4. WIRING
4.1 Wiring of H-PCP-G Module
Power supply wiring:
z Use power supply as specified in power supply rated voltage range.
z Power supply wiring must be twisted and have a low voltage drop.
z Provide separate power supply for this instrument independent of other input/output
circuits, motors, equipment and operating circuits.
z 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.
z For an instrument with 24 V power supply input, supply power from “SELV” circuit
defined as IEC 60950-1.
z A suitable power supply should be considered in the end-use equipment.
The power supply must be in compliance with a limited-energy circuits (maximum
available current of 8 A).
Input/output wiring:
z Use independent ducts for the input/output wires and power circuits inside and outside
the panel.
z If input/output wires have to be placed in the same duct as the power circuits, use
shielded wires. Ground the shield to reject any noise generated by the floating
capacitance between the cores and shield or by a grounding potential.
Grounding wiring:
z Use grounding wires with a cross section of 2.0 mm
2
or more.
FAIL output wiring:
Configure the external relay circuit of the FAIL output so that instrument failure does not
affect the entire system. Configuration of an emergency stop circuit is also required to
protect the system.
CAUTION
To prevent electric shock or instrument failure, do not turn on the power until all
wiring is completed. Make sure that the wiring is correct before applying power
to the instrument.
