7.3 Device CAN communication connection and address settings
As shown in 7.2.1, each set of AIM-M300/SG, AIL150 serve as a subsystem formally, while in practical
application, the CAN communication connection and address settings should be conducted in the
following ways.
1) Connect with shielded twisted pair according to the following figure. Note each of the two
terminals of the CAN bus wire should be added a matched resistance of 120Ω.

2) When setting CAN address, it is only needed to set the
CAN address of AIM-M300 series IMD
to any value between 1 to 110 after the 4 meters are on a unified power, then save the value and
the CAN address of AIL150 can be simultaneously set the same with address of AIM-M300(or AIM-M300/SG).
In the confirmation of saving the AIM-M300(or AIM-M300/SG) CAN address, note whether the
communication lights of AIL150 are flashing several times. If flashing, the address settings are
normal, otherwise, it is needed to check the communication wiring and confirm that the wiring is
intact and then reset.
8 Typical applications
8.1 Applications of insulation monitoring and fault locating six pieces of products in ICU/CCU
Note: The grounding bar in the isolated power supply cabinet should be connected reliably with the
equipotential terminals in the field.
