GENERAL INFORMATION

The ATS 501 is designed to automatically switch the on board 120 or 240 volt appliances to generator power when the generator is activated.
No longer do you need to go outside, remove the shoreline cord from the pole and plug it into the generator receptacle. Likewise in marine applications you simply start the generator and the ATS501 will switch the loads for you.

OPERATION

After the ATS 501 is installed using one of the typical installations shown in this manual, it will be ready for years of trouble free service. Operation is automatic and is maintenance free.

FROM SHORELINE:
To operate appliances from shoreline power, simply plug in the shoreline cord to the power pole at the campground or dock. The ATS 501 automatically connects all AC Appliances to shoreline power.

FROM GENERATOR:
To operate appliances from on board generator simply start the generator.
After a typical 20 second delay to allow the generator to stabilize the ATS 501 will engage, transferring all 120 or 240-volt appliances connected to the ATS 501 load terminals to the generator.

AUXILIARY CONTACT OPERATION

The ATS 501 RV line generator switch when connected as in the typical installation II shown in this manual may control other equipment in your vehicle. The auxiliary contacts are rated for 30 A @ 120 VAC operation and will switch other loads as the ATS 501 switches from shore power to generator. These contacts are supplied as non-energized dry contacts.

MOUNTING LOCATION

The ATS 501 series may be installed in any position, leaving room for routing shoreline, generator and load conductors. To minimize voltage drop in the wiring the transfer switch should be located as close to the generator and shoreline cord entrance as practical.
DO NOT install the ATS 501 series in the generator compartment.
The ATS 501 series is not ignition protected and should not be mounted in the same compartment as batteries or flammable materials such as gasoline. It may be mounted in the cabin or living area or a basement compartment, but is not suitable for outside locations.
The ATS 501 should be installed by a qualified electrician.
