  • One or more systems are allowed.
• UPS Groups
  • Name must be unique.
  • At least one group must be present in each system.
  • A maximum of three groups are allowed in each system.
  • For N, N+1, and N+2 system types:
    • Each group in the system may have a different number of UPS modules.
    • Each UPS module in the group must have the same nameplate rating (kVA) value.
    • Each UPS module in the group must have the same derated nameplate rating (kW) value
    • Each group is connected to one load only. No other group can be connected to the same load.

    See the UPS Power Configuration Utility for more information.

  • For 2N, 2(N+1) and 2(N+2) system types:
    • All groups must have the same number of UPS modules.
    • All UPS modules in the groups must have the same nameplate rating (kVA) value.
    • All UPS modules in the groups must have the same derated nameplate rating (kW) value.
    • Depending on the number of groups present in the system, a load may be shared by two groups.

    See the UPS Power Configuration Utility for more information.
