◈ It shows that V1, V2, V3, V12, V23, V31, I1, I2,
I3, S1, S2, S3, F1, F2, F3
◈ It shows the minimum, maximum and
average values of V1, V2, V3, V12, V23, V31,
F1, F2, F3
◈ It shows the minimum, maximum, average
and demand values of I1, I2, I3, S1, S2, S3
◈ High/Low voltage, current, frequency
(adjustable)
◈ Phase-Neutral or Phase-Phase protection
(adjustable)
◈ 1x Relay output
◈ Protect Voltage, Current and Frequency
◈ Shows phase sequence
◈ Can delete the demands

1 - It shows phase number belong to measurement values
2 - Showing values are minimum of measurement values
3 - Showing values are maximum of measurement values
4 - Showing values are average of measurement values
5 - Showing values are demand of measurement values
6 - It shows Serial Communications
7 - It shows that type of measurement values
8 - It shows number of error
9 - It shows relay state. OUT1▬ means that relay is close, OUT1 — means that relay is open
10- It shows phase sequence. "L123" means that phase sequence is correct. "L132"means that phase sequence is incorrect.

Warnings

▲Use the device according to the instructions specified by us.

▲Do not expose the LCD display directly to sunlight in order to avoid any harm on it.

▲Note that the temperature level on the panel to which the device is mounted is at the range ofoperating temperature of the device (-20°C.....55°C).

▲There must be a space of 5cm behind the device after its installation.

▲Fix the device securely to the front-cover of the panel with the apparatus delivered together with the device.

▲Be sure that the panel to which the device is mounted does not operate in a humid environment.

▲Place the switch or circuit breaker close to the device or in a location that is easily accessible for theoperator.

▲Place a switch or circuit breaker on the system during installation of the device.

▲Please note that the cables must not be energized during installation.

▲Flexible monitored and twisted cables must be used for the input and output lines which are notconnected to the mains.

▲The technical personnel according with the instructions specified in the user's manual must performinstallation of the device and electrical connections.

▲The feeder cables must be compatible with the requirements of lEC 60227 or lEC 60245

Start-up of the Device:

Read the warnings before the device is energized. Make sure that the device is connected according tothe connection diagram. When the device energized for the first time, the Home Screen is displayed. Enterthe current transformer ratio and the voltage transformer ratios*, if installed, on the settings menu at first.
*The EM-07-XXD and EM-07E-XXD do not require current transformer ratios

Points to take into consideration in the selection and connection of Current Transformer

Be sure that the current transformer value is higher than the maximum current drawn from the system.

In order to prevent any mistake while connecting the output terminals of the curent transformer, use cables in different colors for each phase or designate a number for each cable.

Keep the cables connected to the output terminals of the current transformer away from the high-voltage line.

In order to prevent any shake on the current transformer, fix it on the bus-bar, cable or rail.

Maintenance

Switch off the device and release from connections. Clean the trunk of device with a swab. Don’t use any conductor or chemical might damage the device.
Make sure device works after cleaning.
