Liebert Series 600T UPS, 65-225 kVA, Single Module A-1
Appendix A: Site Planning Data
65-225 kVA Single Module Systems
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 250-122. Neutral conductors to be sized for full capacity -- per
NEC 310-15 (b)(4) -- for systems with 4-wire loads and half capacity for systems with 3-wire loads.
8. Rectifier AC Input:3-phase, 3-wire, plus ground
AC Output to Load: 3-phase, 3 or 4-wire, plus ground
Bypass AC Input:3-phase, 3 or 4-wire, plus ground
Module DC Input from Battery:2-wire, (positive and negative) plus ground
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 100-225
kVA modules are 8” narrower (48” vs. 56”) and are top-entry only. Tables show SpaceSaver modules, where available.
Cut access plates to suit conduit size.
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.
