  • Page 3 SAFETY PRECAUTIONS Be sure to read this manual and all other attached documents carefully before installing, operating inspecting or conducting maintenance on this unit. 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 Form emergency shutdown circuits, interlock circuits or the like outside the programmable controller. Failures in the programmable controller may result in damage to the equipment or accidents. Use the I/O current with any I/O module within the maximum allowable limit. Overcurrent flow can cause damage to the parts, resulting in accidents, fires, or failures.
  • Page 5 CAUTION To prevent possible failures, house the programmable controller in a drip-proof enclosure in cases where it is feared to be wetted with water. See Chapter 1 on page 3. Even if the input voltage of the power supply module falls within a specified range, assume it to be in an input power abnormality when it is close to the upper or lower limit of the range, and call upon the power supply facility manager for a checkup.
  • Page 6 CAUTION Dust deposited on the connector can result in degraded contact. Install and wire the equipment immediately upon unpacking. Modules are susceptible to damage. Note the following points when installing or removing modules. • Check that the connectors are free from bent or broken pins and the pins are aligned straight and are free from dust.
