1.1 Safety Precautions
WUME-SCHG1ETC-21-2
1.1 Safety Precautions Always observe
This section explains important rules that must be observed to prevent personal injury and prop-
erty damage.
■ The hazards that may occur if the product is used incorrectly are described and classied by
level of harm.
WARNING Risk of death or serious injury.
CAUTION Risk of minor injury or property damage.
WARNING
●Never use this product as a sensing device for personnel protection.
●For sensing devices for personal protection, use products that conform to the laws and standards
related to personal protection in each country, such as OSHA, ANSI, and IEC.

1.2 Handling Precautions
WUME-SCHG1ETC-2 1-3
1.2 Handling Precautions
■The following symbols are used to indicate safety information that must be observed.
Indicates an action that is prohibited.
Indicates an action that must be taken.
Indicates a matter that requires caution.
Information
Indicates supplemental information.
Reference Indicates reference to details about the subject in question.
Note Indicates points to be noted when the product is operated.
Specications
●This device has been developed / produced for industrial use only.
●This product uses an EEPROM. The EEPROM has a service life of one million setting opera-
tions.
● Do not use this product outside the range of the specications. Risk of an accident and prod-
uct damage.
There is also a risk of a noticeable reduction of service life.
Power supply
●Incorrect wiring damages the internal circuits, so check the wiring before turning ON the pow-
er.
● Verify that uctuations of power input supply voltage do not exceed the rating, including the
connected devices.
●Note that there is a risk of damage and burning if a voltage greater than the rated voltage is
applied or AC power is directly applied.
●If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.)
terminal is connected to an actual ground.
● Ensure that the power supply capacity is su󰀩cient.
●Do not use this product during the initial transient time immediately after the power supply is
switched ON.
●For DC power supply, always use an isolation transformer. If an autotransformer is used, the
main unit or power supply may become damaged.
●If surges occur in the power supply that is used, connect a surge absorber to the source of
the surge occurrence to absorb surges.

1.2 Handling Precautions
WUME-SCHG1ETC-21-4
Wiring
●Before wiring or connection work, always make sure that the power is OFF. Failure to do so
may result in electric shock or damage.
●When noise generating devices (such as switching regulators and inverter motors) are used
around this product, always ground the frame ground (F.G.) terminal of each device sepa-
rately.
●To avoid noise, make the wiring as short as possible.
●Do not wire the controller in parallel with a high-voltage line or power line or use the same
conduit as these lines. Doing so may result in malfunctioning due to induction.
●Use Ethernet cables compatible with EtherCAT.
●Do not apply stress such as excessive bending or pulling to the connector base of the Ether-
net cable. Doing so may result in malfunctioning due to damage or connection failure.
●Always ground the shield of the Ethernet cable on the master device side. This product does
not have a grounding terminal.
● For the detailed connection specications, refer to the EtherCAT Installation Guide published
by the EtherCAT Technology Group (ETG).
Operating environment
●This product is suitable for indoor use only.
●Avoid using the product in steamy or dusty locations or other similar locations.
●Avoid using the product in atmospheres that contain corrosive or other harmful gases.
●Ensure that the product does not come into contact with organic solvents such as thinner.
●Ensure that the product does not come into contact with strong acid or alkaline.
●Ensure that the product does not come into contact with oil or grease.
● This product cannot be used in an environment that contains ammable or explosive gases.
● Performance may not be satisfactory in a strong electromagnetic eld.
●Do not use this product in locations subject to severe vibration or shock.
●Do not drop the product or otherwise subject to shock. Doing so may result in failure.
●For details on how to use the PC to be connected, refer to the instruction manual provided
with the PC.
Other precautions
●Never attempt to disassemble, repair, or modify the product.
●When the product becomes unusable or unneeded, dispose the product appropriately as in-
dustrial waste.
●Design the system so that protection and safety circuits for protecting the system from prob-
lems are located outside.

Information
●If HG-SC series and HG-TC series controllers are used in combination, connect the slave con-
trollers of the same series as the master controller on the near side of the master controller and
connect the slave controllers of di󰀨erent series from the master controller on the far side of the
master controller.
Example: When the master controller is HG-SC□
Controller - Slave unit

●If HG-TC series and HG-SC series controllers are used in combination, there are limitations on
the functions below.
Item Description of limitation
1Calculation
function
Calculation is only performed when the slave unit is the same series as the
master unit.
Calculation is not performed when the slave unit series is di󰀨erent from the
master unit series. "CALC" does not appear in the display of a slave unit of a
di󰀨erent series.
2Input all
The master unit only performs input all when the slave units are the same
series.
A slave unit of a di󰀨erent series from the master unit does not perform input
even when the external input settings match those of the master unit.
3Copy function
Copying is only performed when the slave unit is the same series as the mas-
ter unit.
When copying is executed, "NOW COPY" appears even on the display of a
slave unit of a di󰀨erent series from the master unit , but copying is not per-
formed.
4Interference
prevention
This function is only available on the HG-TC series controller. The function is
not executed on the HG-SC series controller.
