3. Safety Precautions

3.1 Precautions for Operating Environment and Conditions

This Unit is premised on being used in pollution degree II environment. When used in higher pollution degree, protect this Unit from pollution on another device side to be incorporated.

For the definition of the pollution degree and the over voltage category, refer to EN61010-1/2010.

Do not use this product in the places listed below. Failure to follow the instruction may cause malfunctions or decrease of product-life.

・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 IP address, Subnet mask, Default gateway existence and Default gateway address.

※Please refer to “user’s manual of EMU4-FD1-MB”.

3.3 Installation Precautions

・For installation and wiring works, make sure that the power source is shut off for all outside phases.

If all phases are not turned off, it may cause an electric shock or product damages.

・Any person who is involved in installation and wiring of this Unit should be fully competent to do this work.

・Work under the electric outage condition when installing and wiring. Failure to do so may cause electric shock or a failure of the Unit, a fire etc.

・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

・Do not install a twisted pain cable together with the main circuit and power cables, etc.

・Place the twisted pair cable in a duct.

(2) Communication system

・Increase the number of communication retries if necessary.

・Change the hub used for connection into a 10Mbps hub, and make communication at a transmission speed of 10Mbps.

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.

・Do not touch the live part. It may cause electric shock, electric burn injury or burnout of the device.

・Work under the electric outage condition when installing and wiring.

・Do not disassemble or modify this Unit It may cause failure, malfunction, injury or fire.

・Do not touch the MODBUS

®

TCP communication connectors when communicating. It may cause a malfunction or failure of the Unit.

・Push the RESET switch with an appropriate force (1.6N). The addition of force than necessary, it may cause a malfunction or failure of the Unit.

3.5 Maintenance Precautions

・Use a soft dry cloth to clean off dirt of the Unit surface. Do not let a chemical cloth remain on the surface for an extended period of time nor wipe the surface with thinner or benzene.

・Check for the following items to use this Unit properly for long time.

(1) No damage on this Unit

(2) No abnormality with LED indicators

(3) No abnormal noise, smell or heat

(4) No looseness with installation and wire connection

(Check item No.4 under the power failure condition. Failure to do so may cause electric shock, failure of the Unit or a fire.)

3.6 Storage Precautions

To store this Unit, put it in a plastic bag. For long-time storage, avoid the following places. Failure to follow the instruction may cause a failure and reduced life of the Unit.

・Places the ambient tempe rature exceeds the range -10-+60°C

・Places the average daily temperature exceeds +35°C

・Places exposed to rain, water drop or direct sunlight

・Places the Relative humidity exceeds the range 30-85% or places with dewfall

・Vibration and impact exceed the specifications

・Places metal fragments or conductive substance are flying

・Places where dust, corrosive gas, saline and oil smoke exist

3.7 Disposal Precautions

・When disposing of this Unit, treat it as industrial waste.
