Safety Considerations

• Observe all ‘Safety Considerations’ for safe and proper operation to avoid hazards.
• symbol indicates caution due to special circumstances in which hazards may occur.

Warning Failure to follow instructions may result in serious injury or death

1. Fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss. (e.g. nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime / disaster prevention devices, etc.)
   Failure to follow this instruction may result in personal injury, economic loss or fire.
2. Do not use the unit in the place where flammable / explosive / corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact or salinity may be present.
   Failure to follow this instruction may result in explosion or fire.
3. Install on a device panel to use.
   Failure to follow this instruction may result in fire.
4. Do not connect, repair, or inspect the unit while connected to a power source.
   Failure to follow this instruction may result in fire.
5. Check ‘Connections’ before wiring.
   Failure to follow this instruction may result in fire.
6. Do not disassemble or modify the unit.
   Failure to follow this instruction may result in fire

Caution Failure to follow instructions may result in injury or product damage.

1. Use the unit within the rated specifications.
   Failure to follow this instruction may result in fire or product damage.
2. Do not short the load.
   Failure to follow this instruction may result in fire.
3. Do not use the unit near the place where there is the equipment which generates strong magnetic force or high frequency noise and strong alkaline, strong acidic exists.
   Failure to follow this instruction may result in product damage.

Cautions during Use

• Follow instructions in ‘Cautions during Use’. Otherwise, It may cause unexpected accidents.
• 5 VDC⎓, 12 – 24 VDC⎓ power supply should be insulated and limited voltage / current or Class 2, SELV power supply device.
• For using the unit with the equipment which generates noise (switching regulator, inverter, servo motor, etc.), ground the shield wire to the F.G. terminal.
• Ground the shield wire to the F.G. terminal.
• When supplying power with SMPS, ground the F.G. terminal and connect the noise  canceling capacitor between the 0 V and F.G. terminals.
• Wire as short as possible and keep away from high voltage lines or power lines, to prevent inductive noise.
• Check the wire type and response frequency when extending wire because of
  distortion of waveform or residual voltage increment etc. by line resistance or capacity between lines.
• This unit may be used in the following environments.
  • Indoors (in the environment condition rated in ‘Specifications’)
  • Altitude max. 2,000 m
  • Pollution degree 2
  • Installation category II

Cautions during Installation

• Install the unit correctly with the usage environment, location, and the designated specifications.
• Do not load overweight on the shaft.
• Do not put strong impact when insert a coupling into shaft.
  Failure to follow this instruction may result in product damage.
• When fixing the product or coupling with a wrench, tighten under 0.15 N m.
• If the coupling error (parallel misalignment, angular misalignment) between the shaft increases while installation, the life cycle of the coupling and the encoder can be shorten.
• Do not apply tensile strength over 30 N to the cable.

Ordering Information

This is only for reference, the actual prodcut does not support all combinations.
