2 Technical Data Page 2 Effective: March 1 Introduction Combination and Automatic are designed for applications where preventive maintenance, inspection and testing must be accomplished while maintaining continuity of power to the load. This is typically required in critical life support systems and standby power situations that require safe maintenance of the system with no disruption of the power. Combination and Automatic meet or exceed all industry standards for endurance, reliability and performance. They are listed under Underwriters aboratories U 1008 tandard for Transfer witch Equipment. They also comply with emergency and standby system requirements as defined in NFPA 99 for health care facilities.

All switches include the basic features necessary for normal operation as standard (see next page). also offers an extensive array of optional features and accessories that permits the user to customize a new transfer switch to match the application. The customization process is simple. elect the appropriate catalog number for your application from the charts. Then choose any optional features or accessories needed to complete the project requirements.

3 Technical Data Effective: March 1 Page 3 Features, Benefits and Accessories uperior Main Contact tructure The Combination and Automatic Transfer witch meets or exceeds the standards set forth in U 1008 and U 489. No other transfer switch manufacturer has meet the rigid testing requirements of this combination of standards. Completely enclosed contacts provide both safety and reliability. They also ensure the integrity of the contact assemblies and minimize the need for periodic maintenance of the contacts, reducing downtime and maintenance time. ong-ife Design Main contacts employ developed DE-IN arc quenchers and contact arcing horns for extended in-service life and reduced pitting and burning of contact services. imple, Reliable peration The automatic transfer switch is operated by a single, unidirectional gear motor transfer mechanism that receives its power from the source to which it is being transferred. Bypass and Isolating Mechanisms are manually operated by handles which ensure true quick-break, quick-make operation under full load conditions. ecure Isolation Triple interlocking of AT main contacts (2 mechanical, 1 electrical) ensure that both power sources cannot be simultaneously connected to the load. Bypass switches are key interlocked to prevent paralleling of sources. Versatile Control Control ogic Panel interconnects with Power witching Panel via insulated keyed plug connectors to permit total isolation of controls for routine maintenance. Engine tarting Contact Provides a 10 ampere, 30 Vdc contact closure to initiate engine starting upon failure of the Normal Power ource. This feature, specifically designed for low current applications, is wired to red terminal blocks on the control panel for ease of identification and maintenance. Full Phase Protection Provides phase failure protection on each phase of the Normal Power ource. hould the voltage drop below a pre-selected, fully adjustable value on any phase, a signal is sent to initiate engine start. Time Delay Normal to Emergency Provides a delay, adjustable 0-30 minutes, when transferring from the Normal Power ource to the Emergency Power ource. This accessory does not affect the engine starting circuit. Timing begins when emergency/ standby voltage begins. Time Delay engine tart This accessory is for use when the Emergency Power ource is an engine generator. It delays initiation of the engine start circuit for seconds (adjustable) in order to override momentary power outages or voltage fluctuations of the Normal Power ource. Time Delay Emergency to Normal Delays the retransfer from the Emergency/tandby Power ource to the Normal Power ource to permit stabilization of the Normal Power source before retransfer is made. Timing is adjustable 0-30 minutes and begins when the Normal Power ource appears. If the Emergency/ tandby Power ource fails during timing, retransfer to the Normal Power ource is immediate, overviding the time delay. Time Delay Engine Cooldown Permits the engine to continue to run unloaded after retransfer to the Normal Power ource has been made. Timing is adjustable 0-30 minutes and begins when retransfer is completed. Fully Rated Neutral Provides a fully rated solid neutral for all 2- and 3-pole switches. All 4-pole switches are supplied with switched neutral contacts of identical construction and rating as the power poles and are mounted on the power contact shaft, integral to the completely enclosed contact assemblies. Multi-Tap Voltage election Provides line voltage selection of 208, 220, 240, 380, 415, 480 or Vac, 50 to 60 Hz by proper insertion of voltage selection plug. Emergency/tandby ource Monitoring Relay monitor prevents transfer from the Normal Power ource to the Emergency/tandby Power ource until that source has attained 90% of nominal voltage and frequency. In addition, when the switch is in the Emergency/tandby position and that source falls outside the monitored parameters, a load retransfer is initiated to the Normal Power ource if it is present. Indicating ights Indicate switch position. Green for Normal position, red for Emergency/ tandby position. Relay Auxiliary Contacts Provides three Form C contacts for each source. n the Normal Power ource, energized when normal voltage is present. n the Emergency/tandby Power ource, energized whenever emergency/standby voltage is present.

4 Technical Data Page 4 Effective: March 1 Description, Continued Benefits The Combination and Automatic Transfer witch eliminates all of the complicated drawout mechanisms required on competitive products for total isolation of the transfer switch, and instead utilizes foolproof mechanical Kirk Key interlocking combined with a positive Total Isolation Mechanism. The result is the safest, easiest-to-operate bypass isolation switch available in the marketplace today. When the transfer switch is in the Isolated position, complete testing of the AT can be accomplished via a special insulated keyed connector. This allows the operator to completely test the entire operating sequence of the AT while maintaining power to the connected load. The Combination and Automatic Transfer witch utilizes modified molded case switches, designed specifically for high duty repetitive load transfer, as a means to bypass and totally isolate the transfer switch. This device provides for a reliable, rugged installation that can withstand very high level short circuits. In addition, ampere units utilize eries C Technology that offers the highest Withstand, Closing and Interrupting Rating available in the marketplace today.
