For effective protection the user 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 sources of electromagnetic radiation such as cables carrying 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 0V lines as shown above. The multi-core cable should have at least two screens to separate the demand 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. 18 Application Data Fluid Cleanliness Installation Service Information The proportional valves in this catalog can The products from this range are preset Proper fluid condition is essential for be mounted in any attitude, but it may be at the factory for optimum performance; long and satisfactory life of hydraulic necessary in certain demanding disassembling critical items would components and systems.
