A recommended practice for electric drives and related electrical equipment for installation in the cement industry is set forth. The recommendations apply to all electric drives and include motors, controls, and control wiring associated with machinery or equipment commonly used in the manufacturing areas of cement plants, but they do not apply to power distribution circuits. The intent is to promote safety for 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, and overall economy.

These recommendations apply to all electric drives and include motors, control, and control wiring associated with machinery or equipment commonly used in the manufacturing areas of cement plants. They 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 being covered at this time.

The purpose of these recommendations is to define and recommend practice for electric drives and related electrical equipment for installation in the cement industry in order to promote (1) Safety to personnel and equipment (2) Maximum reliability with minimum loss of production (3) Reduced maintenance and increased life of equipment (4) Clarification of needs and conditions to reduce special engineering and chance of error in specification (5) Overall economy.
