TRANS-AMF three phase connections schematic
1- Connect the unit as shown in the appropriate diagram. Be sure to connect the battery
supply the right way round and battery negative should be grounded.
2- The CAN interface requires that a 120 Ohms terminator is fitted to each end of the
communications link. This termination resistor is fitted internally into the unit. So it is not
required externally. The screen is grounded at one end ONLY.
Screened cable must be used for connecting the Magnetic Pickup, ensuring that the
screen is grounded at one end ONLY.

3-
4- Current transformers secondary should be grounded. The CT of 5VA s recommended.
