polarity should be installed correctly, otherwise it will cause damage to the equipment.

The maximum allowable voltage is DC 30V and maximum allowable current is DC20mA for open collector output circuit.
2.2.7 Noise and High Harmonic Countermeasures
Here explains the countermeasures against noise and high harmonics.
This servo unit has a built-in microprocessor. Therefore, it may be subject to noise interference from its peripheral devices. To prevent
mutual noise interference between the servo unit and its peripheral devices, take the following countermeasures to prevent noise interference as
necessary.
⚫
Be sure to locate the input command device and noise filter as close as possible to the servo unit.
⚫
Be sure to connect surge suppressors to the coils of relays, solenoids, and solenoid contactors.
⚫
Do not use the same bushing for the main circuit cable and the input/output signals/encoder cable, and do not tie them together. When wiring,
keep the main circuit cable and the input/output signal cable/encoder cable away apart above 30 cm.
⚫
Do not use the same power source with a welding machine or EDM machine, etc. Even if the power supply is not the same, connect a noise
filter to the input side of the main circuit power cable and control power cable when there is a high frequency generator nearby.
