Initialization Display
When it is powered on, the meter will initialize and do self-checking.
After the self-checking program, the meter screen will display the total active
energy (kWh)
* Note: For the M ID version of SD M120CTM, S DM 120CT MB and S DM120CT P, the
CT ratio can be set only once. Before you set the CT ratio, please check the ratio
of the CT connected to the meter. For example, if the CT is 100/5A, please set CT1
to be 100.
Scroll Display by button
There is a button on the front of the meter. After initialization and self-checking
program , the meter display the measured values . The default page is total
kWh. If the user wants to check other information, he needs to press the scroll
button on the front panel.
Click the button, the LC D display will scroll the
measurements.
Keep pressing the button for 3 seconds, the meter
will enter set-up mode.

4. Communication
4.1 Pulse Output
The meter is equipped with 2 pulse outputs, which are fully isolated from
the inside circuit. That generates pulses i n proportion to the measured
energy. The pulse outputs are polarity dependent , passive transistor
output requiring an external voltage source for correct operation. For
this external voltage source, the voltage shall be 5-27V DC, and the
maximum input current shall be 27mA DC.
Please contact us for the detailed Modbus/M-Bus communicaon protocol.

This manual does not contain all of the safety measures for operation of the
equipment(module,devi ce),because special oper ating conditions,and loc al
code requirements or regulations may necessitate further measures.
However,it does contain inform ation which must be read for your personal
safety and to avoid material damages.This information is highlighted by a
war ning tri angle and is repres ented as follows, depending on the degree of
potential danger.
This means that failure to observe the instruction can result in death,
serious injury or considerable material damage.
Thi s means hazard of electr ic shock and failure to take the
necessary safety precautions will result in death,serious injury or
considerable material dam age.
Operation of the equipment (module, device) described in this manual may
only be performed by qual ified pers onnel . Qualifi ed personnel in this manual
means person who ar e authorized to commission, start up, ground and label
devices,systems and circuits according to safety
and Regulatory standards.
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.
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 connect the meter to a 3 phase - 400VAC - network.
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.
