Environment
Windows Task Manager
Cause
In PME 7.2 and greater, scheduled tasks have been removed from the ION Database Manager and are now handled by the Windows Task Scheduler which invokes Windows PowerShell files to run the backup. The PowerShell file itself will need to be modified to change the number of backups.
Resolution
*Warning: Take backups of any files prior to modifying them. Ensure the backups are in a location that will not be overwritten (i.e. the Desktop).*
Navigate to the following directory < >\Power Monitoring Expert\config\cfg\DbScheduledTasks (may vary depending on the installation directory) and open the file "Backup.ps1" either with Windows PowerShell or Notepad and edit the code as shown below.
Original Code:
Modified Code:
Save the file to retain the changes.
The following video demonstrates how to perform this configuration.

什么是电气安全？
电气安全是指 处理和维护电力设备以防止意外事件的常规做法。正确识别和控制电气危险对于保护周围环境和电气设备使用者的安全至关重要。
五种电气危险指的是什么？
使用电的主要危害包括触电以及接触带电部件造成的灼伤。使用电气设备的工作人员可能面临遭受电弧（当电流从一个电路跳到另一个电路时）伤害的风险。楼宇的电气安全包括最大限度地降低因电气设备或装置故障引发火灾，甚至因不合适的电气设备引发爆炸的风险。还应注意静电引燃易燃蒸汽或粉尘的风险，例如在喷漆室中就可能发生这种情况。
