危险
注意
►切勿在有起火、爆炸危险的环境中使用，以免引发火灾、爆炸的危险。
►切勿私自改造、拆卸该产品。否则会导致产品故障、引发火灾或造成产品损
坏等事故。
►请勿将该产品安装在有灰尘、油烟、异性尘埃、腐蚀性气体、可燃性气体的
场所，勿使其暴露于高温、结露、风雨等恶裂环境中,勿将其安装在易受振动
冲击的场所。否则会损坏产品，导致其误动作或恶化。
►本产品报废时，请将其作为工业废弃物进行处理。
危险
注意
►请务必使用满足电流容量的电线。
►紧急停止电路请务必直接安置在外部,切勿使其通过张力控制器。
►机械的停止电路请务必直接设置在外部,切勿使其通过张力控制器 ，否则当
张力控制器误动作时，会使机械失控而引发事故。
►配线时请务必使用满足电流容量的电线，若电线过细，则会使绝缘包皮熔化
而导致绝缘不良，还可能引发触电、漏电及火灾等。
注意
►在打开控制器准备安装和接线之前要断开控制器外部所有电源至少要5分钟,
否则将导致触电或损坏产品。
►请务必在产品的接地端子上使用2mm2以上的电线进行接地（接地电阴100Ω或
更小）,否则将导致触电。
►请务必将强电电线与弱电电线分开配线，并勿将其共同接地。否则将会使弱
电线上的噪音叠加，导致误动作。
►切勿让铁屑或零碎电线落入产品中，否则会导致产品损坏、冒烟、起火、误
动作等危险。
■试运行
注意 ►请勿用湿手进行开关各 键 的 动 作 ， 否 同会导致触电。
►在通电和运行中请确认盖子已拧紧，否则会触电危险。
►在使用前，要除去所有覆盖物，以防止装置过热。

Cautions on Safety
(Make sure to read this page before using the unit.)
In this manual, cautions of safety are classified into "DANGER"
and "CAUTION". Even an item is classified as "CAUTION", its contents are
important and it may lead to a serious result depending on the
situation. Make sure to observe every item.
Danger:
Caution:
When the unit is handled incorrectly, a
dangerous situation may occur and the
possibility of death or serious injury is
expected.
When the unit is handled incorrectly, a
dangerous situation may occur and the
possibility of medium or slight injury is
expected or property damage exclusively
is expected.
Never use the unit in an atmosphere where
inflammation or explosion can occur.
Danger
Otherwise, inflammation or explosion may occur.
Set up the emergency stop circuit
independently of the product.
Otherwise, the unit may become out of order and an
accident may occur when malfunction occurs in the
tension controller. Make sure to assemble the
emergency stop circuit outside the tension controller.
Danger
Do not use any unused terminals for any
external lines.
Correctly connect the AC power cable to the specified
terminal, and do not use any unused terminals for any
external lines. Improper connection may seriously
damage the product.
Caution
Never touch a switch with a wet hand.
Danger
Never touch a switch with a wet hand, otherwise,
electrical shock may occur.
Never drop cutting chips and wire chips
while screw holes are tapped and wiring
work is performed.
Damage, fume, fire, malfunction or others may be
caused in the unit.
Danger
Confirm the ambient enviroments.
Never install the unit with an enviroment where dusts, soot,
conductive dusts or corrosive gas is present or a place
exposed to high temperature, condensation or wind and
rain. Otherwise, the unit may be damaged, malfunction or
be deteriorated.
Caution
Never open the covers while the power is
supplied to the unit or when the unit is
operating.
Never supply the power to the unit nor operate the unit
while the main body cover and the terminal cover are
open. When the covers are open, a high voltage area
may be exposed and electrical shock may occur.
Danger
Turn off all the phases of the external power
supply before starting installation and wiring.
Danger
Otherwise, electrical shock or damage in the unit may
occur. Make sure to turn off all the phases of the
external power supply before starting installation and
wiring.
Separate the wiring of the strong electric
system from the wiring of the weak electric
system.
Caution
Separate the wiring of the strong electric system from the
wiring of the weak electric system, and make sure that
noises are not superimposed on the wiring of the weak
electric system. Otherwise, the unit may not operate
correctly.
Danger
Never modify nor disassemble the unit
Never modify nor disassemble the unit. Otherwise, the
unit may become defective or an accident such as fire,
damage, etc. may occur.
Danger
Design the installation plan using the wire
size suitable to the current capacity.
Use the wire size suitable to the current capacity to
supply the power to the load. If a wire having smaller
current capacity is used,the insulation sheath will be
melted and insulation will become defective. In this
situation, electrical shock or a short-circuit may occur,
and fire may occur.
To assure safety
>Make sure the user thoroughly read this instruction manual
before using the unit, and pay attention in assuring safety
while using the unit.
>The unit is manufactured under the severe quality control.
When a severe accident or loss is expected in the
equipment used due to failure of the unit, provide a backup
function or the fail-safe function in the system.
Perform grounding ( grounding registance
100
Ω
or less).
Danger
Otherwise, electrical shock may occur. Perform
grounding ( grounding registance 100
Ω
or less) to the
unit using a wire of 2 mm
2
or more, otherwise, electrical
shock may occur. Never share the grounding with a
strong electric system.
