  • Page 33 1 GENERAL INFORMATION (3) The programmable controller must be used within the environmental specification shown in the table below. To make the product run stably for a long period of time, users are advised to use the product at normal temperature (15 to 35°C) and normal humidity (45 to 85%). If it is used in a location subject to high temperature and high humidity or where the temperature greatly fluctuates daily, its useful life will be shortened.
  • Page 34 1 GENERAL INFORMATION (4) Output modules For each output module, connect a fuse to the power supply to the load for protection against load short-circuit. The connected fuse must be one that matches the ratings of the load. If a non-matching fuse is connected, the printed wiring board or casing used may be damaged when the load is short-circuited.
  • Page 35 If a faulty part is found, replace the module containing it. The replacement of a component part other than those mentioned in this manual should be done by Hitachi’s maintenance personnel. (9) Replacement of modules Before replacing a module, be sure to switch off the power supply.
  • Page 36 1 GENERAL INFORMATION (11) Grounding Check the wiring for grounding. • Make sure that the grounding line is not shared with any other piece of equipment. • Make sure that the grounding point is at least 15 meters away from that of the AC panel. Check, also, that no power cable or lead cable (e.g., a motor lead cable) is placed near signal cables, such as a remote I/O cable.
  • Page 37 1 GENERAL INFORMATION NOTICE As the external power supply, select a power supply with overvoltage and overcurrent protection.
