- Page 7 Caution ■Provide grounding to assure the noise resistance of the Serial System. Individual grounding should be provided close to the product with a short cable. ■NOTE ○Follow the instructions given below when designing, selecting and handling the product. The instructions on design and selection (installation, wiring, environment, adjustment, operation, maintenance, etc.) described below must also be followed.
- Page 8 Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess voltage or current being applied to the SI Unit, causing damage. Take appropriate measures against noise, such as using a noise filter, when the fieldbus system is incorporated into equipment.
- Page 9 Otherwise safety is not assured due to an unexpected malfunction or incorrect operation. Do not use solvents such as benzene, thinner etc. to clean the SI unit. They could damage the surface of the body and erase the markings on the body.
- Page 10 Fieldbus System/ Industrial IoT Cybersecurity In recent years, factories have introduced industrial IoT, building up complex networks of production machines. These systems maybe subject to a new threat, cyberattack. To protect the industrial IoT from cyberattacks, it is important to take multiple measures (multi-layer protection) for IoT devices, networks and clouds.

Page 18: Wiring
Fig. 3-2 Top view of the valve manifold (SY3000 series) 3.2. Wiring Caution To prevent damage, all supply voltages to the SI Unit must be turned off (i.e. de-energized) before the modules are installed or removed. Connect the functional earth cable, the PROFINET cables and the power cable. - Page 19 3.2.1. PROFINET/Power connection The SI Unit has two PROFINET communication connectors. If only one connector is used, cover the unused connector with a seal cap so that the protection rating of IP67 is maintained. Caution Seal caps must be fitted to all unused bus connector ports to ensure an IP67 rating.
- Page 20 Note: When the autonegotiation function is disabled, you must use the correct network cable, refer to Fig 3-6, 3-7, 3-8. Auto crossover function is not available when the autonegotiation function is disabled. Auto crossover function shall be capable of switching over their twisted pair ports automatically between MDI and MDI-X pin assignment.
- Page 21 The SI Unit must be connected to FE (Functional Earth) to divert electromagnetic interference. Connect a grounding cable from the FE terminal screw on the SI Unit to the nearest functional earth point. The grounding cable should be as thick and short as reasonably possible.
