Measures To Comply With The Low Voltage Directive - Mitsubishi Electric MELSEC SW1DNC-CCIEF-B User Manual

Noise filter (power supply line filter)
Noise filter is effective for reducing conducted noise in the 10MHz or less frequency. (Use of a noise filter can suppress noise.)
The installation precautions are described below.
• Do not bundle the cables on the input side and output side of the noise filter. If bundled, the output side noise will be
induced into the filtered cable on the input side.

(device side)
Noise will be induced when the input
and output cables are bundled.
• Ground the ground terminal of the noise filter to the ground point of the control panel with the shortest ground wire possible
(approximately 10cm).

Measures to comply with the Low Voltage Directive

The CC-Link IE Field Network board is out of the requirement for conformance to the Low Voltage Directive, since it does not
use the power supply in the range of 50 to 1000 VAC and 75 to 1500 VDC.
