     ●lntelligent electric meter             ●Composite power switch

■注意事项Matters needing attention

1、 磁保持继电器出厂状态为触点闭合状态(复位状态),但因运输或继电器安装时受到冲击等因素的影响,可能会改变状态,因此在使用前(电源接入时)有必要采取措施重新使其复位。

 Magnetic latching relay factory condition for contact closure state,but because carry or installed when subjected to impact,may change state,therefore before use to make its reset.

2、 为了确保磁保持继电器可靠动作,施加到线圈上的激励电压须达到额定值,且脉冲宽度设置须达到动作时间的3倍以上。

Ln order to ensure the reliability of relay coil voltage,must reaeh value,the pulse width must be 3 times more time.

3、 不带软铜编织线的磁保持继电器,负载引出脚不能锡焊,不能随意扳动,且不能同时刚性固定两个引出脚。

Not with braided line relay,the load pin can not solder,not arbitrarily wrenched,two pins and rigid fixation

4、磁保持继电器是有极性区分的,如果用户需要的极性与本资料不符,应在订货时特别提出。

Magnetic latching relay is polar differentiation,and if the user needs to polarity and the data is inconsistent,should be in order when the special offers.

5、继电器入厂检查及使用中应轻拿轻放,防止跌落影响参数。入厂作破坏性检查的产品要与正常产品严格区分标识,不得装机使用。

Relay incoming inspection should be light-light,do the destructive test of products must be consistent with normal goods isolated and labeled,shall not be used.
