Record the installed configuration

Check at your site: Exact model, internal batteries, external cabinets and bypass access.

  • Send the full model and serial number with the input and output voltages from the nameplate.
  • Record the battery arrangement, battery age and available service history.

Prepare the inputs for installation planning

Measured load, required runtime, bypass and room access are inputs to the assessment. Equipment selection requires a site electrical review.

  • For replacement planning, include measured load, expected growth and required runtime.
  • Describe the bypass arrangement and room access before installation planning.
  • Identify the protected load, available shutdown period and who can approve switching.

Choose the work to assess

Maintenance concerns the installed system. Replacement planning reviews its existing configuration and the site’s requirements.
