System Maintenance
7.1 Routine Maintenance
Before cleaning the system, connecting cables, and maintaining the grounding reliability,
power off the system to ensure that the SACU is de-energized and will not cause personal
injury.
If you need to open the cabinet door on rainy or snowy days, take protective measures to
prevent rain or snow from entering the cabinet. If it is impossible to take protective
measures, do not open the cabinet door on rainy or snowy days.
