MAINTENANCE PROGRAM
In order to ensure continued reliable and safe
operation of the equipment, a program of
periodic maintenance must be established.
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.
NOTE:
Refer to the SAFETY section of this
manual for important information.
