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 maximum current limit. If a smaller input feed breaker is used, the input current
limit can be adjusted; see your Emerson representative for more information.
3. The Rectifier Input Feed Breaker must be set to withstand the Liebert NXL transformer inrush of
up to eight times the nominal current.
4. All recommended external overcurrent protections are based on 100% rated breakers.
5. For breaker coordination while the module is overloaded, see the current versus time values on
the overload curves.
6. Nominal battery voltage is shown at 2.0 volts/cell.
