Precautions for Correct Use
To ensure this NX Unit is kept in the best operating condition, observe the following points
when wiring to avoid the effects of the noise.
• Use a shield wire (2 conductors, twisted wire) or a shield wire (3 conductors) as the input
connection line for each output. Connect the shield according to the specifications of the
input device.
• Wire the output connection lines and power lines (e.g., AC power supply lines or power
lines) separately. Do not place such lines in the same duct.
• Insert a noise filter into the power supply input section if noise comes from power supply
lines when using the same power supply to power an electrical welder or an electric dis-
charge machine, or there is a high-frequency source nearby.
