4.1 Wiring
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.
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.
To the instrument with power supply of 24 V, please be sure to supply the power from
SELV circuit.
Ground wiring:
Ground the instrument separately from other equipment. The grounding resistance
should be 100
Ω
or less.
Use grounding wires with a cross section area of 2.0 mm
2
or more.
CAUTION
To prevent electric shock or instrument failure, do not turn on the power until all
the wiring is completed.
