IEEE 499-1997

This recommended practice applies to all electric drives including motors, control, and control wiring associated with machinery or equipment commonly used in the manufacturing areas of cement plants. The recommendations made here are intended as a guide and may be supplemented where special needs exist. They are not intended to apply to power distribution circuits. These recommendations apply to electrical equipment having a supply voltage of 13 800 V or less. Voltages higher than this are not covered by this recommended practice. The purpose of this recommended practice is to define and recommend practice for electric drives and related electrical equipment for installation in the cement industry in order to promote the following: — Safety to personnel and equipment — Maximum reliability with minimum loss of production — Reduced maintenance and increased life of equipment — Clarification of needs and conditions to reduce special engineering and chance of error in specification — Overall economy Revision Standard - Inactive-Reserved. All electric drives, including motors and control wiring associated with machinery or equipment commonly used in the manufacturing areas of cement plants are covered. Recommendations are not intended to apply to power distribution circuits. These recommendations apply to electrical equipment having a supply voltage of 13 800 V or less.
