Top UPS design considerations

There are some important things consider when designing an uninterruptible power supply system (UPS). Our experts have created a list of things to consider when tackling the job. Remember Eaton is here to help. Use our resources or contact us. We can help you make the right decision.

When analyzing your power needs there are several factors to consider. These design considerations will have an impact on your overall UPS needs:

  • Power environment: single and three-phase
  • Installation environment
  • Power load
  • Availability and battery runtime. There are three basic battery runtime configurations:
    1. UPS with 10 to 15 minutes of runtime and no generator. You are covered for 90 to 95 percent of power outages. You can either use UPS shutdown clients to save your data or stay online as long as possible before the system crashes.
    2. UPS with 10 to 15 minutes of runtime and a generator. You have a very reliable setup and most generators will startup within one minute (five minutes maximum). You are covered for most situations.
    3. Redundant UPSs, generator and two power feeds for dual-corded servers. You have a lot of money and/or are really worried about the power failing. It's time to get a consultative person on-site to help you figure it out.
  • Scalability
  • Power distribution
  • Manageability
  • Operation and maintenance
  • Budget

Other UPS design considerations

The following design guidelines should be reviewed and followed prior to ordering the appropriate UPS solution.

  • Check to see if there’s an adequate electrical supply near the UPS.
  • Find out the dimensions of the UPS and include any battery cabinets.
  • Ensure the UPS can be placed in its final position.
  • Verify that the floor is strong enough to support the UPS and battery cabinets.
  • Confirm that the UPS will have adequate ventilation.
  • Always be sure which wall receptacle is required to plug in the UPS.
  • Verify that the UPS fits your receptacle and power requirements, or engage with electrician to hardwire it.
  • Installing small UPS models behind larger UPS models.
  • Using a UPS and a generator together.
  • Verify the UPS solution meets local building codes.
