Uninterruptible Power System

PART 1 - GENERAL

1.1 SUMMARY A. This specification describes the operation and functionality of a continuous duty, single-

phase, solid-state, static Uninterruptible Power System (UPS) hereafter referred to as the UPS.

B. The UPS shall utilize modular power protection technology designed to allow internal

redundancy, scalability of power and runtime, and fast mean time to repair (MTTR). The UPS should be configured from five basic components- UPS frames, extended run battery frames (XR frames), power modules, battery modules, and intelligence modules. UPS and XR frames should be capable of shipping with modules installed. XR frames should be capable of communicating battery and runtime status to intelligence modules. Power, battery, and intelligence modules should be hot-swappable and user-replaceable for fast MTTR.

C. Configuration Specifics:

1. The UPS frame(s) should be capable of the following configurations:

____4-8kVA N+1 Redundant Tower ____4-16kVA N+1 Redundant Tower ____4-16kVA N+1 Redundant Tower with nine (9) extra Battery Module slots ____4-8kVA N+1 Redundant 13U Rack-mount ____4-16kVA N+1 Redundant 19U Rack-mount

2. The system power train shall be comprised of hot-swappable, user-replaceable

3.2kW/4kVA and 10% Battery charger circuit power modules, which shall operate in parallel, and be configurable for N+1 redundant operation at rated load.

3. The system shall also include a field-replaceable internal automatic and manual

bypass system module, field-replaceable output power distribution panels, removable input/output wiring tray, standard redundant intelligent modules, battery disconnects, an LCD interface display, EPO, and an integrated UPS network management card with temperature monitoring.

D. In addition, this specification describes the performance, functionality, and design of

the UPS Service Bypass Panel, hereafter referred to as the SBP, the external Battery Systems, and connectivity solutions.

CSI SECTION 16611 STATIC UNINTERRUPTIBLE SYSTEM

E. The UPS and associated equipment shall operate in conjunction with a primary power

supply and an output distribution system to provide quality uninterrupted power for mission critical, electronic equipment load.

F. All programming and miscellaneous components for a fully operational system as

described in this specification shall be available as part of the UPS.

1.2 STANDARDS A. UL 1778 Uninterruptible Power Supply Equipment B. CSA C. FCC Class A D. ISO 9001 E. ISO 14001

1.3 MODES OF OPERATION A. Normal: The input converter and output inverter shall operate in an on-line manner to

continuously regulate power to the critical load. The input and output converters shall be capable of full battery recharge while simultaneously providing regulated power to the load for all line and load conditions within the range of the UPS specifications.

B. Battery : Upon failure of the AC input source, the critical load shall continue being

supplied by the output inverter, which shall derive its power from the battery system. There shall be no interruption in power to the critical load during both transfers to battery operation and retransfers from battery to normal operation.

C. Recharge: Up on restoration of the AC input source, the input converter and output

inverter shall simultaneously recharge the battery and provide regulated power to the critical load.

D. Automatic Bypass: The automatic bypass shall be used to provide transfer of critical

load from the Inverter output to the bypass source. This transfer, along with its retransfer, shall take place with no power interruption to the critical load. In the event of an emergency, this transfer shall be an automatic function.

E. Manuel Bypass: The system shall be equipped with an internal make-before-break two

pole switch to electrically isolate the UPS from the input and output during preventative maintenance, module upgrades, or limited frame service. The manual bypass shall also be considered a partial ‘wrap-around’ bypass, and shall be configured to wrap around the power modules (recitifier, battery charger, inverter) , and battery modules in the same manner as the automatic bypass will still supplying surge and EMI filtering, and overcurrent protection. There will be a positional sense supplied to alert users that the UPS is in manual bypass.

CSI SECTION 16611 STATIC UNINTERRUPTIBLE SYSTEM

F. External Service Bypass Panel (SBP): The maintenance service bypass cabinet shall

provide power to the critical load bus from the bypass source, during times where maintenance or service of the UPS frame is required or when removal of the frame is desired. The SBP shall provide a mechanical means of complete isolation of the UPS from the electrical wiring of the installation. The SBP shall be constructed in a freestanding, rack mounted or wall-mounted NEMA 1 enclosure unless otherwise stated in this specification. It shall be designed for either three phase input or single phase input with a “ no break” transfer between bypass and UPS power.
