The GE Power Connection Board 531X121PCRAEG1 is a renewal part for multiple original equipment power connection boards. Anytime you must install, service or maintain the drive, you must have a qualified servicer perform the procedures. The drive is high energy device and the threat exists for serious electrical shock and burns. The servicer must also know that even when power is disconnected, that components store energy and the servicer must wait a few seconds before removing components to allow time for the electricity to exit the drive.
Another reason that only qualified servicers should work on the drive is the danger posed by the moving parts in the drive and other devices that might be in the general area. It is best practice to halt all activity in the surrounding area before repairs start. All boards are easy to replace and the drive features an easily accessed board cabinet with a drive carrier that enables quick release, removal, and installation of boards. This reduces the time the drive is offline and reduces the inconvenience and time other devices are offline also.
A grounding strap must be worn when you work on the board replacement. One end of the grounding strap is a clip that you attach to any unpainted metal surface. The other end is a strap that you wear on your wrist. The static electricity drains off you and the board and seeks ground and so prevents a static build up. The build up can damage the board.
