安全总结（续）
•测试和操作工艺时，工艺技术人员应在场
物体。
•如果存在任何不确定性，切勿激活任何系统初始化按钮
存在关于初始化期间系统内发生的确切信息。
总是先检查。
•始终记住，控制系统可以通过
远程工程站，通过控制连接到另一个节点
网络
•记住，AC 800M控制器将在电压
应用。
采取措施使流程处于安全状态，提高了
电源、通信链路或控制系统部件时的安全
失败例如，这些步骤可能需要安装阀门或继电器
自动返回故障安全位置。
产品安全
必须始终遵守以下安全规则：
•为避免释放静电，将自己和任何工具接地
在处理印刷电路板、电池、存储卡和其他
设备的敏感部件
•所有电子设备对ESD（静电放电）敏感。到
处理印刷电路板时避免意外损坏
建议佩戴腕带，接地至底盘。带子必须
具有内置保护电阻器
•储存和运输时必须使用防静电导电塑料袋
运输中的PC板。

Safety Summary (continued)
• Process technicians are to be present when testing and operating process
objects.
• Never activate any System Initialization push-button if any uncertainty
exists regarding exactly what occurs within the system during initialization.
ALWAYS CHECK FIRST.
• Remember at all times, that the control system can be controlled from a
remote engineering station, connected at another node via Control
Network.
• Remember, the AC 800M Controller will start automatically when voltage
is applied.
Taking steps to bring the process to a safe state, provides an improved level of
safety when power supplies, communication links or parts of the control system
fail. Such steps may require, for example, the installation of valves or relays that
automatically return to a fail-safe position.
Product Safety
The following safety rules must be observed at all times:
• To avoid discharging static electricity, ground both yourself and any tools
before handling printed circuit boards, batteries, memory cards, and other
sensitive pieces of the equipment
• All electronic devices are sensitive to ESD (electrostatic discharge). To
avoid accidental damage while handling printed circuit boards, it is
recommended to wear a wrist strap, grounded to the chassis. The strap must
have a built-in protective resistor
• Anti-static, conductive plastic bags must be used for storage and transport
of PC boards in transit.

Safety Summary
Before replacing Units
Maintenance
All procedures for replacing units can be located by referring to the relevant
documentation.
Removing or replacing units with system power connected can cause injury to
personnel and damage to equipment. It is, therefore, of the utmost importance
that the power supply be fully disconnected, on the process side, before removal
or insertion of units takes place.
See Online Replacement of Unit on page 198 and I/O documentation.
It is recommended that a stock of suitable spare components be maintained to
avoid system downtime.
Ensure that back-up copies of the current application program are made at
regular, predetermined intervals to avoid system downtime.
