Safety Instructions
Information for your own safety
This manual does not contain all of the safety measures for operation of
the equipment(module,device),because special operating conditions,
and local code requirements or reg ul ation s may necessitate further
measures. However,it does contain info rm ation w hich mu st be read
for your personal safety and to avoid material damages.This information
is highlig hted by a wa rn ing tri angle a nd is repres en ted as follo ws,
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
Thi s means hazard of ele ctric s hock an d fai lu re 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
thi s manua l means person who ar e 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.

The SDM72* series are three phase four wire energy meters “with a
white back-lighted LCD screen for prefect reading”. they are used to
measure three-phase energy in commercial and Industrial applications.
The series contains 3 models: SDM72D, SDM72DR, SDM72Bi
SDM72D measures and displays active energy (kWh) ;
SDM72DR measures and displays active energy (kWh)and power (W),
a resettable active energy value is available.
SDM72Bi measures and displays the total/import/export active energy
and power. resettable energy is also available.
There is a button on the front of SDM72DR and SDM72Bi. The button
has two functions: 1 short click the button to scroll the display , 2. press
down and hold the button for 3 seconds to reset the resettable energy
value.
Super-capacitor is optional. If the meter has super-capacitor inside , the
meter display can keep on power for 1 week when external power supply
is off.
