Always use this unit properly. Be sure to carefully read the information about the device, the safety information and precautions before using this unit.
  • Page 4 DANGER Devise an emergency stop circuit, interlock circuit, and other similar circuits outside the programmable controller. Disregarding this rule may result in damage to the equipment or cause an accident if the programmable controller fails. Keep it in mind that this hardware unit operates on a high voltage. If the user touches a high-voltage terminal inadvertently during connection or disconnection of this hardware unit or its cable, he or she may suffer from an electric shock.
  • Page 5 REQUIREMENT An electric shock may lead to a death or burn. Noise may cause the system to malfunction. Ground the line ground (LG), frame ground (FG), and shield (SHD) terminals, as described below. • Electrically insulate the mount base from the cubicle. To assure this, do not remove the insulating sheet from the mount base.
  • Page 6 Hitachi Engineering Service Co., Ltd. The malfunctioning part will be replaced or repaired free of charge. If the malfunctioning is shipped, however, the shipment charge and packaging expenses must be paid for by the customer.

    IR.LINK module of the CPU unit to the FG terminal of the CPU unit mount base and the FG terminal of the IR.Station module of the I/O unit to the FG terminal of the I/O unit mount base respectively. This connection puts their grounding potentials at the same level, makes the grounding performance higher, and consequently increases the noise resistance.
  • Page 37 5 CABLING An example of wiring when modules in different I/O units are connected When connecting modules in different I/O units, leave the FG terminal of the IR.Station module open. If connected, the noise resistance will decrease because of different grounding potentials.
