1. Important Notes
Solid state equipment has operational characteristics differing from those of electromechanical equipment.
Safety Guidelines for the Application, Installation and Maintenance of Solid-State Controls describes some
important differences between solid state equipment and hard-wired electromechanical devices.
Because of this difference, and because of the wide variety of uses for solid state equipment, all persons
responsible for applying this equipment must satisfy themselves that each intended application of this
equipment is acceptable.
In no event will HITACHI be responsible or liable for indirect or consequential damages resulting from the use
or application of this equipment. The examples and diagrams in this manual are included solely for illustrative
purposes. Because of the many variables and requirements associated with any installation, HITACHI cannot
assume responsibility or liability for actual use based on the examples and diagrams.
✓If you don't follow the directions, it could cause a personal injury, damage to the equipment or
explosion
⚫Do not assemble the products and wire with power applied to the system. Else it may cause an electric
arc, which can result into unexpected and potentially dangerous action by field devices. Arching is
explosion risk in hazardous locations. Be sure that the area is non-hazardous or remove system power
appropriately before assembling or wiring the modules.
⚫Do not touch any terminal blocks or IO modules when system is running. Else it may cause the unit to an
electric shock or malfunction.
⚫Keep away from the strange metallic materials not related to the unit and wiring works should be
controlled by the electric expert engineer. Else it may cause the unit to a fire, electric shock, or
malfunction.
✓If you disobey the instructions, there may be possibility of personal injury, damage to equipment
or explosion. Please follow below Instructions.
⚫Check the rated voltage and terminal array before wiring. Avoid the circumstances over 55℃of
temperature. Avoid placing it directly in the sunlight.
⚫Avoid the place under circumstances over 85% of humidity.
⚫Do not place Modules near by the inflammable material. Else it may cause a fire.
⚫Do not permit any vibration approaching it directly.
⚫Go through module specification carefully, ensure inputs, output connections are made with the
specifications. Use standard cables for wiring.
⚫Use Product under pollution degree 2 environment.
Warning!
Caution!

1.1.1. Symbols
Identifies information about practices or circumstances that can cause an explosion
in a hazardous environment, which may lead to personal injury or death property
damage or economic loss.
Identifies information that is critical for successful application and understanding of
the product.
Identifies information about practices or circumstances that can lead to personal
injury, property damage, or economic loss.
Attentions help you to identity a hazard, avoid a hazard, and recognize
the consequences.
1.1.2. Safety Notes
The modules are equipped with electronic components that may be destroyed by
electrostatic discharge. When handling the modules, ensure that the environment
(persons, workplace, and packing) is well grounded. Avoid touching conductive
components, e.g. G-BUS Pin.

5.2. Plugging and Removal of the Components.
As above figure to safeguard the RIO3 module from jamming, it should be fixed onto the DIN rail with locking
level. To do so, fold on the upper of the locking lever. To pull out the RIO3 module, unfold the locking lever.
Before work is done on the components, the voltage supply must be
turned off.

5.3. G-Bus Pin Description
Communication between the RIO3 series and the expansion module as well as system / field power supply of
the bus modules is carried out via the internal bus. It is comprised of 6 data pin and 2 field power
pins.
Do not touch data and field power pins to avoid soiling and damage by ESD noise.

6.1. G-Bus System
•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 SyncNet, PROFIBUS, CANopen, DeviceNet , Ethernet/IP, CC-Link,
MODBUS/Serial, MODBUS/TCP etc.
•Expansion Module
The Expansion Modules are supported a variety of input and output field devices.
There are digital and analog input/output modules and special function modules.
•Two types of RIO3 Bus Message
- Service Messaging
- I/O Messaging
