2. Safety Information

Operating a generator can be dangerous if proper safety precautions are not followed. Read and understand all safety warnings before operating this equipment.

• Carbon Monoxide Hazard: Generators produce carbon monoxide, a colorless, odorless, poisonous gas. Operate the generator ONLY outdoors and far away from windows, doors, and vents. Never operate indoors or in enclosed spaces.
• Electrical Shock Hazard:
  • Do not operate the generator in wet conditions.
  • Ensure the generator is properly grounded before use.
  • Never connect the generator directly to a building's electrical system without a qualified electrician and an approved transfer switch. This can cause backfeed, which is dangerous for utility workers.
• Fire Hazard:
  • Diesel fuel is flammable. Store fuel in approved containers and in a well-ventilated area.
  • Do not refuel the generator while it is running or hot. Allow it to cool down.
  • Keep flammable materials away from the generator during operation.
• Burn Hazard: Engine components become very hot during operation. Avoid contact with hot surfaces.
• Noise Hazard: Wear hearing protection when operating the generator for extended periods.
• Maintenance Safety: Disconnect the battery and allow the generator to cool before performing any maintenance.

5. Setup

Proper setup is crucial for safe and efficient operation.

1. Unpacking and Inspection: Carefully remove the generator from its packaging. Inspect for any shipping damage. Report any damage to your dealer immediately.
2. Placement:
   • Place the generator on a firm, level surface.
   • Ensure adequate ventilation. The generator must be operated outdoors, far from any building openings (windows, doors, vents) to prevent carbon monoxide buildup.
   • Maintain at least 1 meter (3 feet) of clear space around all sides of the generator.
3. Fueling:
   • Use only clean, fresh diesel fuel.
   • Ensure the generator is off and cool before refueling.
   • Do not overfill the fuel tank. Leave space for expansion.
   • Wipe up any spilled fuel immediately.
4. Engine Oil:
   • Check the engine oil level using the dipstick.
   • Add recommended diesel engine oil if the level is low. Refer to the engine manual for specific oil type and capacity.
5. Coolant:
   • Check the coolant level in the radiator.
   • Top up with appropriate engine coolant if necessary.
6. Battery Connection: Connect the battery terminals (if not pre-connected), ensuring correct polarity (positive to positive, negative to negative).
7. Grounding: Connect the generator to a proper earth ground using a heavy-gauge wire. This is a critical safety step to prevent electrical shock.
8. Load Connection:
   • For direct loads, connect appliances or power distribution units to the appropriate 230V or 400V outlets.
   • For ATS (Automatic Transfer Switch) operation, connect the generator to the ATS panel according to the ATS manufacturer's instructions.
   • Ensure the total load does not exceed the generator's rated capacity.

6. Operating Instructions

Follow these steps for safe and effective operation of your generator.

6.1. Pre-Start Checks

• Verify fuel level.
• Check engine oil level.
• Confirm coolant level.
• Ensure all electrical loads are disconnected from the generator before starting.
• Check that the generator is properly grounded.

6.2. Starting the Generator (Electric Start)

1. Turn the main circuit breaker on the generator to the "OFF" or "OPEN" position.
2. Insert the key into the ignition switch.
3. Turn the key to the "START" position and hold until the engine starts. Do not crank for more than 5 seconds at a time. If the engine does not start, wait 10 seconds before trying again.
4. Once the engine starts, release the key, and it will return to the "RUN" position.
5. Allow the generator to warm up for a few minutes before applying any load.
6. Once stable, turn the main circuit breaker to the "ON" or "CLOSED" position. You can now connect your loads.

6.3. Operating the Generator

• Load Management: For optimal performance and longevity, distribute the load symmetrically across the phases for three-phase operation. Avoid overloading the generator.
• Monitoring: Periodically check the control panel for voltage, frequency, and any warning indicators.
• Refueling: Never refuel while the generator is running or hot. Shut down the generator and allow it to cool before adding fuel.

6.4. Stopping the Generator

1. Disconnect all electrical loads from the generator.
2. Turn the main circuit breaker to the "OFF" or "OPEN" position.
3. Allow the generator to run for a few minutes without load to cool down.
4. Turn the ignition key to the "OFF" position to shut down the engine.
5. Remove the key for security.
