Notice for encoder installation

1. Please read the encoder specification carefully before installation

2. Encoder is belong to precision instrument, so we should avoid shock or vibration to protect interior parts.

3. The power supply voltage must be holded within specified range, or encoder could be destroyed.

4. Notice coaxially requirements when you install the power shaft, please use flexible coupling and do not press encoder forcibly.

5. Shielding cable of encoder must be connected to avoid electromagnetism interference of alternating current, cables of encoder should be layout individually.

6. Wiring diagram connection should be strictly follow the specified color in catalogue, or encoder interior circuit may be destroyed

7. Encoder should be apart from powerful magnetic field, dust, oil, water, higher (lower) temperature and caustic or flammable material during working.

8. The encoder cable signal can’t be drew or bent forcibly.
