Panasonic KW4M User Manual

iCautions before using■ Installation environment◇Do not use the Unit in the following environments.・Where the unit will be exposed to direct sunlight and where the ambient temperature is outsidethe range of -10 to 50 °C.・Where the ambient humidity is outside the range of 30 to 85 % RH (at 20℃ non-condensing)and where condensation might occur by sudden temperature changes・Where inflammable or corrosive gas might be produced・Where the unit will be exposed to excessive airborne dust or metal particles・Where the unit will be exposed to water, oil or chemicals・Where organic solvents such as benzene, paint thinner, alcohol, or strong alkaline solutionssuch as ammonia or caustic soda might adhere to the product・Where direct vibration or shock might be transmitted to the product, and where water might wetthe product◇Please use the Unit according to the specifications described in this manual. Otherwise, itmay malfunction or cause fire and an electric shock.・Connect to the power supply in compliance with the rating.・Refer to the wiring diagram to ensure proper wiring for the power supply, input and output.・Do not perform wiring or installation with a live line. It may also lead to circuit burnout or fire byway of the secondary CT side opening.・Do not add voltage and current to an output terminal from outside.・Do not use at secondary side circuit of inverter.■ Installation・Installation and wiring must be performed by expert personnel for electrical work or electricpiping.・The power supply terminal and voltage input terminal of the main unit is common. Therefore ifadditional noise effects the power supply line, incorrect measurements may result.・Eco-POWER METER is designed to be used in a control panel.･As to measurementIf there is some distortion by harmonic or waveform, it may not measure correctly.Please check with the actual system before adopting it.■ Static electricity・Discharge static electricity touching the grounded metal etc. when you touch the unit.・Excessive static electricity might be generated especially in a dry place.■ Cleaning・Wipe dirt of the main unit with soft cloth etc. When thinner is used, the unit might deform or bediscolored.■ Power supply・Connect a breaker to the voltage input part for safety reasons and to protect the device.The breaker that connects to the voltage input part must arrange at the position easily reached,and display shows it is the breaker of the equipment.・Do not turn on the power supply or input until all wiring is completed.■ Before power onPlease note the following points when turning on power at the first time.・Confirm there are neither wiring rubbish nor especially an electrical conduction when installed.・Confirm neither the power supply wiring, the I/O wiring nor the power-supply voltage are wrong.・Tighten the installation screw and the terminal screw surely.・Use an electric wire applicable to the rated current.
