General Safety Requirements
WARNING
- Do not assemble the products and wires with power connected to the system. Doing so cause an “arc flash”, which can result in unexpected dangerous events (burns, fire, flying objects, blast pressure, sound blast, heat).
- Do not touch terminal blocks or IO modules when the system is running. Doing so may cause electric shock, short circuit or malfunction of the device.
- Never let external metallic objects touch the product when the system is running. Doing so may cause electric shock, short circuit or malfunction of the device.
- Do not place the product near inflammable material. Doing so may cause a fire.
- All wiring work should be performed by an electrical engineer.
- When handling the modules, ensure that all persons, the workplace and the packing are well grounded. Avoid touching conductive components, the modules contain electronic components that may be destroyed by electrostatic discharge.
CAUTION
- Never use the product in environments with temperature over 60℃. Avoid placing the product in direct sunlight.
- Never use the product in environments with over 90% humidity.
- Always use the product in environments with pollution degree 1 or 2.
- Use standard cables for wiring.
About the G-series System
System overview
- Network Adapter Module: The network adapter module forms the link between the field bus and the field devices with the expansion modules. The connection to different field bus systems can be established by each of the corresponding network adapter module, e.g., for MODBUS TCP, Ethernet IP, EtherCAT, PROFINET, CC-Link IE Field, PROFIBUS, CANopen, DeviceNet, CC-Link, MODBUS/Serial etc.
- Expansion Module: Expansion module types: Digital IO, Analog IO, and Special modules.
- Messaging: The system uses two types of messaging: Service messaging and IO messaging.
IO Process Data Mapping
An expansion module has three types of data: IO data, configuration parameter, and memory register. The data exchange between the network adapter and the expansion modules is made via IO process image data by internal protocol.
Data flow between network adapter (63 slots) and expansion modules
The input and output image data depend on the slot position and the data type of the expansion slot. The ordering of input and output process image data is based on the expansion slot position. Calculations for this arrangement are included in the manuals for network adapter and programmable IO modules.
Valid parameter data depends on the modules in use. For example, analog modules have settings of either 0-20 mA or 4-20 mA, and temperature modules have settings such as PT100, PT200, and PT500. The documentation for each module provides a description of the parameter data.

NOTE
- Set frequency to get the correct power factor and energy.
NOTE
- The reactive power measurement is negative when the load is capacitive, and when the load is inductive. The sign of the reactive power can therefore be used to reflect the sign of the power factor.
Power factor = (Sign fundamental reactive power) * (abs (Active power)) / Apparent power)
Example of setting
- Read data: Phase1 RMS Voltage / RMS Current / Apparent power / Active power.
- Input value: 220 V, 1000 A, PF 0.5.
- Parameter: CT 1: 1000, input frequency 55-65 Hz, overvoltage threshold 260 V, other is Default(0).
Overvoltage threshold = (260 V (user setting value) – 250 V (default setting value)) / 0.2 V. Resolution: 0.2 V.
Overcurrent threshold = 1000 A (user setting CT 1: 1000) = ((1 A (user setting value) – 0.8 (default setting value)) / 0.001) * 1000 (CT). Resolution: 0.001 A.
All of default value is 0.
- Set the Parameter.

Hardware Setup
CAUTION
- Always read this chapter before installing the module!
- Hot surface! The surface of the housing can become hot during operation. If the device is used in high ambient temperatures, always let the device cool down before touching it.
- Working on energized devices can damage the equipment! Always turn off the power supply before working on the device.
Space Requirements
The following drawings show the space requirements when installing the G-series modules. The spacing creates space for ventilation, and prevents conducted electromagnetic interference from influencing the operation. Installation position is valid vertical and horizontal. The drawings are illustrative and may be out of proportion.
CAUTION
NOT following the space requirements may result in damaging the product.
Mount Module to DIN Rail
The following chapters describe how to mount the module to the DIN rail.
CAUTION
The module must be fixed to the DIN rail with the locking levers.
Mount GL-9XXX or GT-XXXX Module
The following instructions apply to these module types:
- GL-9XXX
- GT-1XXX
- GT-2XXX
- GT-3XXX
- GT-4XXX
- GT-5XXX
- GT-7XXX
GN-9XXX modules have three locking levers, one at the bottom and two on the side. For mounting instructions, refer to Mount GN-9XXX Module.
Mount GN-9XXX Module
To mount or dismount a network adapter or programmable IO module with the product name GN-9XXX, for example GN-9251 or GN-9371, see the following instructions:
