contatore trifase di energia elettrica contatore enel monofase/trifase

CONTATORE TRIFASE DI ENERGIA ELETTRICA Lo strumento in questione occupa 4 DIN (4X18 mm) e si alloggia facilmente in un normale quadretto, che
abbia la guida DIN, lo strumento va installato a “monte” dei dispositivi di protezione, poiché una eventuale
condizione di guasto non deve potersi propagare attraverso lo strumento (esempio un corto circuito),
l’alimentazione (INGRESSO) dello strumento avviene attraverso i morsetti inferiori L1 L2 L3 e L4/N
(quest’ultimo è il neutro, se esistente), mentre L’USCITA è in corrispondenza dei morsetti superiori L5 L6 L7.
I morsetti so+ ed so-, servono per poter collegare lo strumento ad un sistema di acquisizione dati, per
esempio un plc, arduino ecc, e fornisce in uscita un impulso di caratteristiche note (vedere tab sottostante), I
LED di segnalazione si accendono quando lo strumento è alimentato (Led Verde, Giallo e Rosso si
illuminano se vi è presenza della fase corrispondente), se c’è consumo il led di destra farà dei lampeggi
rossi, maggiore è la frequenza di lampeggio maggiore è il consumo, ogni 400 lampeggi viene registrato 1
kWh, quindi ogni 40 lampeggi viene registrato un decimo di kWh, il display, retroilluminato di BLU, mostra
il consumo registrato, con una precisione del decimo di kWh, l’ultima cifra registrata (dopo la virgola)
rappresenta il decimo di kWh.

depending on the degree of potential danger.
Warning
This means that failure to observe the instruction can result in death, serious injury or
considerable material damage.
Caution
This means hazard of electric shock and failure to take the necessary safety
precautions will result in death, serious injury or considerable material damage.
Qualified personnel
Operation of the equipment (module, device) described in this manual may only be performed by
qualified personnel. Qualified personnel in this manual means person who are authorized to

Regulatory standards.
Use for the intended purpose
The equipment (device, module) may only be used for the application specified in the catalogue and
the user manual, and only be connected with devices and components recommended and approved
by Eastron.
Proper handling
The prerequisites for perfect, reliable operation of the product are proper transport, proper storage,
installation and proper operation and maintenance. When operating electrical equipment, parts of this
equipment automatically carry dangerous voltages. Improper handling can therefore result in serious
injuries or material damage.
 Use only insulating tools.
 Do not connect while circuit is live (hot).
 Place the meter only in dry surroundings.
 Do not mount the meter in an explosive area or expose the meter to dust, mildew and insects.
 Make sure the wires are suitable for the maximum current of this meter.
 Make sure the AC wires are connected correctly before activating the current/voltage to the
meter.
 Do not touch the meter connecting clamps directly with metal, blank wire and your bare hands as
you may get electrical shock.
 Make sure the protection cover is placed after installation.
 Installation, maintenance and reparation should only be done by qualified personnel.
 Never break the seals and open the front cover as this might influence the function of the meter,
and will cause no warranty.
 Do not drop, or allow strong physical impact on the meter as the high precisely components inside
may be damaged.

Installation should be performed by qualified personnel familiar with
applicable codes and regulations.
Use isolated tools to install the meter.
Fuse or thermal cut-off or single-pole circuit breaker can’t be fitted on the
supply line and not the neutral line.
Don’t put your finger into the hole, because there is a screw inside.
Please choose the available adapter which is supplied with the meter to suit
the diameter of the cable.
We recommend that the connecting wire which is used to connect the meter to the outside circuit
should be sized according to local codes and regulations for the amp city of the circuit breaker or over
current device used in the circuit.
An external switch or a circuit-breaker should be installed on the inlet wire, which will be used as a
disconnection device for the meter. And there it is recommended that the switch or circuit-breaker is
near the meter so that it is more convenience for the operator. The switch or circuit-breaker should
comply with the specifications of the building electrical design and all local regulations.
An external fuse or thermal cut-off which will be used as an over-current protection device for the
meter must be installed on the supply side wire, and it is recommended that the over-current
protection device is near the meter so that it is more convenience for the operator. The over-current
protection device should comply with the specifications of the buildings electrical design and all local
regulations.
This meter can be installed indoor directly, or in a meter box which is waterproofed outdoor, subject
to local codes and regulations.

1.7 Operating
Consumption indication
There is a red LED which is used as indicating power consumption in the front panel of SDM630D .
When consumption happens, the LED will flash. The more quickly LED flashes, the more consumption
there is. For this LED, the flash rate is indicated per kWh on the front panel.
Reverse indication
There is in the front panel a red LED which is used as indicator when reverse current happen.
Communication indication
Reading the meter
The SDM630D energy meter is equipped with 5+2 LCD display, which is used as recording
consumption and can’t be reset to zero.

Three phase din rail meter SDM630D user manual
Pulse output
The SDM630D DIN rail energy meter is equipped with a pulse output which is fully separated from the
inside circuit. That generates pulses in proportion to the measured energy for accuracy testing.
The pulse output is a polarity dependant, passive transistor output requiring an external voltage
source for correct operation. For this external voltage source, the voltage (Ui) should is 5-27V DC, and
the maximum input current (Imax) is 27mA DC. To connect the impulse output, connect 5-27V DC to
connector 6 (anode), and the signal wire (S) to connector 5 (cathode). The meter pulses is indicated
on the front panel.
