The 24-VDC power supply is not provided by Yaskawa. Use a 24-VDC power supply with double insulation or
reinforced insulation.

Always use line receivers to receive the output signals.
Note: 1. You can use parameters to change the functions allocated to the /SI0, /SI3, P-OT, N-OT, /Probe1, /Probe2,
2. If you use a 24-V brake, install a separate power supply for the 24-VDC power supply from other power
