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.

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.
