CAN and RS232 Shielding
•
For the CAN connection on the user interface connector, use a high quality, insulated, shielded, twisted
pair cable (refer Danfoss Power Solutions p/n 14020-019, page 27. Do not allow the shield to touch the
motor or controller housing. (See
Section 6
for information on placement of termination resistors).
•
When using CAN, ensure that you have a ground connection on the user interface connector CAN_COM
to the same source as the CAN signal, using the CAN shield or a separate ground connection. The CAN
circuits within the Danfoss Power Solutions controller are isolated from the 24 V system as well as the
high voltage. Providing the ground connection from CAN_COM to a ground of your upper level
controller allows the CAN signal reference to be the upper level controller ground.
•
For the RS232 cable, you can also use the same type of shielded, twisted, pair cable used on the CAN,
and use the shield for the RS232_COM pin connection.
•
Ensure that the MCU has a solid connection from the enclosure to the vehicle chassis. This can be done
with a braided strap or by directly mounting the MCU to the chassis. This ensures a low impedance
conduction path of the EMI noise.
