Notes
1.Nominal rectifier AC 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 limits are defined in NEC 100. Maximum input current is controlled by current limit setting which is adjustable. Values shown for maximum setting are 125% of nominal input current. Standard factory setting is 115%.
2.Nominal AC output current (considered continuous) is based on full rated output load. Maximum current includes nominal output current and overload current for 10 minutes.
3.Bypass AC input current (considered continuous) is based on full rated output load.
4.Feeder protection (by others in external equipment) for rectifier AC input and bypass AC input is recommended to be provided by separate overcurrent protection devices.
5.UPS output load cables must be run in separate conduit from input cables.
6.Power cable from module DC bus to battery should be sized for a total maximum 2.0 volt line drop (measured at the module) at maximum discharge current.
7.Grounding conductors to be sized per NEC
8.Rectifier AC

9.All wiring is to be in accordance with National and Local Electrical Codes.
10.Minimum overhead clearance is 2 feet above UPS.
11.Top and bottom cable entry standard through removable access plates. However, SpaceSaver versions of the
12.Control wiring and power cables must be run in separate conduits. Control wiring must be stranded tinned conductors.
13.7% maximum reflected input harmonic current and 0.92 lagging input power factor at full load with optional input filter.
