NOISE – ELECTRICAL CONNECTIONS AND SHIELDING
To reduce noise, separate all power and output wires from those of the input and CAN. Shielded
wires will protect against injected noise. Shield wires should be connected at the power or input
source, or at the output load.
The CAN shield can be connected at the controller using the CAN Shield pin provide on the
connector. However the other end should not be connected in this case.
All wires used must be 16 or 18 AWG.
GROUNDING
Protective Earth (PE) must be connected to the module’s grounding lug to reduce the risk of
electric shock. The conductor providing the connection must have a ring lug and wire larger than or
equal to 4 mm
2
(12 AWG). The ring lug should be placed between the nut and a star washer.
All chassis grounding should go to a single ground point designated for the machine and all related
equipment. Axiomatic recommends that the ground strap that provides a low impedance path for
EMI should be a ½ inch wide, flat, hollow braid, no more than 12 inches long .
FUSING
When installing the unit, an external 3A, 32Vdc fuse is required.
CAN WIRING
The CAN port is electrically isolated from all other circuits. The isolation is SELV rated with respect
to product safety requirements. Refer to the CAN specification for more information.
Use CAN compatible cabling, recommended for on engine use.
Shielded CAN cable is required. The module provides the CAN port shield connection ac coupled
to chassis ground. The chassis ground stud located on the mounting foot must be tied directly to
Earth Ground.
