Why UPS System Training Matters
A UPS is often the last line of defence between a power disturbance and a critical load. Many UPS failures are not caused by the UPS hardware itself. They come from incorrect sizing, poor generator coordination, improper grounding, unsafe bypass transfers, ignored alarms or neglected maintenance. A single dropped load can mean lost data, damaged equipment, interrupted processes or a safety incident.
Engineers, technicians and facility managers need to understand the complete UPS system, not just the cabinet. That means knowing how it interacts with generators, transfer switches, grounding systems and the loads it protects, and how to operate and maintain it without putting the critical load or themselves at risk.
Course Overview
This 12-hour instructor-led course is organized into 12 practical modules over two days.
Day One covers UPS technology and architecture:
- the power quality problems a UPS solves
- the codes and standards that govern UPS systems
- UPS types and IEC 62040-3 classifications
- the rectifiers, inverters, static switches and power electronics inside the UPS
- modern transformerless, modular and high-efficiency (ECO) designs
- redundancy configurations
- UPS sizing, with a worked example
Day Two applies that knowledge to real installations:
- batteries as part of the UPS system
- UPS and generator coordination
- grounding, bonding, protection and installation best practices
- static and maintenance bypass operation
- alarms and troubleshooting
- safety, commissioning, preventive maintenance and reliability
The course closes with a complete UPS system case study.
Batteries are covered from the system perspective: runtime, DC bus, charger interaction and technology selection. Detailed battery inspection, testing and maintenance are covered in the companion course, UPS Battery Testing and Maintenance. Together, the two courses form a complete 24-hour UPS and battery reliability program.
The course references current codes and standards, including NFPA 70E (2027), the 2026 NEC, the 2024 CE Code, NFPA 70B (2026), UL 1778, IEC 62040 and ANSI/NETA ATS-2025.
Learning Outcomes
Upon completion of this UPS System Training, participants will be able to:
- Compare standby, line-interactive, double-conversion, rotary, transformerless and modular UPS designs using IEC 62040-3 classifications
- Size a UPS and select the right redundancy configuration (N, N+1, 2N) for an application
- Coordinate a UPS with standby generators and transfer switches
- Recommend proper grounding, bonding and protective-device coordination for UPS installations
- Perform safe static bypass and maintenance bypass transfers without dropping the load
- Interpret UPS alarms and troubleshoot common rectifier, inverter and static switch failures
- Apply NFPA 70E safe work practices, and plan commissioning and preventive maintenance for UPS systems
