2Safety
2.1 Safety requirements
Installing, uninstalling, parameterization and verification can be performed only by authorized
organizations that have qualified technicians. Only qualified persons should install DCU.
DCU connection or disconnection from network should be done when voltage in the network is turned
off. A protection from accidental network voltage connection must be established.
No accessories can be hanged on a DCU, it is forbidden to hit or strike DCU case.
Precautions must be taken in battery changing procedure:
A. DCU has to be disconnected from electricity network, a protection from accidental network
voltage connection must be assured;
B. Use pincers or similar instruments to change battery (connection/disconnection of a plug).
2.2 Transportation and storage rules
Prior to the usage DCU must be kept in a closed room in a transportation packing, where the temperature
ranges from 5°C to 40°C and average area humidity is up to 80% when temperature being 25°C. The room
must be without harmful gas or steam. DCU must be kept and exploited in premises protected from dust,
aggressive vapors and gasses.
Unpacked DCU can be kept only in repair workshop. The temperature must range from 10°C to 35°C,
average area humidity must not exceed 80% when temperature being 25°C.
During wintertime DCU must be kept in a heated room for 6 hours or more, before they are used.
DCU must be transported only in closed vehicles (carriage, container, hold). Shake acceleration can not
exceed 30m/s², 80-120 strikes per minute. The temperature must be within -40°C to +70°C range,
average area humidity must not exceed 98% when temperature being 35°C.
2.3 Prevention and elimination of malfunctions
If suspected that DCU works improperly, the following actions should be performed:
Exterior inspection. Before applying voltage to the DCU, make sure its case has no mechanical damages,
there are no signs of overheating, and all wires are properly connected.
Do not plug a concentrator into power network if it is mechanically damaged. This can cause staff
injuries and destroy DCU as well as other equipment!
Inspection of connection and parameterization constants. Installing, uninstalling, parameterization and
verification can be performed only by authorized organizations that have qualified technicians. After
plugging a DCU into electric network technician should check whether date and time are correct, set
concentrator IP and gateway addresses according user network requirements.

Procedure of returning DCU to manufacturer. In case malfunctions cannot be eliminated on the spot, the
DCU should be returned to the manufacturer for repair or replacement. DCU upon return to manufacturer
must have Passport with notices of organization in charge of their exploitation and short description of
DCU malfunctioning.

DC12U has 512 MB RAM and 4096 MB Flash. DC12U is designed to support up to 500 meters.

DC12 PLC Data Concentrator User Manual

DC12U uses two-way communication in both PLC and cellular networks for metering data reading and
meter/PLC data device management.
PLC modem fully integrated inside DC12U data concentrator. Modem is based on ST8500 solution and is
operating using G3 PLC technology. DC12U PLC modem supports FCC (150-490kHz) or CENELEC-A (35-
91kHz) frequency bands. Electromagnetic emissions of the modem does not exceed standardized values
according EN55022 when operating at above two frequency bands.
DC12U PLC modem ensures PLC MAC security according G3 PLC technology by using 128 bit length pre-
shared key (PSK). DC12U will be configured with purchaser provided PSK.
DC12U data concentrator supports remote and local configuration possibility for G3 PLC modem, change
modem parameters, change used frequency band. Data concentrator G3 PLC modem uses all three
phases for PLC communication with meters.
GSM 2G/3G/4G modem is based on CE certified Quectel EG91-E LTE module. For data transfer modem
uses IPv4 protocol. Modem is DCU module installed in DCU compartment for communication modules.
Modem SIM card is protected with cover on modem housing top. Modem cover construction enables
open it by hand and SIM card is accessible without any instrument. Communication modules
compartment cover may be sealed, so modem is protected from unauthorized access. Modem has
antenna with electrically isolated body. Antenna connected to modem using SMA type connector.
After power on, data concentrator automatically registers all available electricity meters. In normal
conditions, data concentrator periodically checks meters accessibility on PLC network and checks for new
meters events. All mentioned operations periodicity configured by user locally or remotely. If new meters
events are available, DC12U reads them from meter and stores in local database for transfer to HES.
DC12U configuration (parametrization) and FW update can be complete locally by using WEB GUI or
remotely by using HES. For local DCU management WEB GUI is used. WEB GUI is accessible over any
Ethernet port or through mobile connection.
