circuits. 
 
If any liquid is detected inside the equipment, immediately disconnect the power supply 
and contact the administrator. 
 
Do not expose the equipment to flammable or explosive gas or smoke. Do not perform 
any operation on the equipment in such environments. 
 
Ensure that the equipment room provides good heat insulation, and the walls and floor 
are dampproof.
