•
Locations subject to exposure to water, oil, or chemicals
•
Locations subject to shock or vibration
2. Take appropriate and sufficient countermeasures when installing systems in the following
locations:
•
Locations subject to static electricity or other forms of noise
•
Locations subject to strong electromagnetic fields
•
Locations subject to possible exposure to radioactivity
•
Locations close to power supplies
• Application Precautions
1. When unpacking the Units, check carefully for any external scratches or other damage.
Also, shake the Units gently and check for any abnormal sound.
2. The mounting panel must be between 1.6 and 4.8 mm thick. Tighten the Mounting
Brackets evenly to a torque of between 0.5 and 0.6 N ⋅ m to maintain water and dust
resistance. Make sure the panel is not dirty or warped and that it is strong enough to hold
the Units.
3. Do not let metal particles enter the Units when preparing the panel.
4. If conformance to EC Directives (Low Voltage Directive) is required, use reinforced
insulation for the power supplies.
5. Do not connect an AC power supply to the power terminals.
6. Use a DC power supply with minimal fluctuation voltage.
Rated power supply voltage: 24 VDC
(Allowable range: 20.4 to 27.6 VDC)
Capacity: 25 W min. (NS5: 15 W min.)
7. Do not perform a dielectric voltage test.
8. Use a twisted-pair cable with a cross-sectional area of at least 2 mm
power terminals and always use M3.5 crimp terminals. Tighten the terminal screws to a
torque of 0.8 N ⋅ m. Make sure the screws are properly tightened.
9. Ground the Unit correctly to prevent operational errors caused by noise.
10. Do not touch the surface of the circuit board or the components mounted on it with your
bare hands. Discharge any static electricity from your body before handling the board.
11. Confirm that the current capacity of the connected device is 250 mA or less before using
the 5-V power supply from pin 6 of the serial port A, B connectors. The 5-V output of the
PT is 250 mA max. at 5 V ± 5%.
12. Turn OFF the power supply before connecting or disconnecting cables.
13. Always tighten the connector screws after connecting communications cables.
14. The maximum tensile load for cables is 30 N. Do not apply loads greater than this.
15. Confirm the safety of the system before turning ON or OFF the power supply or before
pressing the reset button.
16. The whole system may stop depending on how the power supply is turned ON or OFF.
Turn ON or OFF the power supply according to the specified procedure.
17. Start actual system application only after sufficiently checking screen data. macros, and
the operation of the program in the PC (host).
18. Always reset the power supply after changing switch settings.
19. After changing the settings of the DIP switch, always turn the power supply OFF and ON
or reset the PT.
20. Do not perform the following operations while the Memory Card is being accessed:
•
Turning OFF the power supply to the PT
•
Pressing the PT's reset switch
•
Removing the Memory Card
•
Always following the specified procedure when removing the Memory Card
21. Do not press the touch switch with a force greater than 30 N.
22. Confirm the safety of the system before pressing touch switches.
