Purpose
Functioning
A special electronic system under the influence of flowing current
and applied voltage generates pulses proportional to the drawn
energy. Energy consumption is indicated by a flashing LED. The
amount of pulses is converted into energy input, and its value is
displayed by the segment LCD display. The fractional digits repre-
sent the hundredths (.01 kWh = 10 Wh).
MID Directive 2014/32/EU
DEC-1 is a static (electronic) calibrated electricity meter of single-
phase alternating current in a direct system.
Pulse 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.

Assembly
1. Disconnect the power.
2. Mount the indicator on a rail in the distribution box.
3. Connect input phase to terminal 1. Connect wire N to terminal 4.
4. Connect a measured circuit or a single receiver to terminal 3
(output phase L) and to terminal 6 (N).
5. Optionally connect the RS-485 network wires to the 20 (A+) – 21
(B–) terminals.
6. Put the covers on the terminals and optionally seal them.

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
claims on the counter
