may possibly occur.
Make sure that the originator and target have the proper
configuration if you want to set the Open type as "Open only".
Required safety functions will be lost, and death due to injury
may possibly occur.
In debugging safety I/O terminals, check that the safety I/O
terminals and the external devices operate properly as
programmed by the CPU Unit which is an originator device.
Death due to injury may possibly occur.
Before you start the system, perform user testing to make sure
that the configuration data of all devices are correct and they
operate correctly.
Required safety functions will be lost, and death due to injury
may possibly occur.
Do not disassemble, repair, or modify the product.
Death due to injury may possibly occur.
Take appropriate and sufficient countermeasures when installing
the product in the following locations.
a) Locations subject to strong, high-frequency noise
b) Locations subject to static electricity or other forms of noise
c) Locations subject to strong electromagnetic fields
d) Locations subject to possible exposure to radioactivity
e) Locations close to power lines
CAUTION
Fire or malfunction may possibly occur if screws loosen.
Tighten terminal block fixing screws to the torques specified in
the reference manual.
Moderate burn injury may possibly occur. Do not touch any device
when power is being supplied or immediately after the power
supply is turned OFF.
Precautions for Safe Use
■Transporting/Installation/Wiring
• Do not drop any product or subject it to abnormal vibration or shock. Doing so may
result in injury, product malfunction or burning.
• Do not operate or store the product in the following locations. Doing so may result in
burning, in operation stopping, or in malfunction.
a) Locations subject to direct sunlight
b) Locations subject to temperatures or humidity outside the range specified in the
specifications
c) Locations subject to condensation as the result of severe changes in
temperature
d) Locations subject to corrosive or flammable gases
e) Locations subject to dust (especially iron dust) or salts
f) Locations subject to exposure to water, oil, or chemicals
g) Locations subject to shock or vibration
h) Locations subject to noise due to static electricity
• This is a Class A product (for industrial environments). In a residential environment,
it may cause radio interference. If radio interference occurs, the user may be
required to take appropriate measures.
• Use the GI-S Series in the enclosure complying with IP54 (IEC/EN 60529) or higher.
• In installing to the control panel, use DIN Tracks (TH35-7.5/TH35-15: IEC60715). In
order to prevent drops due to vibration, fix the GI-S Series to the DIN Tracks using
End Plates (sold separately).
• Install the product in a well-ventilated area. Avoid installing the product near heating
elements. Doing so may result in malfunction, in operation stopping, or in burning.
• Follow the instructions in the reference manual to correctly perform installation and
wiring.
• Use the methods that are specified in the reference manual for wiring the terminal
blocks.
• When you install wiring, be sure to turn off the power beforehand. Otherwise, the
external devices connected with the GI-S Series may operate unexpectedly.
• Use the correct wire size, wiring parts and tools when you wire the system.
Otherwise, cables may be disconnected to cause short-circuit or wire breakage.
• Make sure that the current capacity of the wire is sufficient. Otherwise, excessive
heat may be generated. When cross-wiring terminals, the total current for all the
terminals will flow in the wire. When wiring cross-overs, make sure that the current
capacity of each of the wires is not exceeded.
• Make sure that foreign material or metal dust should not come into the Safety I/O
Terminal while wiring and/or installation. Doing so may result in product burning,
electric shock, or failure.
• When you insert a flat-blade screwdriver into a release hole on the screwless
clamping terminal block, press the screwdriver down with an appropriate angle and a
force of 30 N or less. Applying excessive force may damage the terminal block.
• Do not tilt or twist the flat-blade screwdriver while it is pressed into the release hole
of the screwless clamping terminal block. Doing so may break the terminal block.
• Do not pull on the cables or bend the cables beyond their natural limit. Do not place
any heavy objects on the cables or other wiring lines. Doing so may severe the
cables.
• Mount terminal blocks and connectors only after checking the mounting location
carefully. During this time, be careful not to pinch your fingers.
• Be sure that the terminal blocks and Ethernet communications cables with tightening
screws or locking devices are properly tightened to or locked into place.
• DC power supplies must meet the following items:
a) Use reinforced insulation or double insulation.
b) Ensure an output hold time of 20 ms min.
c) Use an SELV power supply that meets the requirements of IEC/EN 60950-1 and
EN 50178.
• Select a unit power and output power supply with sufficient capacity by considering
the power supply capacity or inrush current when the power is turned ON that is
specified in the reference manual. Otherwise, the external power supply may not be
turned ON or malfunction due to unstable power supply voltage.
• Use the unit power supply and output power supply within the operating power
supply voltage range specified on the reference manual.
• Do not apply voltages that exceed the rated value or connect loads to the GI-S
Series Terminals.
• Surge current occurs when the power supply is turned ON. When selecting fuses or
breakers for external circuits, consider the fusing and sensing characteristics to
select fuses or breakers with appropriate specification. Refer to the reference manual
for surge current specifications.
■Operation/Maintenance
• Always turn OFF the power supply to the Safety I/O Terminal before you attempt any
of the following.
1) Assembling the Units
2) Setting rotary switches
3) Connecting cables or wiring the system
4) Connecting or disconnecting the terminal blocks or connectors
5) Attaching or removing the memory cassette
The V0 indicator for the controller remains lit for several seconds after power is
turned off. Make sure that the V0 indicator is not lit before you perform any of the
above operations.
• Avoid applying excessive force when you change the rotary switch settings.
• Insert the memory cassette all the way. And also, do not remove the memory
cassette while the power is being supplied. Data may become corrupted, and the
product will not operate correctly if it uses corrupted data.
• Always confirm safety before you transfer data or setting values from the Sysmac
Studio. During transfer, do not disconnect the cable or turn OFF the power supply to
the Safety I/O Terminal.
• If EtherNet/IP tag data links (cyclic communications) are used with a repeating hub,
the communications load on the network will increase. This will increase collisions
and may prevent stable communications. Do not use repeating hubs on networks
where tag data links are used. Use an Ethernet switch instead.
• Make sure to use the communications distance and method of connection for
EtherNet/IP within specifications. Do not connect EtherNet/IP communications to
Ether-CAT or other networks. An overload may cause the network to fail or
malfunction.
■Disposal
Dispose of the product in accordance with the relevant rules and regulations of the
country or area where the product is used.
