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. See product label on door/cover for list of hubs available. See product label on door/cover for conduit hub part numbers. Punch appropriate size hub hole in Model ATS2002R enclosure, all other enclosures have
1.Remove the cover and dead front from the OVATION™ Series ATS. Hold it level against the mounting surface, mark and drill the mounting holes. If flush mounting, locate between appropriate studs and secure properly. Required knockouts may be removed prior to mounting.
2.Remove the cables plugged into the Control Module. Care should be taken in unplugging these cables as they have a securing ‘latch’. Forcing the cables loose will damage the connectors. Observe that the power mating plug J6 is installed in the connector. Unplug it and set aside for future use in Section 4.3.
3.To avoid debris and metal chips from entering the Control Module, cover or remove

4.Cover or remove the installed circuit breakers and associated mechanisms from dust and metal chips.
5.Fasten the OVATION™ Series ATS to mounting surface with appropriate fasteners (not provided); use spacers behind the mounting holes to ensure the enclosure is plumb and not distorted.
6.Install appropriately sized Utility and Generator source wire into the enclosure and use proper fittings to secure and provide proper protection to conductor insulation. (For more information on wire size and ampacity ratings, see NEC Article 310, Table 310.16). The OVATION™ Series ATS have been UL Listed for use with Copper or AL wire.
7.Connect the X and Y source wire to the appropriate circuit breaker terminals marked “UTILITY MAIN” or “GENERATOR MAIN”. If optional PowerPause™ Load Management Modules are going to be installed, each X and Y generator source wire should pass through the hole of current transformer on the current sense cable supplied with PowerPause Load Management module kit BEFORE connection to GENERATOR MAIN circuit breaker. Route current sense cable as shown in diagrams 4.1 – 4.3, and plug P4 into J4 on Control Module. Ensure UTILITY and GENERATOR SENSE lead wires located in UTILITY and GENERATOR MAIN circuit breaker lugs remain in the UTILITY and GENERATOR MAIN lugs when tightening the UTILITY and GENERATOR MAIN source wire. When AL conductors are used, the application of a
8.If transfer switch is used as Service Equipment:
a.ATS1001D/R: Tighten “NEUTRAL BOND” green screw at top of right hand neutral bar into enclosure.
b.ATS2001D/R: Install “NEUTRAL BOND” kit provided, following Installation Instructions included with kit.
c.ATS2002R: Connect provided “NEUTRAL BOND” pigtail located on neutral buss to ground bus.
Apply provided “Service Disconnect” label next to the UTILITY MAIN circuit breaker on deadfront.
9.Install branch circuit breakers and wiring as required.
10.If transfer switch is installed in new construction, affix provided paint/plaster shield to transfer switch to keep interior clean. Remove when all wallboard and painting is completed and proceed to next step.
11.Install and wire the correct type and rating of compatible branch circuit breakers (see Section 2.2), complying with the product label wiring diagram for each branch circuit. See the branch circuit breaker markings for correct wire size and tightening torque requirements.
12.Ensure all wires are clear of the actuator/motor module and mechanical interlocks.
13.Reinstall all components and cables if removed, and proceed to Section 4.2.
