Usage Precautions
Read product specifications and user’s manual thoroughly before usage and use it correctly.
1. Take external safety measures (interlocking, installation of smoke detector, etc.) so that a fail-safe mechanism will
work for the entire system in the case of product failures or errors caused by external factors.
2. Do not disassemble or modify. It may result in failures.
Warranty will be void for failure or breakage occurring from usage with disassembly and modification.
3.
Power source voltage for this device is single phase, 200 to 240V AC (frequency of 50 to 60Hz). Do not use it on
power source voltage and frequency deviating the provision in this manual. It may cause breakage.
4. Customers shall prepare the power cable (AC supply cable) with the diameter appropriate for the maximum input
current (5A).
5. Securely connect the power cable to the terminal block (screw diameter ø4) on the back of the control unit.
6. Connect the ground wire securely.
7. Do not share the power line for this product with motors, machines with induction properties, or devices that
consume large amounts of power.
8. Despite the sufficient resistance to noises superimposed on the power line, it is recommended to use an isolation
transformer and so forth to attenuate noises before feeding the power.
9. Use the supplied cables for the connections among the control unit, power unit, and LED head. Make sure that the
cables are connected securely.
Warranty will be void for failure, breakage or destruction occurring from usage of products other than what’s
designated or recommended by us.
10. When connecting cables to D-Sub37 connector for external I/O, perform soldering accurately to prevent short circuits
between the terminals inside the connector.
11. When connecting an inductive load (motor or relay) to the external I/O, connect a noise absorber (noise killer and so
forth) to the load side.
12. After finishing the connections of the power cable (AC supply cable), securely screw the terminal block cover to
prevent electric shocks.
13. Hold the connector (plug) area when connecting/disconnecting the cables.
14. Wire the cables in such manner to avoid load and stress to the cables and connectors.
15. Place the rubber feet on a horizontal surface.
Do not install in tilted, sidelong, or flipped positions. It may cause breakage due to occurrence of heating.
16. Do not install in a sealed space.
17. Do not block the ventilation hole of the power unit.
18. Please have a margin to installation space, and do not allow the exhaust air from the fan to enter through the air
intake.
19. Check that all the connections are correct before turning on the power.
20. Installation environment:
 Ambient temperature
0 to +35 C
 Ambient humidity
30 to 85%RH (at 25C, no dewing or freezing)
 A place free from dust, oil smoke, conductive dust, corrosive or flammable gas, salt content, and iron dust
 A place free from splashes of water, oil and chemicals
 A place free from sudden temperature changes, vibration and shocks
 A place free from direct sunlight
 A place free from high magnetic field and intense electric field
