・Places the Ambient temperature exceeds the range-5-+55°C
・Dust, corrosive gas, saline and oil smoke exist
・Places the Relative humidity exceeds the range 30-85% or places with dewfall
・Places exposed to rain or water drop
・Operating altitude exceeds 2000m
・Vibration and impact exceed the specifications
・Places metal fragments or conductive substance are flying
・Places the average daily temperature exceeds +35°C
・Places in strong electromagnetic field or places large amounts of external noise exist
・Places exposed to direct sunlight

This unit is the open type device, which are designed to be housed within another device for prevention of electric shock. House this unit within the device such as the control panel
before use. (Indoor use)

3.2 Matters concerning the precaution before use

・Use the Unit in the specified usage environment and conditions.
・Before using this Unit, set MODBUS

TCP communication

・In 100Mbps communication by the 100BASE-TX connection, a communication error may occur under the influence of high frequency noise from devices other
than this device in the installation environment.
・Take the following action to prevent the influence of high frequency noise in the construction of a network system.
(1) Wiring connection

CAUTION

3.4 Precautions for Use

・

Before operating the product, check that active bare wire and so on does not exist around the product. If any exposed conductor is found, stop the operation immediately and take

an appropriate action such as isolation protection

・In the event of a power outage during the setting, the Unit is not set correctly. Please set again after power recovery.
・When you connect to Energy Measuring Unit of the Unit, Contrast of the LCD display of Energy Measuring Unit is reduced to small.
