The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
  • Page 8 Safety Precautions Safety Precautions CAUTION Minor injury due to electric shock may occasionally occur. Do not touch the terminals while power is being supplied. Electric shock, fire, or malfunction may occasionally occur. Do not allow metal objects, conductors, cuttings from installation work, or moisture to enter the Digital Controller or a Setup Tool port.
  • Page 9 Safety Precautions CAUTION Loose screws may occasionally result in fire. Tighten the terminal screws to the specified torque of 0.43 to 0.58 N·m. Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable, unexpected operation may occasionally result in property damage or accidents.

Not doing so may occasionally result in unex- pected events. Do not handle the Digital Controller in ways that exceed the ratings. •...
  • Page 11 Precautions for Safe Use • Design the system (e.g., control panel) considering the 2 seconds of delay in setting the Digital Controller’s output after the power supply is turned ON. • The output will turn OFF when you move to the Initial Setting Level. Take this into consideration when performing control.
  • Page 12 When waterproofing is required, insert the Waterproof Packing on the backside of the front panel. Keep the Port Cover on the front-panel Setup Tool port of the E5EC-T/E5AC-T securely closed. The degree of protection when the Waterproof Packing is used is IP66. To maintain an IP66 degree of...

  • Page 13: Precautions For Operation

    Precautions for Operation Precautions for Operation • It takes approximately two seconds for the outputs to turn ON from after the power supply is turned ON. Design the system (e.g., control panel) to allow for this delay. • The Digital Controller requires 30 minutes to warm up after the power supply is turned ON. Always turn ON the power supply at least 30 minutes before starting actual control operations.
  • Page 14 Preparations for Use Preparations for Use Be sure to thoroughly read and understand the manual provided with the product, and check the follow- ing points. Timing Check point Details Purchasing Product After purchase, check that the product and packaging are not dented or the product appearance otherwise damaged.
