OPERATING SAFETY
Before using the unit, be sure you read and understand all of the instructions. This equipment was
designed for specific applications; DO NOT modify or use this equipment for any application other than
which it was designed for. Equipment operated improperly or by untrained personnel can be dangerous.
Read the operating instructions and familiarize yourself with the location and proper use of all instruments
and controls. Inexperienced operators should receive instruction from someone familiar with the equipment
before being allowed to operate or set up the unit. The following points should be practiced at all times:
• The area immediately surrounding the unit should be dry, clean, and free of debris.
• Position and operate the unit on a firm, level surface.
• DO NOT start a unit in need of repair.
• If the unit is equipped with a frame grounding stud, follow any local, state, and National Electrical
Code (NEC) guidelines when connecting.

Safety
ENGINE SAFETY
Internal combustion engines present special hazards during operation and fueling. Failure to follow the
safety guidelines described below could result in severe injury or death. Read and follow all safety warnings
described in the engine operator's manual. A copy of this manual was supplied with the unit when it was
shipped from the factory.
• DO NOT run engine indoors or in an area with poor ventilation. Engine exhaust contains carbon
monoxide, a deadly, odorless and colorless gas which, if inhaled, can cause nausea, fainting or death.
Make sure engine exhaust cannot seep into closed rooms or ventilation equipment.
• DO NOT touch or lean against hot exhaust pipes or engine components.
• DO NOT clean air filter with gasoline or other types of low flash point solvents.
• DO NOT operate the unit without a functional exhaust system.
• Prolonged exposure to sound levels in excess of 85 dB(A) can cause permanent hearing loss. Wear
hearing protection when working around a running engine.
• Batteries contain sulfuric acid which can cause severe injury or death. Sulfuric acid can cause eye
damage, burn flesh or eat holes in clothing. Protective eye wear and clothing are necessary when
working on or around the battery. Always disconnect the negative (-) battery cable from the
corresponding terminal before performing any service on the engine or other components.
SERVICE SAFETY
All service work must be performed by qualified personnel who are familiar with the equipment. Only a
qualified electrician should troubleshoot or repair electrical problems occurring in this equipment. Follow the safety guidelines described below to prevent hazardous situations which could result in severe
injury or death.
• DO NOT wash the unit with high pressure hoses, power washers, or steam cleaners. Water may
collect in the unit, causing damage to electrical parts.
• ALWAYS use extreme caution when servicing this unit in damp conditions. Do not service the unit if
your skin or clothing is wet. Do not allow water to collect around the base of the unit.
• Replace all missing and hard to read decals. Decals provide important operating instructions and
warn of dangers and hazards.
TOWING SAFETY
Towing a trailer requires care. Both the trailer and vehicle must be in good condition and securely fastened
to each other to reduce the possibility of an accident. Some states require that large trailers be registered
and licensed. Contact your local Department of Transportation office to check on license requirements for
your particular unit.
• Verify the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's
Gross Vehicle Weight Rating (GVWR).
• Check trailer tires for wear and proper inflation.
• DO NOT tow trailer using defective parts. Inspect the hitch and coupling for wear or damage.
• Verify the trailer hitch and the coupling are compatible. Make sure the coupling is securely fastened
to the vehicle.
• Verify directional and brake lights on the trailer are connected and working properly.
• Verify wheel lug nuts are present and tightened to the specified torque.
• Maximum recommended speed for highway towing is 45 mph (72 km/h). Recommended off-road
towing speed is 10 mph (16 km/h) or less, depending on terrain.
2 MMG330DI4-480DI4 Operating Manual 33797 C
Safety
• When towing, maintain extra space between vehicles and avoid soft shoulders, curbs and sudden
lane changes. Practice turning, stopping and backing up in an area away from heavy traffic prior to
transporting the unit.
• Wipe the coupler clean and apply fresh grease each time the trailer is towed to eliminate squeaking.
REPORTING TRAILER SAFETY DEFECTS
If you believe your trailer has a defect which could cause a crash or could cause injury or death, you should immediately
inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Generac Mobile Products
LLC.
If NHTSA receives similar complaints, it may open an investigation; and if it finds that a safety defect exists in a group
of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in an individual
problem between you, your dealer, or Generac Mobile Products LLC.
To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-888-327-4236 (TTY:1-800-424-9153),
go to http://www.safercar.gov; or write to:

POWER ZONE™ CONTROLLER
The Power Zone™ controller is an auto start controller that monitors the unit and indicates operational status and
fault conditions. The controller can be programmed to automatically start or stop on based time schedule, fault
condition, or load demand.
The controller constantly monitors vital generator and engine functions for a number of pre-programmed alarm and
fault conditions. When a fault condition occurs, the engine can be shut down automatically and the main display will
show the fault that caused the shut down; to resume operation, the fault condition must be resolved.
This controller also records a history of unit performance which may be viewed at any time and will not be lost when
the controller is powered down.

General Information
Navigation Buttons
These buttons are used to navigate and interact with the Power Zone™ controller screens. Pressing any directional
arrow (“▲”, “►”, “▼”, “◄”) while on any of the operator screens will open the maintenance screens, and navigate
the tabs and pages within the maintenance screens. The Enter “” button is used to select menus, confirm alarms,
and confirm altered settings.
Control Power Switch
Use this switch to start up and shut down the Power Zone™ controller. This switch should not be turned off when
the unit is running.
Engine Start
Pressing the Engine Start “I” button while the controller is in “Manual Mode” will start the unit, provided there are no
shutdown errors, and the engine satisfies the start status. If the controller is in “Auto Mode”, the engine start button
has no effect.
Engine Stop/Reset
Pressing the Engine Stop/Reset “O” button will shut down the unit and put the controller into Stop Mode, whether in
“Manual Mode” or “Auto Mode”.
CAUTION
In case of an emergency, always press the “EMERGENCY STOP” switch located on the
side of the unit to stop the engine immediately. The Engine Stop/Reset “O” button may delay
the engine shutdown if stop faults exist.
To prevent damage to the generator and connected equipment, remove all loads from the
generator by opening all circuit breakers (turn to “OFF/O”) before pressing the Engine Stop/
Reset “O” button.
OPERATOR SCREENS
The operator screens display the most relevant and critical information an operator will need to properly configure
and utilize a unit. From these four screens the operator can access engine, generator and power transmission
information necessary to operate the unit under normal conditions.
Home Screen
The Home screen is the default screen of the controller and will display after the controller is powered up and the
unit management software is loaded. It displays a live readout of the kW meter, percent of load used (gauge), selected
phase, volts and amps being produced by the generator, and the fuel level with time until empty. The controller will
automatically return to this screen from any other screen after a period of inactivity.
