Engineering Power, Quick, Special Desing, Experience, Wide Service GC Series Scope This document describes a continuous duty three phases Alternating Current (AC) input or DC input , stand-alone, single phase AC output Uninterruptible Power System (UPS). The GC series range meets customers’ technical specifications for industrial applications such as: Power generation Oil and gas offshore developments (platforms, FPSO, etc…) Oil and gas transportation (pipelines…) Oil and Gas treatment plants (refineries, petrochemical units…) Railways and undergrounds control and signalling systems, etc......

Energy & Power Conversion General requirements ISO certification EPC Energy is certified by the Natinal quality assurance (NQA), as a company with a total quality and environmental control system in accordance with the ISO 9001 and ISO 14001. Applied standards The GC Series range of UPS shall have the CE mark in accordance with the Safety and EMC Directives 73/23, 93/68 and 89/336, 92/31, 93/68. GC Seies is designed and manufactured in accordance with the following international standards: IEC950 Safety of information technology equipment including electrical business equipment IEC439 Low...

Engineering Power, Quick, Special Desing, Experience, Wide Service GC Series Input supply failure Upon fault of the input AC source, the rectifier-charger stops while the load remains supplied by the UPS inverter. Upon Mains input fault detection, the inverter immediately draws its power from the associated battery without switching. While the inverter is powered by the battery, indication is provided of the actual autonomy percentage remaining. When reaching the end of battery autonomy, an alarm occurs and the static switch immediately switches the load onto reserve supply, without...

Energy & Power Conversion FRONT PANEL / STRUCTURE OF FRONT PANEL The front panel of the UPS contains a 2x16 character LCD (Liquid Crystal Display), control buttons and leds. Via LCD, measurements and status / alarm messages are displayed in a format, which can be easyly understood. Parts in front panel and their functions are given below. LCD DISPLAY, MEASUREMENTS MENU 1) LCD Display: Measured values, status and alarm messages of the equipment are displayed in this 2x16 character LCD display 2) Up / Silence Button: In menus, this button is used to see the previous item (up). In adjustments,...

Engineering Power, Quick, Special Desing, Experience, Wide Service Static Power Inverters The content of the second line of Measurements Menu (status and alarm messages) is given below. Indicates that the load is connected to bypass supply. In this case, load is unprotected against interruptions. Indicates that the load is fed by the voltages produced by the UPS. If batteries are connected and battery circuit breaker is in ON position, load is protected against interruptions. Indicates that there is more that 100% load at the UPS output. If the UPS is feeding load from inverter, after a...

Energy & Power Conversion Mechanical data Enclosure The GC series UPS is housed in a space-saving modular enclosure including front doors and removable panels (standard external protection IP 20). The enclosure is made of sheet steel. The doors can be locked. The enclosure is of the floor mounted type. For harsh environmental conditions (dust, water), a higher degree of protection, of up to IP42 is available in option. Specific system design can be achieved up to IP54. In such extreme cases, technical characteristics mentioned in this document are not maintained. Ventilation Fan-assisted...

Energy & Power Conversion Centralised parallel configuration System description The centralised paralleling philosophy enables UPSs without reserve static switches to be connected in parallel. Hereby the reserve supply to the loads works with one central reserve cubicle. Again, UPSs of the same rating are connected in parallel. Each is GC series supplied with the parallel kit option, which includes one printed circuit board POB (Parallel Operation Board) individually. Each UPS includes only one inverter static switch, which is paralleled with the single reserve static switch. Operating...

Engineering Power, Quick, Special Desing, Experience, Wide Service Remote monitoring options Customer interface relay It is possible to increase the number of inputs/outputs. These input/outputs can be used to monitor several parameters specified by the user. Each board includes: 3 inputs (from voltage free contacts – Not provided) Four outputs to drive voltage free contacts (provided). The requested umber of output information will be made available on double-pole change-over (dpco) contacts (8A/250V AC1; 8A/30V DC1; 1A/60V DC1). Number of input failures Data storage function Top cable...
