Technical Data
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 regul at ions may necessitate further
measures. However,it does contain inform at ion whi ch must be read
for your personal safety and to avoid material damages.This information
is highlig ht ed by a warn in g tri an gle and is rep resente d as fo ll ows,
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 o f ele ct ric sho ck an d failure to tak e the
necessary safety precautions will result in death,serious injury
or considerable material damage.
Qualied personnel
Operation of the equipment (module, device) described in this manual
may only be performed by qualied personnel. Qualied personnel in
thi s manua l means p erson w ho 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
specied in the catalogue and the user manual,and only be connected
with devices and components recommended and approved by SIA
"Pawbol Baltic".
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
qualied personnel.
Never break the seals and open the front cover as this might inuence
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 ES3100D-Mod is digital three phase 4 wire energy meter with a
white back-lighted LCD screen for perfect reading. The unit measures
and displays active energy (kWh) and power ( W), imported and
exported. A resettable partial energy is provided, so the user can easily
check the import energy and export energy during a certain period.
Rs485 Output for Modbus RTU
The meter provides a RS485 port for remote communication. Modbus
RTU is the protocol applied. For Modbus RTU, the following RS485
communication parameters can be congured from the Set-up menu:
Baud rate 1200,2400, 4800, 9600
Parity none (default)/odd/even
Stop bits 1 or 2
RS485 network address nnn – 3-digit number, 001 to 247
Modbus™ Word order Hi/Lo byte order is set automatically to
normal or reverse. It cannot be congured from the set-up menu.
