LIEBERT® APM™ 3-PHASE UPS: 15-90KVA/KW, 60HZ, 208-600VAC, SINGLE & DUAL INPUT - SITE PLANNING DATA
BATTERY
NOTES
1. Install in accordance with national and local electrical codes.
2. Input and bypass must share the same single source.
3. A neutral is required from the system AC input source.
A full capacity neutral conductor is recommended.
Grounding conductors are recommended.
4. UPS system input and output cables must be run
in separate conduits.
5. Control wiring must be run in separate conduits.
6. Optional 54 pole, 225A for 45kVA frame only or
optional 54 pole, 400A for 90kVA frame only.
7. Transformer available 480V or 600V input.

The UPS must be fed from a solidly
grounded wye or delta AC source. Not for
use with impedance-grounded systems,
corner-grounded or high leg delta systems. For these applications, an isolation
transformer must be installed between
the AC feed and the UPS.

Notes for Tables
1.Nominal (Nom) current is based on full rated output load at nominal input voltage.
2.Maximum (Max) current (125% of nominal) is short duration for battery recharge
conditions.
3.UPS input and bypass cables must be run in separate conduit from output cables.
4.Nominal battery voltage is shown at 2.0 volts/cell per NEC 480-2.
5.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 non-continuous). Continuous
and non-continuous currents are defined in NEC 215.
Nominal AC output current (considered continuous) is based on full rated
output load. Output breakers are either supplied by the customer or by using
the optional Liebert Bypass Distribution Cabinet.
6.Minimum-sized grounding conductors to be per NEC 250-122. Parity-sized
ground conductors are recommended. Neutral conductors to be sized for full
capacity per NEC 310-15 (b)(4). References are per NEC 2008.
7.Wiring requirements:AC Input:3-phase, 4-wire, plus ground
AC Output: 3-phase, 3- or 4-wire, plus ground
8.All wiring is to be in accordance with national and local electric codes.
9.Minimum access clearance is 36" (914mm) front; ventilation clearance is 24" (610mm)
above and 12" (305mm) in the rear.
10. Top or bottom cable entry through removable access plates. Punch plate to suit conduit
size, then replace.
11. Control wiring and power wiring must be run in separate conduit.
12. Dimensions shown include an internal battery (45kVA frame only).
13. Weights shown do not include an internal battery nor optional cabinets or features.
14. When a Liebert Bypass Distribution Cabinet is not used, the customer must supply the
input circuit breaker with a 120VAC shunt trip. The shunt trip drive capability is 8A.
Additional Notes
• If site configuration includes a backup emergency generator, it is recommended that the
engine generator set be properly sized and equipped for a UPS application. Generator
options would typically include an isochronous governor (generator frequency regulation)
and a UPS-compatible regulator (generator voltage regulation). Consult generator
manufacturer for required generator options and sizing.
• If site configuration includes an automatic transfer switch, refer to Liebert Power Line titled
“Criteria for Application of Automatic Transfer Switches (ATS) With Uninterruptible Power
Supply (UPS) Systems,” publication 91K-PLT-48-02. It is also recommended that the
transfer switch be equipped with auxiliary contacts to provide a UPS “on generator” signal.
Consult transfer switch manufacturer for required transfer switch options and sizing.
• If site configuration requires an external isolated maintenance bypass circuit, it should be
noted that utility AC input might not be in phase with the UPS AC output. Consult an
Emerson sales representative or applications engineer.
