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.
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.

Terminal Structures The terminal structures according to the models are described in this section: Structure of the MPR-27S-23 Terminal: Current Terminals: K1, L1, K2, L2, K3, L3 An external current transformer must be used for the 3-phase system connection to these terminals where the current up to 5A can be input. Supply Terminals: A1, A2 Please, apply 85-300 VAC/DC supply connection through these terminals.
As the OC terminal will be the joint point (reference), the O1 and O2 terminals are used as insulated outputs. As it can be seen from the following figure, these Open Collector outputs should be fed by an external supply for operation. 5-30 VDC Relay Coil O1 O2 MPR 2X OC Analog Output Terminals: AOC, AVO, AIO As the AOC terminal will be the joint point (reference), the analogue current or voltage output is ensured respectively through the AIO and AVO terminals.
Structure of the MPR-26S-21 Terminal: Different from the MPR27S-23, these terminals which are used for relay output are the terminals next to the voltage terminals. They are indicated with the key symbol on the front view. The terminal structure of the MPR26S-21 model is as in the following: Structure of the MPR-25S-22 Terminal: Different from the MPR27S-23, there is not any analogue output terminals on the MPR25S-22 model.
Structure of the MPR-24S Terminal: Different from the other terminal models, MPR24S model dost not have any I/O terminal. This terminal has only supply and measurement terminals.
CONNECTION TYPES As there are shunts at the current measurement inputs of the device, it is mandatory to use a current transformer except for the connections of current inputs. If, the device will be used on the same current line by means of analyzers with other shunts, it is recommended that the device is located at the extreme point. The device has 5 different connection types.
3P3W (Three-Phase Three-Wire) Connection As it is seen below, three voltage and three current connections are established in this connection type. ARON Connection Three voltage and two current connections are established in this connection type. As it is seen in the following figure, the current connections are established with the 1st and 3rd phases.
3P4W BLN (Three-Phase Four-Wire Balanced) Connection Four voltages and one current connection are established in this connection type. The device displays the value measured at the current input connected to the first phase on its screen for other phases in the same value. 3P3W BLN (Three-Phase Three-Wire Balanced) Connection Three voltage and one current connections are established in this connection type.
Connection Control After, the connections of the device are completed, you can check the connection you established by using the test functionality. The device switches into the connection test mode if the BACK button is pushed for 3 seconds. In this mode, at least 20% of the normal voltage and 10% of the nominal current must be applied on the measurement inputs of the device and the angle difference between the voltage and current inputs should be lower than 30 degrees.
Communication Line Termination Resistance If, the communication distance of RS485 lines is longer than 10 meters and there are more than one devices on the line, a 120 Ω line termination resistance should be installed between the A and B ends of the farthest device of the communication terminal. For this process, as it is seen from the following figure, it is enough to short-circuit the GND and TR terminals of the device.
