Purpose of Seminar:

How often do you get a chance to work with the Uninterruptible Power Supply system in your facility? Do you know what steps to take in the event of an emergency so that your facility can be kept up and running? What is your procedure if something goes wrong? What about regular testing and preventive maintenance?

Too often UPS systems come online late or delayed because the first responders aren't properly prepared. First responders are the people who will actually be at your facility when an outage occurs – the plant electrician, maintenance technician or a supervising engineer. This course is designed for them or anyone at your facility who needs a basic understanding of the application, installation, operation and troubleshooting of UPS systems and storage batteries. The theory of operation and the routine testing, troubleshooting and maintenance of typical single phase and three phase uninterruptible power systems are thoroughly covered, as are the safety precautions to be observed when working with these systems.

Backup emergency systems are essential, but only valuable if you have the people on staff trained to work with them in emergency situations. This class is designed to make sure your plant and facility personnel are ready for anything.

Who should take this course?

This course is created specifically for maintenance personnel who are "first responders" in industrial plants, public facilities, and commercial buildings. Attendees come from a wide variety of industries, skill-levels, company sizes, and job titles, so if you're not sure you'll fit in or benefit from this class, don't worry - you will! - as long as you have an interest in or responsibility for the UPS systems in your facility.
