2. Installing and Configuring Hardware Value 11 Setting (Baud Rate) 19,200 2.2.4 Mounting sensors The sensors that measure electrical parameters are connected to an EMU. The sensors are fixed on power cables. So please keep the following cautions:
DANGER CAUTION CAUTION CAUTION CAUTION The clamp must be attached to the wire with 300 V insulation capability. Before installing a sensor, please check no current flows into the cable. Clean the surface of the cable. Otherwise, foreign materials can cause a malfunction or incorrect measurement. If phase allocation is wrong, incorrect energy data will be collected. The allowable number of clamp openings is 50 times or below. Frequent clamp openings may shorten the life of clamp. To mount a sensor on the target cable, perform the following steps:
1. Place the sensor on the target cable according to the specified phase. 2. Keep the direction of the arrow sign on the sensor same as the current flow direction. 3. Close the sensor clamp over the cable. 4. To fix the sensor on the cable, use the cable tie.

The reset command resets the energy counters, the recording interval counters, and the on-going interval accumulated values. The time-stamp of the energy counters is written into the register when the data is sent to EMG. Energy counters will count positive for energy consumed, negative for energy generated and pushed into the grid. Active, reactive, and apparent energy consumption values are stored as 32-bit values, thus using 2 Modbus registers. The lower register address contains the high word value (MSW: Most Significant Word) and the high register contains the low word value (LSW: Least Significant Word). Registers: 0 to 23. 0 16-bits MSW 1 16-bits LSW

4. Software Interfaces 4.1.10 Recording interval time (register 64) Energy is integrated based on the recording time interval that is configurable. The normal energy is calculated based on the period of five minutes with nominal current and nominal input voltage. The last completed interval values are stored in the register map. The time-stamp is set in the time-stamp register at the end of the integration interval. Registers: 32 to 43 4.1.11 Recording interval-based energy The recording interval time is a configurable parameter that defines the recording interval (minutes). It can have values for 5, 6, 10, 12, 15, 20, and 30. The start of an interval is at the hour + n* interval. When writing a value different from the ones listed to this parameter, it is discarded and the EMU continues to use the previous set value. Note that the EMG responds with an "ACK" to a write of an invalid value as it does not check the contents of the message sent to the EMU. 4.1.12 Time stamp The time stamp of the recording interval have the same format that uses three Modbus registers. Each of the registers is split into two parts as shown in the following table. Register 28 29 30 24 25 26 High Byte Minute Day Year Low Byte Second Hour Month 4.1.13 Frequency (register 27) The Line Frequency is measured based on the phase of the power supply only (phase 1). The last value of the recording interval is stored in this register.

4. Software Interfaces 4.1.14 Maximum current The RMS current is averaged for 10 line periods (200 ms in the 50 Hz system). The maximum current average of the recording interval is stored in this register. 4.1.15 Minimum voltage The RMS voltage is averaged for 10 line periods (200 ms in the 50 Hz system). The minimum voltage value of the recording interval is stored in this register.

4. Software Interfaces 4.1.17 Software version The software version means the major release number of the EMU software. The MSB of this register contains the version number. The LSB of this register contains the revision number. 4.1.18 Status word The status of the EMU can be read from a read-only register.

Setting a bit in the command word executes the command. Bit 0 7 Command This resets the device counters and the interval counters. Places EMU in direct serial communication mode. It is used during manufacturing. Do not place EMU in this mode. Otherwise the EMU cannot communicate via the radio module. In this mode, turn off and on the device to reset to normal radio communication. 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15 Not used/ignored The reset meter command resets the energy counters to zero in both RAM and non-
volatile RAM. This command does not affect the reporting intervals.
