Safety Section 1 Safety Introduction Thank you for purchasing a Generac Power Systems Inc. product. This unit has been designed to provide high performance, efficient operation, and years of use when maintained properly. WARNING Indicates a hazardous situation which, if not avoided, could result in death or serious injury. (000002) Read This Manual Thoroughly CAUTION WARNING Consult Manual. Read and understand manual completely before using product.
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 Unpacking Carefully unpack the transfer switch. Inspect closely for any damage that might have occurred during shipment. The purchaser must file with the carrier any claims for loss or damage incurred while in transit. Check that all packing material is completely removed from the switch prior to installation.
General Information Transfer Switch Data Decal Smart A/C Module (SACM) A data decal is permanently affixed to the transfer switch enclosure. Use this transfer switch only with the specific limits shown on the data decal and on other decals and labels that may be affixed to the switch. This will prevent damage to equipment and property. When requesting information or ordering parts for this equipment, make sure to include all information from the data decal.
General Information Smart Management Module (SMM) (50 amp and 100 amp sold separately) Application Considerations Any loads, including central air conditioners, can be managed using a Smart Management Module (SMM). The system can accommodate up to eight individual SMMs. NOTE: SMMs are self-contained and have individual built-in controllers. Generator overload condition is determined by generator frequency.

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. Install the transfer switch as close as possible to the electrical loads that are to be connected to it. Mount the switch vertically to a rigid supporting structure. To prevent switch distortion, level all mounting points. If necessary, use washers behind mounting holes to level the unit.
Installation Connecting Power Source and Generator Power Supply NOTE: If aluminum conductors are used, apply corrosion inhibitor to conductors. After tightening terminal lugs, carefully wipe away any excess corrosion inhibitor. 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) N1 Installation and interconnection diagrams are provided in this manual.
Installation Connecting SACM CAUTION Equipment damage. Verify all conductors are tightened to the factory specified torque value. Failure to do so could result in damage to the switch base. (000120) Connecting Start Circuit Wires Control system interconnections consist of N1, N2, and T1, and leads 23, 0, and 194 (see Figure 3-3). NOTE: Generac Type TC-ER-JP power and control tray cable can be installed as permitted by the 2017 NEC. Type TC-ER-JP cable contains color-coded power and control conductors.

Installation Auxiliary Contact Fault Current Label See Figure 3-4. If desired, there is one normally-closed Auxiliary Contact (A) on the transfer switch to operate customer accessories, remote advisory lights, or remote annunciator devices. A suitable power source must be connected to the common terminal. If needed, an extra auxiliary contact can be added. See Figure 3-5.
Installation Installing PWRview Antenna Connecting PWRview CTs 1. See Figure 3-6. Measure and create a 1/2 inch knockout location (A) for antenna, preferably on the bottom of the enclosure at least 6 inches from any metal conduit. Avoid top mounting the antenna for outdoor applications to minimize the chance of water ingress. 1. Clamp one of the included CTs to the subpanel supply line T1. "SOURCE THIS SIDE" marking must face transfer switch contactor (away from customer load). 2.
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 Generator 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 generator (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 5. Set the generator main circuit breaker to ON or CLOSED. The generator now powers all LOAD circuits. Check generator operation under load as follows: • Turn on electrical loads to the full rated wattage/amperage capacity of the generator. DO NOT OVERLOAD. • With maximum rated load applied, check voltage and frequency across transfer switch terminals E1 and E2. Voltage should be greater than 230 VAC (240 VAC system); frequency should be greater than 59 Hz.
Operation 3. Set generator to AUTO mode at the controller. SACM Fuse Service 4. Generator will start and run. Allow generator to run and warm up for a few minutes. See Figure 4-2. A fuse removal and installation tool (A) is included in the SACM housing. 5. Set generator MLCB (generator disconnect) to ON (CLOSED). 6. Set utility MLCB to ON (CLOSED). The system now operates in automatic mode. Preparing for Maintenance DANGER A Automatic start-up.
Operation PWRview Monitor Reset 1. See Figure 4-3. If a manual reset of the PWRview monitor is required, turn the PWRview reset toggle switch (A) (located on the inside cover) to the OFF position for at least 30 seconds. 2. Toggle the PWRview reset to the ON position. The PWRview monitor will go through the startup procedure and connect to the Wi-Fi® network. 3. Verify the PWRview monitor has establlished communication with the Wi-Fi network through the PWRview Installer app on your smartphone.
