To prevent electric shock, turn off the power before starting 
maintenance and inspections. 
 
To prevent electric shock or other injury, check to make sure that 
the unit status indicators read OFF and DISCHARGED before 
beginning maintenance and  inspection work. 
 
To prevent electric shock, do not touch charged parts. 
 
Keep fingers and other body parts, objects, etc. away from the unit 
mechanism, as you may become caught in the mechanism and 
injured. 
 
To prevent electric shock or other injury, do not attempt to modify 
the lock mechanism on the disconnecting switch mounted on the 
unit power side. 
 
Hazardous voltage can cause serious injury or death. Make sure 
maintenance and inspection work is performed only by authorized 
personnel.
 
 
The VCB should be maintained and inspected periodically to maintain performance and 
ensure a long service life.
 
Operating and environmental conditions will usually dictate the 
frequency of inspection required. NFPA Publication 70B "Electrical Equipment Maintenance" 
may be used as a guide for setting up the maintenance program. 
 
Contact with energized components can cause severe injury, death and 
property damage. Turn off and lock-out primary and control circuit power 
before servicing.
 
 
Improper maintenance can cause severe injury, death and property damage.  
Only qualified and authorized persons are to install, operate or service this 
equipment. 
 
Grease is conductive. Do not allow grease or any other substances to 
contaminate insulating materials. Contaminated insulators can allow a short 
circuit or ground fault to occur.
