“系统”或管理您特定位置的等效系统。
导电异物、灰尘或液体可能导致安全功能失效。
危险
接地不足引起触电
 验证是否符合所有当地和国家电气规范要求以及所有其他适用要求
有关整个驱动系统接地的规定。
 施加电压前，将驱动系统接地。
 不得将导管用作保护接地导体；在内部使用保护接地导体
管道
 保护接地导体的横截面必须符合适用标准。
 不要将电缆屏蔽层视为保护接地导体。
不遵守这些说明将导致死亡或重伤。
危险
触电或意外设备操作
 防止异物进入产品。
 验证密封件和电缆入口是否正确入位，以避免沉积物等污染
和湿度。
不遵守这些说明将导致死亡或重伤。
警告
失去控制
 任何控制方案的设计者必须考虑控制路径的潜在故障模式，以及，
对于某些关键控制功能，提供在路径期间和之后实现安全状态的方法
失败关键控制功能的示例包括紧急停机和超程停机、断电
然后重新启动。
 必须为关键控制功能提供单独或冗余的控制路径。
 系统控制路径可以包括通信链路。必须考虑
意外传输延迟或链路故障的影响。
 遵守所有事故预防规定和当地安全指南。1.
 必须对该设备的每个装置进行单独和彻底的测试，以确保其正常运行
投入使用前。
不遵守这些说明可能导致死亡、重伤或设备损坏。
警告
异物导致安全功能丧失
保护系统免受导电物质的污染。
不遵守这些说明可能导致死亡、重伤或设备损坏。

An engineering phase is mandatory prior to mechanical and electrical installation. See chapter Engineering (see page 57) for basic information. 1 For additional information, refer to NEMA ICS 1.1 (latest edition), “Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control” and to NEMA ICS 7.1 (latest edition), “Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems” or their equivalent governing your particular location. Conductive foreign objects, dust or liquids may cause safety functions to become inoperative. DANGER ELECTRIC SHOCK CAUSED BY INSUFFICIENT GROUNDING  Verify compliance with all local and national electrical code requirements as well as all other applicable regulations with respect to grounding of the entire drive system.  Ground the drive system before applying voltage.  Do not use conduits as protective ground conductors; use a protective ground conductor inside the conduit.  The cross section of the protective ground conductor must comply with the applicable standards.  Do not consider cable shields to be protective ground conductors. Failure to follow these instructions will result in death or serious injury. DANGER ELECTRIC SHOCK OR UNINTENDED EQUIPMENT OPERATION  Keep foreign objects from getting into the product.  Verify the correct seating of seals and cable entries in order to avoid contamination such as deposits and humidity. Failure to follow these instructions will result in death or serious injury. WARNING LOSS OF CONTROL  The designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop, power outage and restart.  Separate or redundant control paths must be provided for critical control functions.  System control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link.  Observe all accident prevention regulations and local safety guidelines.1  Each implementation of this equipment must be individually and thoroughly tested for proper operation before being placed into service. Failure to follow these instructions can result in death, serious injury, or equipment damage. WARNING LOSS OF SAFETY FUNCTION CAUSED BY FOREIGN OBJECTS Protect the system against contamination by conductive substances. Failure to follow these instructions can result in death, serious injury, or equipment damage.
