Protective ground
Always perform protective grounding.
Precautions
Use a protective grounding conductor to prevent dangerous voltage on ground when an error occurs. Improper grounding can
lead to serious accidents.
DIN rail
Follow the items below when using a DIN rail.
• Mount a DIN rail with screws and rivets compatible with low-impedance attachments even at a high frequency over the
widest possible area.
• Perform grounding properly.
• Use the corrosive-resistant DIN rail.
• Remove insulation coating, alumite treatment, or insulated metal parts from connections.
• Protect connections from corrosion. (Only grease that is not easily corroded can be used.)
Wiring to external devices
To prevent looped wiring from functioning as an antenna, bundle all the lines connected to the specific external device.
