Operator Interface (OI), the level logic controller (LLC), and LLC 1/0 modules in the <br /> control panels. <br /> 1. The UPS shall be on line system which provides continuous, no break power <br /> during complete blackouts or momentary interruptions. The UPS shall not <br /> utilize a ferroresonant transformer. The UPS shall provide +/- 3% load <br /> regulation while producing computer grade powerwith less than 5%THD.The -- <br /> UPS shall be rated to provide a minimum of VA output shown on Contract <br /> drawings at 120 VAC at an efficiency of 95%. <br /> 2. Mount UPS in control compartment and provide all necessary power wiring. <br /> Plug cords and receptacles shall be provided so that the UPS can be readily <br /> bypassed with power being obtained directly from the panelboard. <br /> 3. Submit load calculations of all connected 120 VAC loads showing UPS is <br /> adequately sized. <br /> 4. The UPS shall be an American Power Conversion (APC) Smart-Slot, or - <br /> approved equal. <br /> D. Miscellaneous Devices -- <br /> 1. RFI filters to be for power line radio frequency protection, CORCOM VK series <br /> or approved equal. _ <br /> 2. Analog 4-20 mA signals on wiring to all field instruments shall have surge <br /> protection terminals installed at panel originating loop power. Surge protection <br /> terminal blocks shall be fused and limit maximum working voltage to 32 VDC <br /> and rated for 50 mA. Loop surge protection terminal blocks to be MTL, or <br /> approved equal. <br /> 3. Data wiring (wiring in "D" Series conduits) between communication devices <br /> shall be protected on both ends by fused terminal surge protectors rated for <br /> use with data signal. Data terminal surge protectors shall be MTL or approved <br /> equal. — <br /> 4. DC Power Supplies <br /> a. DC power supplies to be linear type non-switching VDC, quantity and <br /> sizes per drawings, Power One International Series Linear, Sola, or <br /> approved equal. <br /> 5. Each isolator shall provide complete isolation of the 4-20 mA output signal _ <br /> from the input signal and isolator power supply. Each isolator shall have all <br /> solid state circuitry mounted in a plug-in module. The 4-20 mA output signal <br /> shall be capable of driving a 600 ohm load. Accuracy shall be +/- 0.25% of <br /> span. The isolator shall be powered as shown on Contract Drawings. Each <br /> isolator shall have a seven year warranty. The isolators shall be as <br /> manufactured by AGM Electronics, Action Instruments, or approved equal. <br /> at 10 <br /> 6.
