DANGER
- The input/output terminals are subject to electric shock risk. Never let the input/ output terminals come in contact with your body or conductive substances.
WARNING
- This product does not contain an electric switch or fuse, so the user needs to install a separate electric switch or fuse externally.(Fuse rating: 250 V 0.5 A)
- To prevent defection or malfunction of this product, supply proper power voltage in accordance with the rating.
- To prevent electric shock or malfunction of product, do not supply the power until the wiring is completed.
- Since this product is not designed with explosion-protective structure, do not use it any place with flammable or explosive gas.
- Do not decompose, modify, revise or repair this product. This may be a cause of malfunction, electric shock or fire.
- Reassemble this product while the power is OFF. Otherwise, it may be a cause of malfunction or electric shock
- If you use the product with methods other than specified by the manufacturer, there may be bodily injuries or property damages.
- Due to the danger of electric shock, use this product installed onto a panel while an electric current is applied.
CAUTION
- The contents of this manual may be changed without prior notification.
- Before using the product you purchased, make sure that it is exactly what you ordered.
- Make sure that there is no damage or abnormality of the product during delivery.
- Do not use this product at any place with corrosive(especially noxious gas or ammonia) or flammable gas.
- Do not use this product at any place with direct vibration or impact.
- Do not use this product at any place with liquid, oil, medical substances, dust, salt or iron contents. (Use at Pollution level 1 or 2)
- Do not polish this product with substances such as alcohol or benzene.
- Do not use this product at any place with a large inductive difficulty or occurring static electricity or magnetic noise.
- Do not use this product at any place with possible thermal accumulation due to direct sunlight or heat radiation.
- Install this product at place under 2,000m in altitude.
- When the product gets wet, the inspection is essential because there is a danger of electric leakage or fire.
- If there is excessive noise from the power supply, using insulating transformer or noise filter is recommended. The noise filter must be attached to a panel which is already connected to a ground and the wire between the filter output and power supply terminal must be as short as possible.
- If puttig power cables closely together then It is effective against noise.
- Do not connect anything to the unused terminals.
- After checking the polarity of terminal, connect wires at the correct position.
- When this product is connected to a panel, use a circuit breaker or switch approved with IEC947-1 or IEC947-3.
- Install the circuit breaker or switch at near place for convenient use.
- Write down on a label that if the circuit breaker or switch is operating then the power will be disconnected since the circuit breaker or switch is installed.
- For the continuous and safe use of this product, the periodical maintenance is recommended.
- Some parts of this product have limited life span, and others are changed by their usage.
- The warranty period for this product including parts is one year if this product is properly used.

Function mode
Function Mode Configuration
- The function mode consists of 4 parameter groups: P.FUN / P.EXP / P.OUT / P.OPT.
- P.FUN is a group of general function setting parameters.
- P.EXP is an extended function setting parameter group.
- P.OUT is a group of output function setting parameters related to the output model.
- P.OPT is a group of optional function setting parameters related to transmission output and communication output models.
- Press the
key for more than 3 seconds in the operation mode to enter the function mode.
- In function mode, if
key is pressed for more than 3 seconds, all parameter values are saved and operation mode is restored.
- FREQ is displayed only on AC models (when FREQ is selected, AC.TY / EX.IN / K-ZO is not displayed)
- AC.TY displayed on AC models only (AVG / RMS selected)
- P.OUT is displayed only on the output model (if O-MD is OFF, S.TMR / HYS is not displayed)
- P.OPT is displayed only in transmission output and communication output models
- PV.SH/PV.SL is displayed only in transmission output model
- S-NO / BPS / PTY / RWT / CWP are displayed only in communication output model
