SAFETY AND WARNING

Attention

If the following instructions are not carefully followed, the circumstances which can
cause death and serious injuries might happen.

 The installation of the device must be performed by the qualified and trained

personnel.

 Please, cut the whole power while installing the device. Please, use a suitable

circuit breaker on the installation terminal.

 You must connect the power lead-ins of the device by using a current

transformer. Do not apply direct current connection.

 Never, remove the front panel while the device is connected to the mains.
 Never, clean the device by any solvent or similar material. Only use dry cloth for

cleaning it.

 Before, turning on the device, make sure that the connections are correct.
 Please, contact your authorized dealer in case of any problem with your device.
 The device is only for interior electrical / fire enclosure panel type assembly.

Only the front panel of the device should be accessible from the switchboard.

 The fuse to be used must be CATIII and F type and the current limit value

should be 1A.

 Current measurement inputs must be connected with auxiliary current

transformers which have reinforced insulation.

 The power meter shall not be used for primary protection or applications where

its failure can cause harm or death.

 Please de-energize the device before replacing RTC backup battery. It must be

Li/MnO2 battery.

The manufacturer firm cannot be held responsible in any way for any circumstance
which might arise if the aforementioned precautions are not implemented

.

Safety

Please, read the entire operating manual before using the device.

 Connect a button or a circuit breaker between the mains and the supply inputs

of the device.

 The button or circuit breaker to be connected should be close to the device.
 It should be labeled that the button or circuit breaker to be connected will be

used for separating the device from the mains.

 This device is used for analyzing the electricity mains and it must not be used for

main protection function.

Guarantee

The guarantee term of the device is 2 (two) years. In case of any problem, the repair of
the device must be done only by the manufacturer firm; otherwise, the guarantee of the
device becomes invalid.

Applications

This is a MPR-2 series 3-phase mains analyzer. It is a microprocessor based device which is designed
for measuring all parameters of an electricity main; calculate consumptions and transferring desired
parameters with Modbus and I/O outputs.

Thanks to its clock chip and flash memory of the device, the blackout logs and the processes performed
by the operator such as the time and setting changes, resets and etc. are saved in real time. These logs
can be read and followed by the Modbus RTU protocol through the RS-485 communication port.

Current connection is done according to the selected model through 5A direct connection to the current
transformer with CT25 and RJ-45 connector and mV voltage output.

The connection control function which is described in detail in the 15th page should be used against
open live ends due to possible fractures at terminals.
