14. Abnormal Operating Testing / 非正常工作测试

Damage to the inverter must not occur such as
fire, high temperature, breakdown, and molten metal etc, in equipment. 非正常工作条件下，不可出现起火、高温、击穿、出现熔出金属等现象。

15. Notice / 注意事项

A. Do not attach a conducting tape to lamp connecting wire, if the lamp
    wire attach to conductive tape, TFT-LCD module have a low luminance and the
    inverter has abnormal action because leakage current occurs between lamp
    wire and conducting tape. If the display arrangement is less friendly such
    as the asymmetrical wiring forces unequal losses and the lamps receive
    imbalanced current. Even with identical lamps, illumination may not be
    balance.

请勿试图在灯管的连接线上连接导线等物品，这样可能会造成灯管的电流不平衡，TFT-LCD模组的亮度会变暗，对相同的灯管，亮度也会产生不平衡现象。本产品也可能由于灯管的连接线上连接了类似导线等物品产生漏电流，而造成其它非正常动作。

B. For
    Safety Issue, please keep 4.0mm at least from the metal parts of the system
    to the inverter. or put a suitableinsulator
    between the inverter and the metal parts to avoid the situation of breakdown or arcingetc.

基于安全问题,请在组装本产品时,确保本产品和整机中的金属材料间保持至少4mm以上的距离, 或者使用足够绝缘等级的绝缘材料进行隔离, 避免高压放电而产生危险。

C. Don’t
twist , deform , drop or knock the inverter during assembly.

请在组装本产品时,避免扭曲,弯折,大力碰撞及跌落产生损害。

D.
    Guarantee to offer ESD shield bag to
    protect the product from electrostatic or magnetic interference during
    delivery. Due to the
    inverter is usually designed without the enclosure. please
    take care about ESD at anytime .

在产品交付的整个过程中均保证采用ESD屏蔽袋包装处理,因为该产品无外壳保护, 请务必随时注意防静电措施。

E.     China Galaxy products are not intended
    for use in systems in which failures of product could result in personal
    injury.

请勿将本产品使用在非适用范围的产品上，以免造成意外伤害。
