United Automation Infresco-S 4kW Manuals

Introduction The Infresco-S 4kW is part of a family of controllers designed to provide energy saving when used with Quartz Infrared Halogen Lamps or other Heating and Lighting Products. The ‘S’ model switches Soft Starts the load each time power is applied The microcontroller-based unit incorporates zero-voltage switching and a soft-start function to eliminate the lamps’ initial high inrush current – potentially increasing lamp life by as much as 30%. Installation of the unit is simple and once installed is relatively maintenance-free. Product Features
Extends Lamp Life.
Soft-start/zero-voltage switch-off.
Low-cost.
Easy to install. Applications: patio areas, smoking shelters, restaurants, warehouses, workshops and garden lighting. Installation Important: Read carefully the following information before installing the unit. The Infresco-S 4kW should be fixed securely using the four mounting holes accessible from the front of the unit. Remove the lid to access the mounting holes. To ease installation, a mounting template is provided on the next page to locate the 4 mounting hole centres. IMPORTANT! The unit must be orientated with the cable glands facing down. Wiring It is recommended that installation and maintenance of this equipment should be done with reference to the current edition of the I.E.E. wiring regulations (BS7671) by suitably qualified/trained personnel. These regulations contain important requirements regarding safety of electrical equipment (for International Standards refer to I.E.C/ directive IEC950). Warning! Ensure all earth wires are connected to maintain earth continuity to the lamp fittings. Isolate the mains supply before wiring this unit. The unit is fitted with two cable glands. Only one cable should be fitted per gland to maintain the unit’s IP rating. When fitting two lamps, refer to Wiring Diagram for an alternative wiring configuration using a junction box. The mains supply connects to the terminal block marked ‘LINE’. Connect the supply LIVE to the ‘L’ terminal, NEUTRAL to the ‘N’ terminal and EARTH to the ‘E’ terminal. The lamps connect to the terminal block marked ‘LOAD’. Connect the load LIVE to the ‘L’ terminal, NEUTRAL to the ‘N’ terminal and EARTH to the ‘E’ terminal. If two lamps are to be fitted they must be wired in parallel. Check all wiring - particularly the line and load connections and make sure the cable glands are tightened. Mounting Template Commissioning Set the on-time preset (VR1) to a time period of between 1 and 40 minutes. VR1 is located at the top of the printed circuit board as shown above. Replace the lid and switch on the mains supply to the unit. Press the push-button on the front of the unit to switch the lamps on. Technical Specification Supply Voltage 230VAC +/- 10% 50 Hz Switching Capacity 4kW Max. Current Consumption (control circuit) 50mA Terminals 2.5mm2 Rising Clamp Operating Temperature -20 to 40°C Protection Rating IP65 Gland Diameter Max Cable Entry 2.5mm² Enclosure Dimensions (WxLxH) 100x100x60 (mm) Mounting Template Use this template to locate the 4 mounting hole centres prior to drilling. IMPORTANT! The drilling of any additional holes will immediately void the warranty of this unit. The unit must be orientated with the cable glands facing down.
