Refer to 5-5-6 Grounding on page 5-82 for the grounding procedures for the CPU Rack with peripheral
devices and in control panels.
If the ground wire for a Unit with a ground terminal is shared with power equipment, noise will adversely
affect the Units.
You can use OMRON NX-AUX01 DIN Track Insulation Spacers with PFP-50N or PFP-100N DIN Tracks
to isolate the CPU Rack from the control panel.
Installing DIN Track Insulation Spacers and DIN Track
Secure the DIN Track Insulation Spacers to the control panel with screws, and then secure the DIN Track
to the DIN Track Insulation Spacers. The recommended tightening torque for M4 screws is 1.2 N·m.
