12.1 Notes
1. Nominal rectifierAC input current (considered continuous) is based on full rated output load.
Maximum currentincludes nominal input currentand maximum battery recharge current
(considered noncontinuous). Conti nuous and noncontinuous current limit are defined in NE C
100. Maximum input current is controlled by current limit setting which is adjustable. Values
shown are for maximum setting of 125%. Standard factory setting is 115%.
2. Nominal AC output cur rent (considered continuous) is based on full rate d output load.
Maximum current includes nomin al output current and overload for 10 minutes.
3. Bypass AC input current (considered continuous)is ba sedon 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 overcurrentprotection devices.
5. UPS output load cables must be run in separate conduit from input cables.
6. Power cable from module DC bus to batte ry should be sized for a total maximum 2.0 volt line
drop (measured at themodule) at maximum discharge current.
7. Grounding conductors to be sized per NEC 250-122. Neutral conductors to be sized for full
capacity for systems with 4-wire loads and half c apacity for systems with 3-wire loads. NOTE:
A neutral conductor is requir ed from each Multi-Module Unit output t o the System Control
Cabinet.
8. Rectifier AC Input: 3-phase, 3-wire , plus ground
ACOutput,SCCtoLoad:3-phase,3or4-wire,plusground
Bypass AC Input: 3-phase, 3 or 4-wire, plus ground
Module DC Input from Battery: 2-wire, (positive and negative)
9. All wiring is to be in accordance with National and Local Ele ctrical Codes.
10. Minimum clear ance is 2 feet above UPS.
11. Top or bottom cable entr y through removable access plates. Cut plate to suit conduit size.
12. Control w iring and power cables must be run in separate conduits. Co ntrol wiring must be
stranded tinned conductors.
13. 7% maximum input har monic current and 0.92 lagging input power factor at full load with 6-
pulse rectifier and optional input filter (4% w ith 12-pulse rectifier and input filter).
30% maximum input harmonic cur rent and 0.85 lagging input power factor at full load
without optional input filter (9% with 12-pulse rectifier ).
14. Dimensions and weights do not include the System Con trolCabin etr equired for Multi-
Module Systems.
