安全注意事项
在安装、运行、保养和维修前必须熟读使用说明书，以保证正确使用
。
使用说明书中对安全注意事项区分为“警告”
、
“注意”两个等级
。
：
不解除的话, 有可能造成死亡或重伤的危险状态
。
：
不解除的话, 有可能造成中等程度的残疾, 轻伤以及发生物质损伤事故
。
并且，即使在
,
中记载的事项根据情况也有可能导致发生重大事故，所以记载内容
都很重要，请必须遵守
。
1.
解开包装
(1)
请确认产品型号、适用容量与要求的规格是否一致
。
(2)
请检查是否有由于运输等原因而引起的零部件松动或破损现象
。
2.
保管
请避免高温多湿、有腐蚀性气体及日光直射的场所，以原包装的状态进行保管
。
3.
安装
(1)
请安装于干燥、洁净、牢固的场所。
(2)
请垂直安装。允许倾斜角度在 30°以内。(Fig.1)
(3)
可与热继电器组合的交流接触器、独立安装单元的型号请参照 Table1
。
4.
安装空间
安装间隙需在 Table 2 尺寸以上
（Fig.2 是 CJR3-50 与 FSZ-HD 组合的场合）
5.
接线
可以连接的电线尺寸及紧固力矩
请参照 Table 3。
6.
使用方法
(1)
在刻度范围内转动电流整定刻度盘，与▼标志对齐的电流值即为电动机全负载电流。
（Fig.3）在刻度范围外使用的场合，不能满足性能。
(2)
拉起测试按钮可进行顺序检查。而且，如果按测试按钮，b 触头(95－96)会分断，放开的
话就再次闭合。
（Fig.3）
(3)
在热过载继电器动作时，脱扣指示窗显示黄色。如需复位按复位按钮，脱扣指示窗黄色标
记隐藏。(在自动复位的状态，即使动作，脱扣指示窗也不会显示出黄色。)（Fig.3）
(4)
在热过载继电器动作时，必须排除过载等因素之后，轻轻按复位按钮进行复位。(此时，
当热过载继电器还未完全冷却时，复位无效。)
Safety Precautions
To ensure proper use of the product, be sure to read this manual and the other
attached documents carefully before starting installation, operation, maintenance
and inspection. Within this instruction manual, safety precautions are ranked, in
order of importance, as either “Warning” or “Caution”.
Indicates a potentially hazardous situation, which, if not avoided,
could result in death or serious injury.
Indicates a potentially hazardous situation, which, if not avoided, may
result in minor or moderate injury and/or damage to the equipment.
Under certain conditions, improper operation may result in serious injury and/or
damage even if it is labeled only as “Caution”. Every item indicated by either
“Warning” or “Caution” should be considered significant. Be sure to give particular
care to those items.
1. Unpacking
(1)
Check that the type and rating match the requested specifications.
(2)
Make sure that no parts have been lost or damaged.
2. Storage
Store the unit in the packing box. Do not store the packing box in a location
subject to high temperature, high humidity, corrosive gas, or direct sunlight.
3. Mounting
(1)
Mount in a dry, clean and stable location.
(2)
Mounting on a vertical surface. The product must not incline more than 30゜. (Fig.1)
(3)
See the Table 1 combination of contactor and thermal overload relay (TOR).
4. Mounting space
Mount the products at a distance of at least that shown in the Table 2.
（Fig. 2 ex. Combination of type CJR3-50and FSZ-HD）
5. Connection
Connectable wire size and proper tightening torque
See Table 3.
6. Usage
(1)
Turn the current setting dial within the scale so that the full load current of the
motor is at the ▼ mark (Fig.3). Do not use beyond the scale, or the expected
performance cannot be obtained.
(2)
By pulling the test button, checking of control circuit wiring can be done.
If it is depressed only the NC contact (95-96) is opened. If it is released, the NC
contact is closed again. (Fig.3)
(3)
When the TOR operates, the trip indicator displays a yellow sign. If the TOR is
reset, indication disappears from the indicator. (Even if the TOR operates, the
yellow sign dose not show in the trip indicator at automatic reset mode.) (Fig.3)
(4)
If the TOR operates, first remove the cause of failure such as overload, and then
lightly press the reset button to reset it. (In this case, the TOR cannot reset, if it is
not cooled sufficiently.)
