ETI DEC-2 User manual

Meter front descriptionPulse output
The meter is equipped with pulse output SO+ – SO-. This allows you
to connect another pulse device (SO) that reads pulses generated
by the meter.
No additional connected equipment is required for proper opera-
tion of the meter.
Sealing
The meter has sealable input and output terminal covers to pre-
vent any attempts to bypass the meter.
Meter number
The meter is marked with individual serial number allowing its
unambiguous identification. The marking is laser engraved and
cannot be removed.

phase alternating current in the system directly.
is a static (electronic) indicator calibrated electricity three-
A special electronic system under the influence of current flow and
applied voltage in each phase, generates pulses in proportion to
the electricity consumed in this phase. Phase energy consump-
tion is indicated by flashing the corresponding LED (L1, L2, L3). The
sum of the pulses of the three phases is indicated by a flashing LED
shall be converted to energy, taken throughout the three-phase
system, and its value is determined by the segment LCD display.
Decimal represent the hundredths (.01 KWh = 10Wh).

Assembly
1. Disconnect the power supply.
2. The indicator mounted on a rail in the distribution box.
3. Using a screwdriver, remove the screws and remove the front
shield meter terminals.
4. Power supply connected to the terminals 1 (L1), 3 (L2), 5 (L3).
5. Measuring circuit or a single receiver connected to terminal 2
(L1), 4 (L2), 6 (L3).
6. Connect the cable to the terminal N 7.
7. Additional pulse receiver connected to terminals 20(+)–21(–).
The terminals are located under the top shell meter terminals.
NOTE!
Additional pulse receiver is not required.
8. Install shield meter terminals.

General safety conditions
* Please read the manual carefully prior to installing the meter.
* The meter should be installed and operated by qualified person-
nel familiar with the construction, operation and any hazards
involved.
* Do not install the meter if it is damaged or incomplete.
* The user is responsible for proper grounding, selection, instal-
lation and functionality of any other devices connected to the
meter, including security devices such as overcurrent protection
breakers, differential switches and surge protectors.
* Before connecting the power supply make sure that all cables are
connected properly.
* Always follow the operational conditions of the meter (voltage,
humidity, temperature).
* In order to avoid electric shock or damage to the meter, discon-
nect the power before each change in connection configuration.
* Do not modify the device on your own, as this may cause damage
or improper operation of the meter and consequently expose
the users to risk. In these cases the manufacturer is not liable for
ensuing events and reserves the right to refuse the warranty
