9 of 23 4 Function Characteristics 4.1 Clock Management DCU has a RTC which complies with IEC 62052-21/62054-21. At reference voltage and reference temperature (23C), clock accuracy is better than 0.5 s/day. The RTC supports leap year, day light saving time. In case of power off, clock of DCU is active for at least two years after manufactured with battery support. DCU automatically synchronizes its clock with SNTP server every day. The central system can synchronize the DCUs clock. When the DCUs clock is invalid, DCU will not automatically collect the data from meters. 4.2 Synchronize Meter Clock DCU automatically synchronizes the clock of the meters once a day. DCU interrogates the clock of meters. Depending on the clock difference, DCU take following action:

Clock difference 10 minutes 5 minutes And < 10 minutes

< 5 minutes DCU action Record a clock over limit event for the meter. Set the clock of meter No action, the meters clock will be synchronized in next days clock synchronization procedure of DCU. 4.3 Node Discovery and Auto-routing DCU automatically discover the new-installed RF repeater. Automatically routing will be provided by DCU for RF repeater. DCU supports maximum two levels of RF repeater. Once DCU discovers new meter, if the meter is not registered in the DCU, DCU will report this meter to central system, then central system will download the meter archive information into DCU. 4.4 Automatically Meter Data Collection DCU automatically collects the data from single phase meter, three phase meter with direct connection and three phase meter with CT connection. The data type for automatically connection includes monthly billing data, daily profile data, load profile data, and meter event logs. It is configurable to enable or disable the data collection for each type of data. 4.4.1 Re-collect the Data In case of missing some data for the meters, DCU will automatically re-collect it from the meters:

Data Type Re-collection Period Monthly billing data Last month Title:

Data Type Monthly billing data Daily profile data Energy load profile Capacity 13 months 32 days 4 days Power quality load profile 4 days Event logs 200 events for each meter The data will be first in first out (FIFO). 4.4.3 Data Upload to Central System Central system can read the meters data stored in DCU through DLMS protocol via the DCUs WAN communication port. The new read data will be compressed in files and sent to the central system by FTP. It is configurable for the FTP data uploading schedule. 4.5 On Demand Request and Response Transferring DCU works transparently to get the on request from the central system, and transfer the request to specified meter, and transfer the response from the meter to the central system. DCU does not interpret the request and response. The request to meter includes but not limit to:

1) Read meter energy registers, instant parameters, other registers 2) Read tariff schedule 3) Read clock 4) Set meter parameters, tariff schedule 5) Set tariff schedule 6) Set clock 7) Connect or disconnect the meter 8) Read monthly billing data, daily profile data, load profile data. 4.6 DCU Firmware Upgrade DCUs firmware is upgradable from the central system through FTP protocol. DCUs firmware is also upgradable from the central system or optical port through DLMS protocol. 4.7 Meter Firmware Upgrade Central system can request DCU to upgrade the meters firmware. DCU will firstly download the meter firmware from central system via FTP protocol, then start to download the firmware to the meters. The meter firmware upgrade procedure compliant to the DLMS firmware upgrade procedure. Title:

17 of 23 8.4 Installation Guide 8.4.1 What You Need To install DCU, you should prepare:

Screw driver: FD3 screw driver for main terminal screw. Fixing screw and Hook screw: M5 slotted countersunk (flat) head tapping screw. Electric drill with M3 broach for metal meter box installation. Electric drill with M5 broach and plastic plug for concrete wall installation. 8.4.2 DCU Installation Cut off the power supply to where the DCU will be installed, this is the most important thing!!!

Step 1: Inspect DCU before installation Before installation, please make sure there is no damage, broken or other defect on DCU. If defect is found, please dont install the DCU. Step 2: Fixing DCU is 3-point mounting system, fixed by 1 hook and 2 fixing screws. To fix DCU, hang the DCU by hook then fasten two fixing screws. Title:

AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page:

18 of 23 Step 3: Install RF antenna 1) Remove the RF antenna cover A: Hook, B: Fixing hole 2) Connect tightly the RF antenna to the RF antenna connector 3) Remove the cut-out of the RF antenna cover 4) Install the RF antenna cover, the RF antenna cable should pass through the cut-out 5) Fix the screw 6) Seal the RF antenna cover. Note: Before install the RF antenna, you may need to fix the RF antenna on the cabinet of the DCU. Make sure the RF antenna is fixed in the top right direction, and Antenna location according to actual can be installed at the scene of the adjustment. Step 4: Install 3G SIM card (2FF SIM card) 1) Open the SIM card seal rubber. 2) Insert the SIM card into the slot with right direction, and make sure the SIM card is installed rightly. 3) Close the SIM card seal rubber, and make sure the slot is totally sealed. Note: Its better to install the SIM card without removing the 3G module from the DCU. It is important to seal the slot with the rubber completely. Title:

AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page:

19 of 23 Step 5: Install 3G external antenna Tightly connect the external 3G antenna to SMA connector on the 3G module. Note:

1) Its better to install 3G antenna without removing the 3G module from the DCU. 2) Before install the 3G antenna, you may need to fix the 3G antenna on the cabinet of the DCU. Make sure the 3G antenna is fixed at the bottom of the 3G module, and as show in figure shows are as follows.(The antenna has been fixed on the bottom of the 3G module with 3m glue) 3) After installed the SIM card and 3G antenna, please check if the 3G module is tightly connected to the main box of DCU. Step 6: Connect the power wires Connect the power wires according to the marking on the terminals. Note:

1) To insure the reliable connection, install torque must higher than 3.5Nm. 2) The wire sequence from left to right be neutral, L1, L2, L3. It is important to have a right phase sequence. Single-phase power supply is recommended to connect neutral and L3. 3) It is proposed to install a fuse-controlled disconnect switch before the DCU, so that it is easy to power off the DCU for any maintain purpose. Title:

AJ102 Data Concentrator Unit User Manual Ver. 1.4 Page:

20 of 23 Step 7: Power on inspection After right connection of power wires, turn on the power. Inspect LED status according to chapter 4.10. 1) PWR LED should be on. 2) WCSQ LED should be on, or at least blink. 3) Res. LED should not be always on. 4) RF LED should not be always on. 5) ALARM LED should not be on. If WCSQ LED is off, it means 3G signal quality is very low, please try to adjust the position the 3G external antenna. If WCSQ is still off, there will be no connection the 3G. If ALARM LED is on, it means there is some failures on DCU. Please contact the expert or replace to install a new DCU. If the 3G parameter (APN, user, and password etc.) and HES parameter (server IP, port no etc.) is configured before the installation, the DCU will try to dial 3G and connect to the HES. After successfully connect to HES, the WLNK LED will be on or blink. Note: before power on DCU, please make sure 3G module is tightly connected to the DCU box. Step 8: Configure the communication parameters (This step is needed only if DCU is not rightly configured before installation) Use configuration software to configure the right 3G communication parameters (APN, user name, password etc.), and HES communication parameters (server IP, port no etc.). Use configuration software to send a reboot command to reboot DCU. After reboot is finished, DCU tries to connect to HES. After successfully connect to HES, the WLNK LED will be on or blink. Note: It is strongly proposed to configure the DCU communication parameters before installation of DCU. Step 9: Install the terminal cover 1) Install the terminal cover tightly 2) Fix the terminal screws 3) Seal the terminal cover screws. The installation of DCU is finished. Note The detail installation guide in the box refers to Meter and Meter Box Installation Specification.pdf. Title:
