Precautions for Safe Use
Observe the following precautions when using the NSA-series Industrial PC.
1. When you unpack the NSA-series Industrial PC, check carefully for any
external scratches or other damage. Also, shake the NSA-series Industrial PC
gently and check for any abnormal sounds.
2. The NSA-series Industrial PC must be installed in a control panel.
3. The panel must be a type 1 enclosure.
4. The mounting panel must be between 1.6 and 4.0 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 NSA-series Industrial PC.
5. Do not let metal particles enter the NSA-series Industrial PC when preparing
the panel.
6. Use the NSA-series Industrial PC in an environment with a pollution degree of
2 or better.
7. Do not connect an AC power supply to the DC power supply terminals.
8. Use a DC power supply with reinforced or double insulation and minimal
voltage fluctuation. The power supply must be capable of maintaining a stable
output for momentary power interruptions in the input of up to 10 ms.
· Rated power supply voltage: 24 VDC (Allowable range: 20.4 to 27.6 VDC)
· Capacity: 80 W min.
9. Do not perform a dielectric voltage test.
10. Connect the power supply to the power supply terminal block using a
twisted-pair cable with stranded copper wire between AWG16 and AWG12 with
a rated temperature of 75°C. Tighten the terminal screws to a torque of 0.5 to
0.6 N·m (5 to 7 lb·in). Be sure the screws are properly tightened.
11. Ground the NSA-series Industrial PC properly to prevent malfunction due to
noise.
12. Do not touch the components mounted on the boards with your bare hands.
Discharge static electricity from your body in advance.
13. Make sure that the power supply is OFF before you connect or disconnect any
cable.
14. Always hold the power supply connector by the housing when connecting or
disconnecting it. If you pull on the cable when connecting or disconnecting the
connector, heating, fire, or electric shock may occur.
15. Always tighten the screws on the connector after connecting the
communications cable. Tighten the screws for COM port 1 and 2 to a torque of
0.23 N·m.
16. The maximum tensile load for cables is 30 N. Do not apply loads greater than
this.
17. Confirm the safety of the system before turning ON or OFF the power supply.
