SDM530* Series is a range of 7 modules three phase four wire energy meters.
The series contains 2 models: SDM530D and SDM530D-2T.
SDM530D: measures and displays active energy(kWh)
SDM530D-2T: measures and displays active energy(kWh) in 2 tariffs.
2 tariffs: SDM530D-2T has a time relay inside which can monitor if there is
external 230V signal input. When It detected an external 230V signal input, the
meter switches to tariff 2 measurement. Otherwise it will measure as tariff 1.
With high accuracy of Class 1, they are widely used to measure three phase
energy in commercial and industrial applications. A pulse output is provided.

Information for your own safety
This manual does not contain all of safety measures for operation of the
equipment (module, device), because special operating conditions, and
local code requirements or regulations may necessitate further measures.
However, it does contain information which must be read for your personal
safety and to avoid material damages. This information is highlighted by a
warning triangle and is represented as follows, 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 commission, start
up, ground and label devices,systems and circuits according to safety
and 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 assembly, as well as proper
operation and maintenance. When operating electrical equipment, certain
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 used 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 your bare
hands, with metal, blank wire or other material as you may get an
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 functionality of the meter, and will avoid any warranty.
Do not drop, or allow physical impact to the meter as there are high
precision components inside that may break.

Meanwhile, the corresponding LED indicator on the front panel will flashes.
*SDM530D measures T1 Active Energy only.
When T1 is working, you will see on the display the symbol of "T1" is flashing.
When T2 is working, you will see on the display the symbol of "T2" is flashing.

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 capacity 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 buildings
electrical design and all local regulations.
The meter has to be installed against a wall which is fire resistant.
The meter has to be installed in a good ventilated and dry place.
The meter has to be installed in a protection box when placed in
dangerous or dusty environment.
The meter can be installed and used after being tested and sealed with
a letter press printing.
The meter can be installed on a 35mm DIN rail or direct on a meter board
with screws.
The meter should be installed in an available height so that it is easy
to read.
When the meter is installed in an area with frequent surges due to e.q.
thunderstorms, welding machines, inverters etc, protect the meter with
Surge Protection Devices.
After finishing installation, the meter must be sealed to prevent tampering.
Wiring of the wires should be done in accordance with the underneath
wiring diagram.
Wiring Diagram
Operation
LED indicator
On the SDM530D's front panel, there are four LEDs, in which top three
LEDs are for three phase voltage and the other one is impulse indication
for active energy measurement. The constant of the impulse is shown
on the nameplate of the meter. SDM530D-2T has one more LED impulse
indicator for the separate measurement of T1 and T2 active energy.
Reading the meter
The SDM530* energy meter is equipped with 6+1 LCD display, which is
used as recording consumption and can't be reset to zero. The unit is kWh.
The meter shows the following data:
2. T2 Active Energy
Pulse output
SDM530* 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. They are test pulse output (pins
8 & 9). Usually, the test pulse output is used as testing accuracy or reading
purpose in close quarters.
The test 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 be 5-27V DC, and the
maximum input current (Imax) should be 27mA DC. To connect the
impulse output, connect 5-27V DC to connector 9 (anode), and the
signal wire (s) to connector 8 (cathode). The meter pulse is indicated
on the front panel.
