在任何情况下都必须严格遵守本手册中的说明
不这样做可能会导致潜在危险源的产生，或使安全功能集成在手持终端中。
除本手册中给出的安全说明外，安全预防措施和事故还必须遵守适合有关情况的预防措施。
❑ 必须采取措施，以确保在功率下降或电源故障时，中断的程序可以正确重新启动。这样情况下，不得出现危险的操作条件即使是暂时的。
❑ 在自动化系统上发生故障的所有情况下造成人身伤害或机械和设备严重损坏，
必须采取额外的外部安全措施，以确保：系统作为一个整体，即使在故障事件。
❑ 安全相关部件的功能（急停和启用开关）必须定期测试。
❑ 此外，在设备受到强烈冲击（例如，设备坠落到地面）后必须测试安全相关部件的功能。
2.1电源该装置符合EN61131-2的安全等级III，并且EN50178.必须保证设备的24V电源
通过安全隔离低压电路和危险接触电压电路（例如通过安全变压器或类似设施）。

The instructions contained in this manual must be precisely followed in all circumstances.
Failure to do so could result in the creation of potential sources of danger or the disabling of
safety features integrated in the handheld terminal.
Apart from the safety instructions given in this manual, the safety precautions and accident
prevention measures appropriate to the situation in question must also be observed.
❑ Measures must be taken to ensure that in the event of power dips or
power failures, an interrupted program can be properly restarted. In such
situations, no dangerous operating conditions must be allowed to occur
even temporarily.
❑ In all situations where faults occurring on the automation system could
cause personal injury or significant damage to machinery and equipment,
additional external safety measures must be taken in order to ensure the
system as a whole remains in a safe operating condition even in the
event of a fault.
❑ The functionality of safety-related parts (E-stop and enabling switches)
must be tested regularly.
❑ Also after strong shocks (e.g. device falls to ground) of the device, the
functionality of safety-relevant parts must be tested.
2.1 Power Supply
The device meets the safety class III in accordance with EN61131-2 and
EN50178. The 24V power supply for the equipment must be guaranteed
through safe isolation of the low-voltage circuits from dangerous-contact
voltage circuits (e.g. by safety transformers or similar facilities).
