SECTION 1 - INTRODUCTION 1.1 General Description The OVATION™ Series Automatic Transfer Switch (ATS) system, used in conjunction with a standby generator, provides a convenient, economical way to maintain power in a home or business during a utility outage. The transfer switch senses when utility power is lost, starts a permanently installed generator and transfers the connected loads to generator power, reversing the sequence when utility power is restored.
1.2 Standard Configurations: TABLE 1.
RETROFIT: NEW CONSTRUCTION OR RETROFIT 1.4 How the OVATION™ Series Automatic Transfer Switch Works: 1) When the utility power fails or drops below 190 volts or 54 Hz or exceeds 280 volts or 66 Hz, the OVATION™ Automatic Transfer Switch will begin the generator starting sequence after a 5-second delay. 2) Once the generator is started, the system is programmed to allow the generator to warm up and wait for possible successful utility power grid re-strike (approx.
3) The transfer switch will automatically monitor if the generator has sufficient available capacity to operate any or all appliances connected to PowerPause™ Load Management modules, starting with priority 1 Load, based upon appliance power requirements “learned” from a setup utility at the time of the transfer switch installation. One or more PowerPause™ Load Management connected appliances may operate simultaneously as long as the generator capacity utilization does not exceed 85%.

1.5.5 Remote PowerPause™ Relay Box (Optional) The PowerPause ™ Relay Box can control up to two 2-Pole (240VAC) 30A or 50A loads by interrupting power to the load when commanded by the PowerPause ™ Load Management Module, thereby preventing overloading the standby generator. Packaged in a NEMA 3R enclosure, the PowerPause ™ Relay Box can be conveniently installed indoors or outdoors adjacent to the load center, OVATION™ Automatic Transfer Switch or controlled load. See Photo at right. 1.5.
SECTION 2 – COMPATIBLE EQUIPMENT 2.1 Compatible Generators In order for the OVATION™ Series ATS to function as designed, it must be connected to a permanently installed, automatic starting generator, with a continuous supply of fuel, such as gasoline, diesel, LPG or natural gas. Additionally, gasoline or diesel-powered generators must be equipped with automatic choke and electric/remote start. All OVATION™ Series ATS systems supports 2-wire (ON, +12V) or 4-wire (CRANK, ON, +12V, -12V) generator signaling.
SECTION 3 – PREPARING FOR INSTALLATION ALL Gen/Tran OVATION™ Series ATS systems should be installed by a professional licensed electrician familiar with electrical wiring and codes, and experienced in working with generators. Gen/Tran accepts no responsibility for accidents caused by incorrect and/or improper installation. OVATION™ Series ATS systems are designed and intended for installation with 120/240VAC, single-phase applications ONLY. 3.
2) 3) 4) Your Installer will determine if all of the desired back-up loads can be operated by the generator at the same time. If not, you will need to purchase/install PowerPause™ Load Management modules to manage pre-determined loads so as to not exceed the generator capacity. If PowerPause™ Load Management modules are required, determine which appliances will be connected to the PowerPause™ modules (up to six appliances, 240VAC, 50A).
Examples of critical loads that are NOT recommended (NOT OK) to be connected to the PowerPause ™ Load Management Module and Relay Box are: • • • • • • • • • • • Refrigerators and freezers Aquariums Central heating systems (gas, oil, electric) Furnace fan (air handler) Sump pumps Septic lift pumps Pool and spa anti-freeze pumps Medical, safety and security equipment Garage door openers Access gates Computer, printer, fax, phone and router 14
SECTION 4 – INSTALLATION AND WIRING Extreme care should be taken to protect the transfer switch from drill chips, fillings, and other contaminants when making the cable entry holes and mounting the enclosure to prevent component damage or a future malfunction. This device should be installed in accordance with all local codes, standards and regulations and the latest edition of the National Electrical Code®.

4.1 Standard Mounting Procedures 4 .1.1. As Service Equipment and/or primary Load Center Panel: Models ATS1001D/R, ATS2001D/R or ATS2002R: When using the transfer switch as Service Entrance Equipment, mount the OVATION™ Series ATS as close as possible to the utility meter. NOTE on Models ATS1001R, ATS2001R and ATS2002R only (NEMA Type 3R enclosures): If conduit hub is required, purchase separately from an authorized Siemens distributor, following directions provided.
4.1.2. As a Generator subpanel: Models ATS1001D/R: If using the Ovation™ Series ATS as a generator sub panel, mount the transfer switch as close to the load center as possible. The OVATION™ ATS can be installed on either the left or right side of the load center. If flush-mounting is desired, the OVATION™ ATS can be mounted in the adjacent stud space next to the existing load center. 1. 2. Follow steps 1-2 as above. TURN OFF the main circuit breaker supplying power to existing load center.
4.2 Mounting Procedure for Two Load Centers When the main service is 400A or more and/or 2 or more load centers will be installed, dedicate one load center to non-emergency loads (not connected to generator power) and the 2nd load center as an OVATION™ Model 1001 or 2001D/R load center/transfer switch for generator back-up circuits. Follow 4.1 Standard Mounting Procedures for installation.
NOTE: Not all generators require four control wires to operate. Some may combine the CRANK and ON function in which case the CRANK wire is not required. Additionally, select generators are controlled by a 240VAC signal from the transfer switch. If you need assistance with your particular generator-transfer switch control connection, contact your distributor or Gen/Tran for control wiring instructions. 4.
7. Re-plug cables to Control Module remove in step 2 and PowerPause connector to PowerPause Modules. 8. Re-install Control Module into transfer switch. a. Line up Control Module to breaker bus stabs from where removed in step 1. b. Hold at 30° angle, push onto bus stabs c. Lower outside end flush with enclosure. d. Slide Control Module ½” towards enclosure outside edge, lock into place. e. Install (if required) circuit breaker opposite Control Module. 9.
SECTION 5 – PROGRAMMING THE SYSTEM 5.1 Setting Generator Size If PowerPause™ Load Management Modules are not installed, dial should be set to 25Kw. (Factory default setting is 25Kw). NOTE: Setting dial to 25Kw disables all power management functions even if PowerPause™ Load Management Modules are installed. If any PowerPause™ Load Management modules are installed and connected to manage loads, the generator size needs to be set for proper operation.
5.4 User Interface Display/Control Module Functions Each OVATION™ ATS User Interface Display has five (5) buttons that program and control the automatic transfer switch and control certain generator functions. NOTE: The generator may also have controls that program certain generator features that are NOT programmable from the OVATION™ ATS. See generator Installation and Owners Manual for further generator information. Table 5.4 BUTTON FUNCTION TRANSFER 1.
SECTION 6 –STARTUP AND TESTING Voltages within the transfer switch enclosure present a shock hazard that can cause severe personal injury or death. Use extreme caution to avoid touching electrical contacts when the cabinet door is open or removed. Do not wear jewelry or loose clothing. Stand on a dry, non-conductive surface such as a rubber mat or wooden platform. Improper operation of the generator presents multiple hazards that can cause severe personal injury or death.
