Preparing for Installation | GenTran ATS2001D, ATS2002R, ATS2001R

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.

3.1Tools and Documents Required

• Electric Drill

• Wire Cutter/Stripper for 18 to 8 gauge AWG wire

• Screwdrivers – Straight Blade and Phillips

• Hammer

• Digital Voltmeter (DVM)

• Stud Finder – For flush mounting in existing construction

• Hole Saw – For flush mount installations

• Installation/Owners Manual for generator being installed to determine correct wiring to the OVATION™ ATS

OTHER ITEMS YOU MAY NEED:

•Anchors and screws to mount transfer switch

•12 VDC battery charger for generator.

•If installing as a sub panel, a new 100 or 200A 2-pole, 240V circuit breaker to mount in main load center – amperage to match utility breaker (see specifications Table I for Utility Main Breaker size – should be manufactured by same as Main load center).

•Standard, Arc-fault, GFCI or Surge protection circuit breakers for branch circuits. If Arc-fault, GFCI or Surge protection circuit breakers are used as the branch circuit protector in the main load center, they MUST be used in the transfer switch. See Section 2.2 for compatible breakers. (Available through most electrical distributors).

•Appropriately sized conduit, wire and fittings to terminate UTILITY MAIN, GENERATOR MAIN source power and branch circuits into the transfer switch

•18 AWG, 3 or 4 conductor, 300V, UL Listed wire (for low voltage signaling between transfer switch and generator).

•An additional Relay Kit (PN: ATSRK) for generator control. See Section 2.1 if required.

3.2 Unpacking/Inspection

After unpacking, carefully inspect the transfer switch for shipping damage. Shipping Damage is not warranted. Contact the freight carrier for claims. Contact your local distributor or Gen/Tran to order missing or replacement parts. Retain paint/plaster shield for use after installation.

3.3 Mounting Location

The OVATION™ Series ATS may be installed outdoors (if NEMA Type 3R enclosure, Models ATS1001R, ATS2001R or ATS2002R) or indoors next to the existing load center or meter base in the house or building. Choose a location that offers a flat, rigid mounting surface capable of supporting the weight of the transfer switch. Avoid locations that are moist, hot, and dusty or contain corrosive substances. Models ATS1001D and ATS2001D may be flush mounted; check that there are no pipes, wires or other obstructions or interferences in the immediate area.

3.4 Planning, Selecting and Prioritizing Your Circuits

1)Provide your installer with a list of the appliances or circuits you want to have powered during a power outage. Examples might include: Refrigerator, freezer, furnace, microwave, lights, well pump, television, garage door opener, aquarium, computer, phone, security system, air conditioner, hot water heater, electric range, pool pump, etc. Review the labels on your load center to determine which circuit breakers these appliances are assigned to. You may need to turn off and on various circuit breakers in your load center to determine the circuits. Circuits/appliances can be selected from two different adjacent load centers. NOTE: You cannot select a single appliance that exceeds the generator output rating. For example, a typical electric range is connected to a 2-pole 50 amp circuit breaker. If your generator’s maximum output rating is only 7500 Watts (30 amps at 240Volts AC), then you cannot select the electric range for back-up power because your generator cannot produce enough power to run this appliance.
