Three phase din rial meter
SDM530D
user manual
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 waterproof outdoor,
subject to local codes and regulations.
To prevent tampering, secure the meter with a padlock or a similar device.
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.
Connection of the wires should be done in accordance with the underneath connection
diagram.

Consumption indication
On the SDM530D’S front panel, there are four LED, in which three LED are for three phase voltage and
another one for impulse. The constant of the impulse is shown on the nameplate of the meter.
Reading the meter
The SDM530D energy meter is equipped with 6+1 or 5+2 LCD display, which is used as recording
consumption and can’t be reset to zero. The number system is based on units of 10. And unit is kWh.
On the front panel, there are two rubber buttons, which are used to scroll down the meter display
information.
Pulse output
SDM530D series 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,
