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 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.

Introduction
The SDM230* series are single phase two wire energy meters "with a
white back-lighted LCD screen for prefect reading". they are used to
measure single phase energy in residential and commercial applications.
The series contains 4 models: SDM230A, SDM230D,
SDM230DR,SDM230Bi
SDM230A : 1P2W energy meter with analog register
SDM230D : 1P2W energy meter with LCD display
SDM230DR: 1P2W energy meter with resettable partial energy
SDM230Bi : 1P2W energy meter with bi-directional measurement
SDM230DR and SDM230Bi have been MID approved. They measures
both active energy (kWh) and power (W). There are two buttons on the
front panel, one is used to scroll the info pages, another to reset partial
energy information. All models has a pulse output, which is passive type.
The constant is 1000imp/kWh.
