Safety Instructions
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.

Description
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.
