When a UPS is not maintained

When a UPS is not maintained or maintained incorrectly; one is taking a very expensive risk with not only the UPS and Batteries but with the operation in general. Below is an example of what can happened with poor maintenance:

This was Father’s Day, Sunday, June 20, 2004. At 0400, we received a call from a customer in Memphis.  He  received an alarm on his 200 kVA UPS.  It was a “general alarm” which did not specify the exact problem.  He went back to sleep believing the alarm was not “important”. 

At 0900 the customer called again requesting I come to the site. Arriving at the scene, fire trucks were everywhere.

Below are pictures of the aftermath:

  • What caused the fire is unknown. However, a lot can be learned from this incident:
  • Unit was 6 years old and had never been serviced
  • Prior to the fire the customer hired a UPS technician to inspect and PM the machine and batteries. 
  • Technician installed batteries 2 weeks before the incident.
  • Technician advised the 70 dB noise which was measured by the company engineer several weeks prior,  was simply normal “wear and tear” as a result of aging.

This technician had attended the manufacturers service center for “Training.” He paid $3000.00 for a 5-day “training” class which did not include meals or motels. The “instructor” no on-hands experience with UPS! The training consisted of identifying the visible components inside the unit, the input/output feeds and how to start-up/shutdown,  transfer to static switch, to manual bypass. For the $3000.00, he was given  a “certificate” certifying he was a “trained” technician to make repairs to this unit!

To conclude:

Five days of training is not enough-especially if you have no electronic background.The technician was a 3rd party servicer. He only worked on a UPS as needed.  He was a heating and air technician by trade. Technician admitted that a 5-day training is simply not enough and did not have any more knowledge than he had before his training. 

Many of the manufacturers have these training classes set up as a profit center. Having hundreds of technician’s pay a $3000.00 fee; it can provide an astronomical amount of revenue. The manufacturer benefits from a large pool of  3rd parties scattered throughout the country. Usually the manufacturer will dispatch a tech to a site based on the distance from the tech’s location! Oftentimes it is much less expensive than sending a “factory-man” who works for the manufacturer. 

Excellent service is as important as the UPS. Obtain qualified servicers – preferably those that are employees of the Company manufacturing the UPS’ – not a “5-day” tech. Certain manufacturers have full time and factory trained techs who  service technicians that work for the manufacturer. These folks are excellent and they will never think of a 70 dB noise to be normal due to aging!
