    1. FABRICATION

      1. Materials


    All materials of the UPS shall be new, of current manufacture, high grade and shall not have been in prior service except as required during factory testing. All active electronic devices shall be solid-state. All power semiconductors shall be sealed. Control logic and fuses shall be physically isolated from power train components to ensure operator safety and protection from heat. All electronic components shall be accessible from the front without removing sub-assemblies for service access.
        1. UPS Internal Wiring


    Wiring practices, materials and coding shall be in accordance with the requirements of the National Electrical Code, OSHA and applicable local codes and standards. All bolted connections of busbars, lugs and cables shall be in accordance with requirements of the National Electric Code and other applicable standards. All electrical power connections shall be torqued to the required value and marked with a visual indicator.
        1. Field Wiring


    All field wiring power connections shall be to tin-plated copper busbars for connection integrity. Busbars shall have adequate space to allow two-hole long-barrel compression type lugs forming a permanent connection between field wiring and field-installed lugs.

    Provisions shall be made in the cabinets to permit installation of input, output and external control cabling using raceway or conduit. Provision shall be made for top and bottom access to input, output, bypass and DC connections. In conformance with the NEC, connection cabinets shall provide for adequate wire bend radius.
        1. Construction and Mounting


    The UPS shall be in NEMA Type 1 enclosures, designed for floor mounting. The UPS shall be structurally adequate and have provisions for hoisting, jacking and forklift handling. Maximum cabinet height shall be 78.in. (1990mm).

    The UPS shall be NEMA Type 1-compliant, with front doors open to enable safe change of air filters without the need for shutdown.
        1. Cooling


    Adequate ventilation shall be provided to ensure that all components are operated well within temperature ratings.

    Temperature sensors shall be provided to monitor the UPS’s internal temperature. Upon detection of temperatures in excess of the manufacturer’s recommendations, the sensors shall cause audible alarms to be sounded and visual alarms to be displayed on the UPS control panel. An internal, factory-mounted sensor for room ambient temperature shall be provided to give an alarm if the temperature of the inlet air to the UPS is above specified limits. Air filters shall be located at the point of air inlet and shall be changeable. No service clearance or ventilation shall be required in the rear of the system.
      1. EQUIPMENT

        1. UPS System


    The UPS system shall consist of an IGBT power factor-corrected rectifier, DC-DC converter and three-phase, transformer-free inverter, bypass static transfer switch, bypass synchronizing circuitry, protective devices and accessories as specified. The specified system shall also include a battery disconnect breaker and battery system.

    1. Surge Protection

    The UPS shall have built-in protection against: surges, sags and overcurrent from the AC source. The protection shall meet the requirements of ANSI C62.41 B3 including:

    • 6kV, 100kHZ ring wave, line-to-line, line-to-neutral, line-to-ground and neutral-to-ground

    • 6kV, combined wave, line-to-line, line-to-neutral, line-to-ground and neutral-to-ground

    1. Output Protection

    The UPS shall be protected against sudden changes in output load and short circuits at the output terminals. The UPS shall have built-in protection against permanent damage to itself and the connected load for all predictable types of malfunctions. Fast-acting, current-limiting devices shall be used to protect against cascading failure of solid-state devices. Internal UPS malfunctions shall cause the module to trip off-line with minimum damage to the module and provide maximum information to maintenance personnel regarding the reason for tripping off-line. The load shall be automatically transferred to the bypass line uninterrupted for an internal UPS malfunction. The status of protective devices shall be indicated on a graphic display screen on the front of the unit.
