Safety Section 1: Safety Introduction Safety Rules Thank you for purchasing a Generac product. This unit has been designed to provide high performance, efficient operation, and years of use when maintained properly. The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed to the unit are, therefore, not all inclusive.
Safety Electrical Hazards DANGER DANGER Electrocution. High voltage is present at transfer switch and terminals. Contact with live terminals will result in death or serious injury. (000129) DANGER Equipment malfunction. Installing a dirty or damaged transfer switch will cause equipment malfunction and will result in death or serious injury. (000119) WARNING Electrocution. Water contact with a power source, if not avoided, will result in death or serious injury. (000104) DANGER Electric shock.
Safety General Hazards DANGER DANGER Electrical backfeed. Use only approved switchgear to isolate generator from the normal power source. Failure to do so will result in death, serious injury, and equipment damage. (000237) DANGER Electrocution. In the event of electrical accident, immediately shut power OFF. Use non-conductive implements to free victim from live conductor. Apply first aid and get medical help. Failure to do so will result in death or serious injury. (000145) WARNING Electrocution.

General Information Section 2: General Information Applications The PWRcell Automatic Transfer Switch (ATS) can be utilized with a PWRcell Energy Storage System (ESS) alone, or in conjunction with a Generator. When used with a PWRcell ESS alone, it enables the entire home to be powered from the ESS, within the limits of it’s power capacity. To ensure your PWRCell is protected from being overloaded, see section, Load Management Options.
General Information Utility Service Circuit Breaker (if equipped) The utility service and generator disconnect circuit breakers for 100 amp models are: • • • • • • Type BQ, 2-pole 10,000 A/C 120/240VAC, 100A 50/60 Hertz Wire range: #1 - #8 AWG (Cu/Al) Transfer Switch Enclosure The standard switch enclosure is a National Electrical Manufacturer’s Association (NEMA) and UL 3R type.
General Information illuminate when a load is connected and powered. See Figure 2-2. The controller has a test button (C) used to simulate an overload condition. This button operates even when the transfer signal is inactive. C Application Considerations An overload condition is determined by the PWRcell inverter frequency while the inverter is in island mode. Loads are managed and de-energized when frequency is less than 58 Hz for three seconds or less than 50 Hz for ½ second (for 60 Hz systems).
General Information Current Transformers Current Transformers are provided with the PWRcell Inverter and allow the inverter to measure the flow of power to and from the home. The PWRcell ATS Controller provides connections for these CTs (A), and for CT measurements to be sent back to the inverter (B). B A 011166 Figure 2-4.
Installation Section 3: Installation Introduction to Installation This equipment has been wired and tested at the factory. Installing the switch includes the following procedures: • • • • • • Mounting the enclosure. Connecting power source and load leads. Connecting the PWRcell inverter control conductors. Installing the current transformers. Connecting the PWRcell ATS Controller. Configuring the inverter. NOTE: Inner panel (E) is ONLY on Service Entrance Rated Models. 5.
Installation D J A H B G F E C 004397 Figure 3-1. Open Enclosure Connecting Utility and Standby Power Sources DANGER Electrocution. Turn utility and emergency power supplies to OFF before connecting power source and load lines. Failure to do so will result in death or serious injury. (000116) Installation and interconnection diagrams are provided in this manual. NOTE: All installations must comply with national, state and local codes.
Installation cables or conduits entering above the level of uninsulated live parts shall use fittings listed for use in wet locations as required by 312.2 in the NEC. NOTE: If aluminum conductors are used, apply corrosion inhibitor to conductors if required by the aluminum conductor manufacturer. After tightening terminal lugs, carefully wipe away any excess corrosion inhibitor. N1 B N2 E1 E2 N1 N2 T2 T1 A A 011266 Figure 3-3.

Installation Connecting the Current Transformer (CTs) Manual Override Button DANGER Connect the CTs as shown in Table 3-1 below. Clamp CT1 and CT2 around the wires connected to T1 and T2, respectively. Electrocution. Only authorized personnel should access transfer switch interior. Transfer switch doors should be kept closed and locked. Failure to do so will result in death or serious injury. (000213) Table 3-1.
Installation Fault Current Label See Figure 3-8. A Fault Current Identification Label is provided in the bag containing the unit Owner’s Manual and transfer switch manual operating handle. The 2017 NEC requires that the short-circuit current rating of the transfer equipment, based on the type of overcurrent protective device protecting the transfer equipment, be field marked on the exterior of the transfer equipment.

Operation Section 4: Operation Functional Tests and Adjustments Following transfer switch installation and interconnection, inspect the entire installation carefully. A competent, qualified electrician should inspect it. The installation should comply strictly with all applicable codes, standards, and regulations. When absolutely certain the installation is proper and correct, complete a functional test of the system. CAUTION Equipment damage.
Operation Close to Inverter Source Side Before proceeding, verify the position of the switch by observing the position of the manual operation handle in Figure 4-1. If the handle is DOWN, the contacts are closed in the inverter (standby) position. No further action is required. If the handle is UP, proceed with Step 1. 1. With the handle inserted into the movable contact carrier arm, move the handle DOWN. Be sure to hold on to the handle as it will move quickly after the center of travel. 2.
Operation 2. Verify proper operation of the system as outlined in the appropriate installation and owner’s manuals. 3. Educate the end-user on the proper operation, maintenance and service call procedures. PWRcell ATS Controller Fuse Service See Figure 4-2. A fuse removal and installation tool (A) is included in the controller housing. NOTE: The Utility Power Circuit Breaker in the transfer switch must be turned OFF to simulate a utility outage.
