Liebert® EXL™ S1 UPS
For a 1000-1200kVA Single-Module or Multi-Module (Distributed Static Switch)
Uninterruptible Power System
These specifications describe requirements for a continuously rated, solid state Uninterruptible Power System (UPS) optimized for maximum efficiency and power density. The UPS utilizes a double-conversion, transformer free topology, whereby the output power supplied is derived directly from the UPS without the need for an internal step-up output transformer. The UPS will be used to operate in conjunction with the existing building supplies and shall provide high quality power distribution for critical loads. All performance values specified shall be for the equipment needed to operate at the same voltage as the electrical system. The UPS, with the exception of the battery system and maintenance bypass, shall be factory assembled and tested at the specified system voltage and reconnected on site without addition of field supplied power conductors.
The manufacturer shall design and furnish all materials and equipment to be fully compatible with electrical, environmental and space conditions at the site. The UPS shall include all equipment to integrate the AC power source to the intended load and be designed for unattended operation.
The UPS and all associated equipment and components shall be manufactured in accordance with the following applicable standards:
The UPS shall be UL listed per UL Standard 1778, latest edition, Uninterruptible Power Supplies, and shall be CSA certified.
The UPS shall be provided with a Short Circuit Withstand Rating label denoting the maximum source fault short circuit current that is applicable to the unit. The withstand rating shall be independently verified by a nationally recognized third-party lab. Self certification shall not be acceptable.
The UPS shall withstand input surges to both the rectifier and bypass, when configured as a dual-input unit, without damage per the criteria listed in ANSI C62.41, Category B3 (6kV). The manufacturer shall provide evidence of compliance and test data upon request.
(Optional) The UPS shall comply with FCC Rules and Regulations, Part 15 Subpart B §15.107 Conducted Limits Class A. This compliance is legally required to prevent interference with adjacent equipment. The UPS shall have a label stating FCC compliance. The manufacturer shall provide evidence of compliance upon request.
The UPS shall be compatible with the wiring practices, materials and coding in accordance with the requirements of the National Electrical Code, OSHA and applicable local codes and standards. Overcurrent devices provided in the UPS shall include trip functions as indicated on the project drawings. Provisions shall be made in the cabinets to permit installation of input, output and external control cabling, using raceway or conduit for top and bottom access to input, output, bypass and DC connections. Connection cabinets shall provide for wiring gutter and wire bend radius as defined by the NEC and UL.
The UPS and matching Battery Cabinets shall be certified to the International Building Code (IBC) 2015 with seismic performance of Sds=2.00, Ip=1.5 and z/h=1.0. Optional seismic brackets shall be available from the UPS manufacturer for use in compliance with this certification.
The Quality System for the engineering and manufacturing facility shall be certified to conform to Quality System Standard ISO 9001 for the design and manufacture of power protection systems for computers and other sensitive electronics.
