PART 1 - GENERAL
1.01
SUMMARY
A.
This specification describes a three-phase continuous duty, on-line, double conversion,
solid-state uninterruptible power system, hereafter referred to as the UPS. The UPS
shall operate in conjunction with the existing building electrical system to provide power
conditioning, back-up and distribution for critical electrical loads. The UPS shall consist
of, as required by the project, the UPS module, battery cabinet(s), and accessory
cabinet(s) for transformers, maintenance bypass, parallel tie, and distribution
applications, and other features as described in this specification.

GUIDE SPECIFICATION
Model Eaton 9390 20-160 kVA
UPS module containing a Rectifier, Inverter, Battery Charger, Static Bypass, and
associated Control and Monitor Panel.
Battery string(s) in Line-and-Match Battery Cabinets.
Line-and-Match accessory cabinets for transformer, maintenance bypass,
parallel tie, and distribution applications.
Non-matching wall mounted or floor standing maintenance bypass cabinets or
multi-module parallel tie cabinets.
Normal: Utilizing commercial AC power, the critical load shall be continuously
supplied by the Inverter. The Inverter shall power the load while regulating both
voltage and frequency. The Rectifier shall derive power from the commercial AC
source and shall supply DC power to the Inverter. Simultaneously, the Battery
Charger shall charge the battery.
Battery: Upon failure of the commercial AC power, the critical load shall continue
to be supplied by the Inverter, which shall obtain power from the batteries without
any operator intervention. There shall be no interruption to the critical load upon
failure or restoration of the commercial AC source.
Recharge: Upon restoration of the AC source, the Charger shall recharge the
batteries and simultaneously the Rectifier shall provide power to the Inverter.
This shall be an automatic function and shall cause no interruption to the critical
load.
Bypass: If the UPS module must be taken out of the Normal mode for overload,
load fault, or internal failures, the static bypass switch shall automatically transfer
the critical load to the commercial AC power. Return from Bypass mode to
Normal mode of operation shall be automatic. No-break transfer to and from
Bypass mode shall be capable of being initiated manually from the front panel.
Energy Saver: The UPS shall continuously monitor the voltage and frequency of
the bypass source. When the source parameters are within acceptable limits, the
