    how an inverter in a variable-torque application can conserve energy, and how an inverter drive can be used for soft-starting ? Describe environmental conditions that adversely affect inverter drivers and describe safety precautions for working with drives ? Give examples of error messages associated with electrical or motor problems ? Describe

    a drive overtemperature fault.

Electrical Safety Library (2 CD’s)

    2-4 hours of training

    This comprehensive interactive multimedia-training program consists of two individual lesson CD's that trains participants to understand the principles of basic electrical safety.

    Audience: This program is excellent for training every employee in all disciplines in basic electrical safety awareness.

Electrical Safety (A9701)

    Prerequisites: This lesson is designed so that no prior knowledge is required.

    Description: This lesson covers basic electrical safety practices based on the OSHA standards stated in 29CFR 1910 requiring qualification for work on live circuits. The lesson provides an understanding of electricity focused on increased awareness and prevention of industrial accidents.

    Objectives: Describe how voltage, current, and resistance are related and the effects various amounts of current have on the human body ? Identify the factors that influence body resistance to electric shock ? Describe how the

    amount of time spent in contact with an electrical circuit will affect the severity of shock ? List basic safety rules

    when working around electricity ? Describe the safe loading of circuits ? Identify safety considerations when using

    an extension cord and the proper procedure for inspecting portable electric hand tools ? Define the purpose of a

    ground fault interrupter (gfi) ? Identify the correct type of fire extinguisher to use on an electrical fire ? Identify

    requirements necessary to be a "qualified" person as defined by osha's 29cfr 1910 ? Describe the need to lock and

    tag a de-energized circuit before working on the circuit ? Describe the dangers of static electricity ? And describe

    the proper procedure for operating mobile equipment around energized circuits.
