Wiring for Power Supply and Grounding
Power supply wiring
WARNING
Be sure to turn OFF the power supply before wiring. Use a tester or similar device to ensure that no power is being
supplied to a cable to be connected.
Install the power cable keeping a distance of more than 1 cm from other signal wires.
The power cable is required to meet the IEC standards concerned or the requirements of the area in which the instrument
is being installed.
For the power cable, the temperature rating is 60 °C or more.
For products with optional code /FM or /CSA:
• When devices are installed in a hazardous area in Class I, Division 2, wire a power supply cable from a non-hazardous
area by explosion-proof wiring (including metal conduit wiring).
• In case of option code /FM, install devices according to NEC (National Electrical Code: ANSI/NFPA-70).
In case of option code /CSA, all wiring shall comply with Canadian Electrical Code Part I and local electrical codes.
Ground wiring
WARNING
The YS1000 should always be grounded to protect the operator and maintenance personnel from electric shock and to
prevent the effects of external noise. Ground wiring should be grounded to Ground (minimum resistance).
For the ground cable, the temperature rating is 60 °C or more.
WARNING
After completion of power cable wiring and ground wiring, always install the terminal cover to the instrument.
Note
If there are multiple YS1000s on the same panel and individual grounding cannot be provided, determine the location of a
grounding bus lead-in at one location and use and connect grounding cables of 2 mm
2
or more from each YS1000 to the
grounding bus.
