Summary for safety
Definition of the precaution and warnings
Warnings
Wrong operation could result in minor or moderate
injury. If the worst happens, it may result in death,
serious injury and property damage.
Wrong operation may result in minor or moderate
injury and property damage.
Don’t disassemble and touch any unit while the power is
supplied. Doing so may result in electrical shock.
Don’t touch any of the terminals while the power is supplied.
Doing so may result in electrical shock.
Take a fail-safe countermeasures by the customer to secure
safety in case of an abnormal signal caused by broken signal
line and momentary power interruption. Not doing so may
result in serious accidents.
Pay careful attention to the polarities(+/-) when wiring the
DC power supply. A wrong connection may cause
malfunction of the system.
Take appropriate countermeasures such as installing external breakers to ensure
safety in case of short-circuiting in external wiring.
Mount the unit only after checking the terminal blocks and the connectors
completely.
Be sure that screws of the terminal blocks are tightened to the torque specified in
this manual.
Wire correctly.
Use the power supply voltage specified in this manuals.
Be particularly careful the place where the power supply is unstable to secure the
power with the rated voltage. Use CLASS2 power supply.
Do not allow wire clippings, shavings, or other foreign material to enter any Unit.
Otherwise, Unit burning, failure, or malfunction may occur. Cover the Units or take
other suitable countermeasures, especially during wiring work.
Do not allow foreign matter to enter the openings in the Unit. Doing so may result in
Unit burning, electric shock, or failure.
Be sure to ground when installing the unit.
Supply the power only after proper and sufficient checking of the wiring and switch.
Don’t attempt to disassemble, repair and modify this unit.
Don’t pull on the cables or bent them beyond its manual unit.
Don’t place objects on cables and codes.
Before touching the unit, be sure to first touch a grounded metallic object in order
to discharge any static built-up.
This unit is class A (Industry Environment product). A usage in living may result in
interruption of electric frequency. Take a proper countermeasure against the
interruption of electric frequency when its case.

LAN Cable
When using twist pair (STP) cable with a shield, it is expected to prevent a noise.
However, as the shield of the cable is installed in this unit, the both side of LAN
cable may be grounded. Attempt to ground its other side and use twist pair cable
(UTP) without shield when grounding its both side may lead ground electric
difference.
QoS Function
Qos can compare Implicit Message with other standard packet and transfer it by
priority.
The Implicit Message is I/O data for EIP controlling. Turn off Qos when
using it in normal mode, which has no function to put priority.
Priority when QoS is ON is the following.
