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