Mechanical Safety
l Before carrying a heavy object, use appropriate tools to protect yourself from bruise or
sprain.
l Before pulling the chassis out of the cabinet, check whether there are any unstable or
heavy objects on the cabinet. Be careful not to make the objects fall, which may cause
body injuries.
l Do not drill holes on a cabinet without permission. Unqualified holes on a cabinet affect
the electromagnetic filter performance of the cabinet and cause damages to the cables in
the cabinet. In addition, metal scraps may fall into the cabinet when you are drilling holes,
causing short circuit on printed circuit boards (PCBs).
3.2 Checking Installation Environment
