[DESIGN PRECAUTIONS]
[DESIGN PRECAUTIONS]
WARNING
●Make sure to set up the following safety circuits outside the tension controller to ensure safe system
operation even during external power supply problems or tension controller failure. Otherwise,
malfunctions may cause serious accidents.
- Note that when an error occurs in a relay or transistor of an output circuit, the output might stay on
or off. For output signals that may lead to serious accidents, external circuits and mechanisms
should be designed to ensure safe machinery operation in such a case.
●Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock
circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to
prevent damage to the equipment at the upper and lower torque limits and upper and lower tension
limits).
●In an output circuit, when a load current exceeding the current rating or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
●For the operating status of each station after a communication failure of the network, refer to relevant
manuals for the network. Incorrect output or malfunction may result in an accident.
CAUTION
●If a power failure or an abnormal voltage drop occurs, the tension controller stops, and output is
turned off.
WARNING Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.

●Make sure to cut off all phases of the power supply externally before attempting installation or wiring
work. Failure to do so may cause electric shock or damage to the product.
●Use the product within the generic environment specifications described in LE7-40GU APPLICATION
MANUAL (SH-081822ENG). Never use the product in areas with excessive dust, oily smoke,
conductive dusts, corrosive gas (salt air, Cl2, H2S, SO2or NO2), flammable gas, vibration or impacts,
or expose it to high temperature, condensation, or rain and wind. If the product is used in such
conditions, electric shock, fire, malfunctions, deterioration or damage may occur.
CAUTION
●Do not touch the conductive parts of the product directly. Doing so may cause device failures or
malfunctions.
●Always wear an anti-static wristband and discharge static electricity from the body before handling the
extension option. Failure to do so may cause the extension option to fail or malfunction.
●When drilling screw holes or wiring, make sure that cutting and wiring debris do not enter the
ventilation slits of the tension controller. Failure to do so may cause fire, equipment failures or
malfunctions.
●Install the product on a flat surface. If the mounting surface is rough, undue force will be applied to the
PC board, thereby causing nonconformities.
●Install the product securely using mounting screws or fixtures.
●Connect the extension options securely to their designated connectors. Loose connections may
cause malfunctions.
●Make sure to affix the extension option with tapping screws. Tightening torque should follow the
specifications in the manual. If the screws are tightened outside of the specified torque range, poor
connections may cause malfunctions.
●Work carefully when using a screwdriver such as installation of the product. Failure to do so may
cause damage to the product or accidents.
●Connect the input/output cables and power cable securely to their designated connectors. Loose
connections may cause malfunctions.

●Make sure to cut off all phases of the power supply externally before attempting installation or wiring
work. Failure to do so may cause electric shock or damage to the product.
●Make sure to properly wire to the terminal block (Spring clamp type) in accordance with the following
precautions. Failure to do so may cause electric shock, equipment failures, a short-circuit, wire
breakage, malfunctions, or damage to the product.
- The disposal size of the cable end should follow the dimensions described in the manual.
- Twist the ends of stranded wires and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires of unspecified size.
- Affix the electric wires so that neither the terminal block nor the connected parts are directly
stressed.
CAUTION
●Perform class D grounding (grounding resistance: 100 or less) of the grounding terminal on the
tension controller with a wire 0.2 to 1.5 mm2. Do not use common grounding with heavy electrical
systems.
●Connect the power supply wiring to the dedicated terminals described in this manual. If an AC power
supply is connected to a DC input/output terminal or DC power supply terminal, the tension controller
will burn out.
●Do not wire vacant terminals externally. Doing so may damage the product.
●Install module so that excessive force will not be applied to terminal blocks, power wire, or
communication cables. Failure to do so may result in wire damage/breakage or tension controller
failure.
●Make sure to observe the following precautions in order to prevent any damage to the machinery or
accidents due to malfunction of the tension controller due to the effects of noise.
- Do not bundle the power line and communication cables together with or lay them close to the
main circuit, high-voltage line, load line or power line. As a guideline, lay the power line, control
line and communication cables at least 100 mm away from the main circuit, high-voltage line, load
line or power line.
- Ground the shield of the shielded wire or shielded cable at one point on the tension controller.
However, do not use common grounding with heavy electrical systems.
- Ground the shield of the analog input/output cable at one point on the signal receiving side.
However, do not use common grounding with heavy electrical systems.
WARNING
●Do not touch any terminal while the tension controller's power is on. Doing so may cause electric
shock or malfunctions.

3CC-LINK IE FIELD NETWORK BASIC
COMMUNICATION
Since LE7-40GU supports the slave function of CC-Link IE Field Network Basic communication which is an open FA network,
it can communicate with various CC-Link IE field network Basic master stations.
Precautions
• Since CC-Link IE Field Network Basic uses port No. [61451] as a device detection port, when port No. [61451] is used for
another communication function, CC-Link IE Field Network Basic connection cannot be used.
• Since LE7-40GU handles a number of object functions besides the CC-Link IE Field Network Basic connection function,
the response performance with respect to access from the master station may deteriorate. In such a case, it is necessary to
adjust the link scan time or the timeout time on the master station side. The recommended setting value is 50 ms or more.
