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.
Contact your Vertiv representative for more information.
3. The Rectifier Input Feed Breaker must be set to handle the
®
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 in
Figures 43 and 44 .
5. Nominal battery voltage is shown at 2V/cell.
