Safety Considerations
Observe all ‘Safety Considerations’ for safe and proper operation to avoid
hazards.
Warning Failure to follow instructions may result in serious injury or
death.
- Fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss.(e.g. nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime / disaster prevention devices, etc.) Failure to follow this instruction may result in personal injury, economic loss or fire. Do not use the unit in the place where flammable / explosive / corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact or salinity may be present.
- Failure to follow this instruction may result in explosion or fire.
- Install on the device panel, and ground to the bolt for grounding separately. Failure to follow this instruction may result in fire or electric shock.
- Do not connect, repair, or inspect the unit while connected to a power source. Failure to follow this instruction may result in fire or electric shock.
- Check ‘Connections’ before wiring. Failure to follow this instruction may result in fire.
- Do not disassemble or modify the unit. Failure to follow this instruction may result in fire or electric shock.
Caution Failure to follow instructions may result in injury or product damage.
- Use the unit within the rated specifications. Failure to follow this instruction may result in fire or product damage.
- Use a dry cloth to clean the unit, and do not use water or organic solvent. Failure to follow this instruction may result in fire or electric shock.
- Keep the product away from metal chip, dust, and wire residue which flow into the unit. Failure to follow this instruction may result in fire or product damage.
- Since leakage current still flows right after turning off the power or in the output OFF status, do not touch the load terminal. Failure to follow this instruction may result in electric shock.
Cautions during Use
Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
- Use the product, after 3 sec of supplying power. Before use, set the mode and function according to the specification. Especially, be cautious that the product does not operate when OUT ADJ. is set to 0%. Since changing the mode / parameter during operation may result in malfunction, set the mode and function after disconnecting load output.
- Re-supply the power to the unit after the unit is discharged completely. Failure to follow this instruction may result in malfunction.
- To ensure the reliability of the product, install the product on the panel or metal surface vertically to the ground. Install the unit in the well ventilated place.
- While supplying power to the load or right after turning off the power of the load, do not touch the body and heat sink. Failure to follow this instruction may result in a burn due to the high temperature.
- Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.
- Do not wire to terminals which are not used.
- Since inter element can be damaged when using with coil load, inductive load, etc.,
- Do not use near the equipment which generates strong magnetic force or high frequency noise.
- This unit may be used in the following environments.
- Indoors (in the environment condition rated in ‘Specifications’)
- Altitude max. 2,000 m
- Pollution degree 2
- Installation category III

operation
| Feedback control
- SCR error alarm Even though output is 0%, if the current of 10% or more of the rated load current flows for over 3 sec continuously, SCR error alarm occurs.
- Over current alarm This function protects the load from over current. If the current flows over the P2-7 over current alarm value and P2-8 over current alarm delay time, over current alarm occurs.
- Heatsink over heat alarm When the temperature of a heatsink is over 85 ℃, heatsink over heat alarm occurs.
- Over voltage alarm This function protects the load from over voltage. If the current flows over the P2-9 over voltage alarm value and P2-10 over voltage alarm delay time, over voltage alarm occurs.
- Fuse break alarm When breaking fuse, not suppling load power, breaking load (single load), fuse brake alarm occurs. In the case of normal control model, real-time fuse break alarm is not available during output, and fuse break alarm operates at 0% output such as RESET.
- Heater break alarm Comparing the full load resistance value and the current load resistance value, if the current load resistivity is maintained under the P2-12 heater break alarm value for over 3 sec continuously, heater break alarm occurs. This alarm operates when control output is over 10% and load current is over 10% of the rated current. Output does not stop and operates normally.
