Grounding for Noise Countermeasures
The ELECYLINDER has a built-in controller circuit board.
The controller frame grounding line is connected to the ELECYLINDER body and through to ground via the ELECYLINDER mounting surface.

The ELECYLINDER has a built-in controller circuit board.
Make sure to perform grounding as shown in the figure below in order to prevent electric shock and electrostatic charge, to improve noise durability performance and to control unexpected radiation.

Notes on Wiring Method
The grounding should be Class D grounding (former Class 3 grounding: Grounding resistor 100Ω or less).
- Have the power supply wires twisted.
- In order to reduce influence to each other, the I/O cable, communication cable and power supply cable should be allocated separate from each other.
Noise Sources and Noise Prevention
For the same power supply circuit and power supply device in the same device, take measures against noise.
Countermeasure examples for noise sources are shown below.
Countermeasure examples for noise sources are shown below.
- AC solenoid valve / magnetic switch / relay
[Measure] Install an anti-noise device in parallel with the coil.
- DC solenoid valve / magnetic switch / relay
[Measure] Install a diode in parallel with the coil or use the diode built-in type.
