Liebert EXM: service and replacement planning
Family reference
The EXM family has fixed and scalable configurations. Voltage variants have different power ranges and ancillary cabinets.
Selected North American 208 V and 480 V ranges. Fixed and scalable configurations exist; confirm the installed configuration.
Identify the voltage and construction variant
- Published capacity
- 10-200 kW (208 V); 50-250 kW (480 V)Source 1
Record the installed configuration
Check at your site: Voltage variant, installed capacity, maintenance bypass and distribution.
- 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.
