Make sure that the drive cabinet is attached to the floor to prevent it from toppling
over. The cabinet has a high center of gravity. When you pull out heavy components
or power modules, there is a risk of overturning.

the inlet and outlet drain valves. This will drain all modules in the cubicle.
6. After the cubicle has drained, disconnect the piping from the module.

centimeters. Keep the lifting chain tight.
