General

Note: Carefully inspect contents for damage after unpacking. Unpack and inspect the generator immediately upon delivery to identify any damage that may have occurred in transit. File any claims for shipping damage as soon as possible with the freight carrier. This is especially important if the generator will not be installed for a period of time.

• This standby generator is ready for installation with a factory-supplied and pre-mounted base pad and has a weather-protective enclosure intended for outdoor installation only.
• If any loss or damage is noted at the time of delivery, have the delivery person note all damage on the freight bill or affix their signature under the consignor’s memo of loss or damage.
• If a loss or damage is noted after delivery, separate damaged materials and contact the freight carrier for claim procedures.
• “Concealed damage” means damage to the contents of a package that was not evident at the time of delivery but was discovered later.

Required tools

• General SAE and metric hand tools
  • Wrenches
  • Sockets
  • Screwdrivers
• Standard electrician’s hand tools
  • Drill and bits for mounting and routing conduits
• T30 star bit for access to customer connections
• 3/16 in hex key for test port on dual shutoff valve
• Manometer for fuel pressure checks
• Meter capable of measuring AC/DC voltage and frequency
• Torque wrenches
• Android or iOS smart device with the latest version of the Field Pro app installed. The app is optimized for use on a smartphone.

Unpacking

Proceed as follows to unpack the generator:

Note: The enclosed keys provided with this generator are intended for service personnel only. Part number 0G66240KEY.

Important: Do not perform the next step until the generator has been transported to the installation site.

Note: Bolts are provided only for shipping purposes and can be discarded after removal.

Opening the lid

Proceed as follows to open the generator lid:

Note: Always verify the lid is unlocked before attempting to lift the lid.

Removing enclosure panels

Generator installation requires removal of the front panel and intake side panel. Remove these panels when necessary. Proceed as follows to remove the panels.

Removing front access panel

See Figure 2-4. Remove front access panel (A) by lifting straight up and out after opening the generator lid.

Note: Always lift the front access panel straight up before pulling it away from the enclosure (B and C). Do not pull the panel away from the enclosure before lifting up (D).

Removing intake side panel

See Figure 2-5. The intake side panel (A) must be removed to access the battery compartment, dual shutoff valve, and sediment trap.

Proceed as follows to remove the intake side panel:

Note: Always lift the intake side panel straight up before pulling it away from the enclosure. Do not pull the panel away from the enclosure before lifting up (C).

Customer connections and loose parts

See Figure 2-6 and Figure 2-7 for customer connections and loose parts locations. Figure 2-9 illustrates parts shipped loose.

Rear connections

Note: The generator is equipped with a connectivity accessory. See the connectivity accessory owner’s manual for further instruction.

Main line circuit breaker (generator disconnect)

See Figure 2-8. This is a 2-pole main line circuit breaker (MLCB) (generator disconnect) (A) rated according to relevant specifications. The generator MLCB (generator disconnect) can be locked in OFF (OPEN) for security. Use an appropriately sized padlock, not included, with a shackle long enough to pass through both lock tabs (B).

Note: Do not leave the generator MLCB (generator disconnect) locked in the OFF (OPEN) position during normal generator operation. Leaving the generator MLCB (generator disconnect) in the OFF (OPEN) position will prevent the generator from powering the structure during a power outage when placed in AUTO mode.

Parts shipped loose

• Keys
• Flexible fuel line
• Battery terminal cover
• Back panel plugs
• Generac Generator Connectivity Accessory, Cellular
• Decal, service entrance warning (not shown)
• Decal, through conductors warning (not shown)
• Decal, generator disconnect (not shown)
• Owner’s and installation manuals (not shown)
• Generac Generator Connectivity Accessory, Cellular manual (not shown)

Generator emergency shutdown switch

All generators are equipped with an external means of shutting down the generator that complies with the latest NEC code requirement. The primary generator shutdown sequence is described in Configuration, startup, and testing.

See Figure 2-10. An emergency shutdown switch (A) is located on the exterior of the generator side panel. This emergency shutdown switch shuts down the generator and disables restarts.

Note: Whenever possible, perform the primary shutdown procedure before disabling the generator with the emergency shutdown switch.

Note: The generator will not start if the emergency shutdown switch is active. The Field Pro app displays “Generator has been stopped via emergency shutdown switch,” and a red LED illuminates and flashes. Press the OFF button for three seconds to clear this condition. The generator can then be placed in AUTO or MANUAL.

Caution: Equipment damage. The emergency shutdown switch should not be used to power down the generator under normal operating circumstances. Doing so will result in equipment damage.
