1. Proper earth grounding practices must be observed in this case as any differences in command source and valve ground potential will result in a screen shield ground loop Warning Electromagnetic Compatibility EMC It is necessary to ensure that the unit is wired up as above For effective protection of the user s electrical cabinet the valve subplate or manifold and the cable screens should be connected to efficient ground points The metal 7 pin connector part no 934939 should be used for the integral amplifier In all cases both valve and cable should be kept as far away as possible from any source of electromagnetic radiation such as cables carry ing heavy current relays and certain kinds of portable radio transmitters etc Difficult environments could mean that extra screening may be necessary to avoid the interference It is important to connect the OV lines as shown above The multi core cable should have at least two screens to separate the command signal and monitor output from the power lines The enable line to pin C should be outside the screen which contains the demand signal cables To avoid conducted EMI disturbance in other connected systems ensure to use a dedicated power supply for the KB valves 2 1 7 CANbus Connector Wiring instructions and connector pinning for CANbus M12 5 pin CAN Connector Male 4 in Description CAN Shield Not Connected Power Supply OV CAN High CAN Low Poon 7D M12 5 pin C2.
