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 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 qualified personnel.
- Never break the seals and open the front cover as this might infiuence 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 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.
ES3100D-Mod supports max.100A direct connection, saves the cost and avoid the
trouble to connect external CTs, giving the unit a costeffective and easy
operation. Built-in interfaces provides pulse and RS485 Modbus RTU outputs.
Configuration is password protected.

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 configured
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 configured from the set-up menu.
Note:For Modbus protocol, please contact sales SIA “Pawbol Baltic”
