5.1 Wiring Precautions
Power supply wiring
•
Use power supply as specified in power supply voltage range.
•
Power supply wiring must be twisted and have a low voltage drop.
•
Provide separate power supply for this instrument independent of other input/output circuits, motors,
equipment and operating circuits.
•
To the instrument with power supply of 24V, please be sure to supply the power from SELV circuit
•
If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise
filter.
−
Shorten the distance between the twisted power supply wire pitches to achieve the most effective
noise reduction.
−
Always install the noise filter on a grounded panel.
−
Minimize the wiring distance between the noise filter output and the instrument power supply
terminals to achieve the most effective noise reduction.
−
Do not connect fuses or switches to the noise filter output wiring as this will reduce the
effectiveness of the noise filter.
−
Take into consideration the instrument power supply voltage and filter frequency characteristics
when selecting the most effective noise filter.
