Hoisting Devices
Do not walk under hoisted objects.
Only trained and qualified personnel should perform hoisting operations.
Check that all hoisting tools are available and in good condition.
Before hoisting objects, ensure that hoisting tools are firmly fixed onto a load-bearing
object or wall.
Ensure that the angle formed by each hoisting cable is less than 90 degrees.
If metal hoisting cables are used, place protective pads between the cables and the
cabinet to prevent scratches to the cabinet surface.

Drilling Holes
Do not drill holes into a cabinet without permission. Incorrect drilling operations may affect
the electromagnetic shielding of the cabinet and damage cables inside. Metal shavings from
drilling may short-circuit boards inside the cabinet.
