Notes on Tables
1. Nominal input current (considered continuous) is based on full-rated output load. Maximum
current includes nominal input current and maximum battery recharge current (considered
noncontinuous). Continuous and noncontinuous current are defined in NEC 100.
2. Maximum input current is controlled by the current limit setting, which is adjustable. Values
shown are for a maximum setting of 125%. The standard factory setting is 125%. If a smaller
input feed breaker is used, the input current limit must be adjusted accordingly.
3. For units with an input transformer, the Rectifier Input Feed Breaker must be set to handle the
Liebert NXL transformer inrush of up to eight times the nominal current.
4. For breaker coordination while the module is overloaded, see the current-versus-time values on
the overload curves, Figures 23 and 24.
5. Nominal battery voltage is shown at 2.0V/cell.
