UPS Startup/Commissioning

Many UPS models require a start-up to be performed by UPS manufacturer-trained personnel to ensure that they’re properly installed and calibrated. Manufacturer-trained field technicians can provide an overview of the equipment and a tutorial of how to operate the UPS. In addition to the start-up, the installation of the electrical equipment required for the UPS can be dangerous, and difficult. Hiring a third party service organization to assist with or supervise the UPS installation can help alleviate any problems that may occur. 

After the startup, the operational functionality of the UPS is verified through commissioning. The following tests/inspections are performed during UPS commissioning:

  • Component inspection/test
  • Installation inspection/test
  • Wiring visual inspection and verification
  • Tightness of bolted connections 
  • Energize and test system
    • Load burn-in
    • Transfers to/from Bypass
    • Power source trip test
    • Battery discharge test
  • Battery voltage checks

Generator Startup/Commissioning 

After a generator is installed, it must be inspected to ensure that all components are properly installed and working up to manufacturer specification standards. The operational safety of the generator is also checked during commissioning. 

Startup checklist includes inspections of: 

  • Safety and installation
  • Cooling system 
  • Gas/diesel system
  • Day tank 
  • Lubrication system
  • Starting system 
  • Exhaust system

Generator commissioning includes: 

  • Start and warm up period (No Load)
  • Warm up period (Add Load)
  • Generator set load test
  • Load bank test
  • Complete automatic restart period
  • Engine/generator operational test
