Electromechanical equipment, including generator sets, transfer switches, switchgear, and accessories, can cause bodily harm and pose life-threatening danger when improperly installed, operated, or maintained. To prevent accidents be aware of potential dangers and act safely. Read and follow all safety precautions and instructions. SAVE THESE INSTRUCTIONS. This manual has several types of safety precautions and instructions: Danger, Warning, Caution, and Notice. DANGER Danger indicates the presence of a hazard that will cause severe personal injury, death, or substantial property damage. WARNING Warning indicates the presence of a hazard that can cause severe personal injury, death, or substantial property damage. CAUTION Caution indicates the presence of a hazard that will or can cause minor personal injury or property damage. NOTICE Notice communicates installation, operation, or maintenance information that is safety related but not hazard related. Safety decals affixed to the equipment in prominent places alert the operator or service technician to potential hazards and explain how to act safely. The decals are shown throughout this publication to improve operator recognition. Replace missing or damaged decals. Accidental Starting WARNING Accidental starting. Can cause severe injury or death. Disconnect the battery cables before working on the generator set. Remove the negative (–) lead first when disconnecting the battery. Reconnect the negative (–) lead last when reconnecting the battery. Disabling the generator set. Accidental starting can cause severe injury or death. Before working on the generator set or equipment connected to the set, disable the generator set as follows: (1) Press the generator set off/reset button to shut down the generator set. (2) Disconnect the power to the battery charger, if equipped. (3) Remove the battery cables, negative (–) lead first. Reconnect the negative (–) lead last when reconnecting the battery. Follow these precautions to prevent the starting of the generator set by the remote start/stop switch. TP-7151 9/19 5 Hazardous Voltage/Moving Parts DANGER Hazardous voltage. Will cause severe injury or death. Disconnect all power sources before opening the enclosure. DANGER Hazardous voltage. Moving parts. Will cause severe injury or death. Operate the generator set only when all guards and electrical enclosures are in place. 6 TP-7151 9/19 Introduction This manual provides instructions for using the following communication protocols with the APM603 controller: • Modbus® RTU and TCP • Simple Network Management Protocol (SNMP) • BACnet® Information in this publication

  • FFU-HE High Efficiency Fan Filter Unit
    FFU-HE High Efficiency Fan Filter Unit Price High-Efficiency Fan Filter Units (FFU-HE) are the most energy efficient line of fan filter units (fan filter modules) on the market today. Designed specifically for use in cleanrooms, pharmacies, pharmaceutical manufacturing facilities and laboratories, the FFU-HE delivers high volumes of HEPA (or ULPA) filtered air at low sound levels while reducing energy consumption by 15 to 50% versus comparable products. Typical Applications Fan Filter Units are used in critical FFU-HE, Roomside FFU-HE, Bench Top Removable Filter Replaceable Filter applications such as healthcare, Ducted Inlet Non-Ducted pharmaceutical compounding, or microelectronics manufacturing. With the integrated HEPA or ULPA filters, ultra-clean air is delivered with a unidirectional vertical downward airflow pattern into the space. The integrated high efficiency motors are designed to overcome the static pressure of the filter, and are ideal for retrofit applications where the FFU-HE Filter Options air handler is not able to provide the required static. Product Information FFU-HE is available in 24x24, 24x36 and 24x48 modules, in both aluminum, stainless steel and hybrid construction. Both PSC and EC motors are available, and have been optimized for industry leading energy efficiency. HEPA filters are typical, while ULPA are available as an option. FEATURES AND OPTIONS High Energy Efficiency • High Energy Efficiency • Industry leading energy efficiency means lower operating costs, potentially saving thousands of dollars in electricity per year. • High Airflow Capacity • Energy consumption as low as 55 Watts at 90 fpm (2x4 module) • Complete Control and • See performance data for specific energy consumptions Monitoring via BACnet High Airflow Capacity • Roomside Removable • High airflow capacity per unit means fewer units and lower first cost (RSR) filter • Active filter area is maximized with the Bench Top Replaceable (BTR) filter, with 2x4 units able to achieve up to 930 CFM.

  • Bacnet™ and Lonworks®: Compared and Contrasted
    BACnet and LONWORKS : Compared and Contrasted ® PolarSoft Inc. David Fisher, PolarSoft Inc. 914 South Aiken Avenue May 2004 Pittsburgh PA 15232-2212 412.683.2018 voice 412.683.5228 fax Introduction [email protected] Over the course of the past 20 years, building owners, managers and www.polarsoft.biz consulting/specifying engineers have become increasingly frustrated by incompatibilities and limited opportunities for the integration of building automation and control systems. Although the sophistication and flexibility of networking and communications technologies in general have been increasing geometrically, controls systems for buildings have carried forward a legacy of proprietary thinking which has impeded the natural migration of many of the benefits of open networking technology into building systems. The bottom line effect has been that, while many modern building automation and control systems incorporate some of the latest advances in networking technology, the benefits of interoperability, configuration flexibility, and performance-based pricing have yet to be realized by building owners and operators. Through accident or intent, building automation and controls systems have simply failed to embrace true open systems concepts effectively for building owners. Several solutions have come into widespread use and are changing this situation permanently and dramatically. One such solution is called BACnet: The Building Automation and Controls Network. BACnet is an international standard for computers used in building automation and controls systems that was developed between 1987 and 1995 by ASHRAE. In December of 1995, BACnet was also adopted by ANSI, and is now an American National Standard (ANSI/ASHRAE 135-1995, ANSI/ASHRAE 135-2001, ANSI/ASHRAE 135-2004).
