinets in parallel, the
termination resistance must be connected to the CAN2 communication interface of BAT4 in the last
parallel cabinet.

Picture 3-14Termination resistance installation

3.4.7 Cabinet door grounding

The ground wire has been installed on the ground point of the left and right side doors. As

shown in the figure, use screws to fix the yellow wire (labeled BAT / GND) to the frame ground
point, and use a screwdriver to tighten the screws.
