Power Output

The supplied marketing information states that the DG8500 can deliver up to 7kW of output. Before publishing, confirm whether this figure is:

• Rated continuous power

• Maximum output

• Standby output

• Single-phase output

• Three-phase output

Rated and maximum power should be displayed separately.

Voltage Options

The listed voltage options include 12V, 24V, 220V, and 380V.

These likely represent:

• 12V or 24V DC auxiliary output

• 220V AC single-phase output

• 380V AC three-phase output

Each configuration should clearly identify:

• AC or DC output

• Phase

• Frequency

• Rated current

• Socket type

• Circuit-breaker rating

Air-Cooled Engine

The air-cooling system helps regulate engine temperature during operation without a liquid coolant circuit.

Before publication, confirm:

• Diesel or petrol fuel

• Engine manufacturer

• Engine model

• Displacement

• Cylinder count

• Rated engine output

• Oil capacity

• Fuel consumption

• Recommended engine oil

Electric Start

The 12V DC electric-start system allows the engine to be started using a compatible starter battery.

Confirm whether the starter battery is included in the package.

Low-Oil Shutdown

The low-oil shutdown system is designed to stop the engine when oil pressure or oil level falls below the safe operating range. This can help reduce the risk of engine damage caused by insufficient lubrication.

Users should still inspect the oil level before every operation.

Optional ATS Function

An automatic transfer switch may allow the generator to start and supply power when the main electrical source fails.

Confirm whether the ATS is:

• Included

• Sold separately

• Integrated into the control panel

• Compatible with the selected voltage and phase

• Rated for the generator’s full output current

Portable Open-Frame Design

The open-frame design provides convenient access for inspection and maintenance. Depending on the selected version, wheels and handles may support movement around a worksite.

Because open-frame generators generally produce more audible noise than enclosed silent models, avoid using exact quiet-operation claims without verified noise-test data.

Suitable Applications

The Hiearns DG8500 may be suitable for:

• Construction sites

• Farms and agricultural work

• Workshops

• Small commercial facilities

• Outdoor maintenance

• Emergency backup

• Remote work locations

• Temporary lighting

• Selected pumps and tools

• Mobile service operations

Always confirm the startup and running wattage of connected equipment.

Installation and Operation

Operate the generator outdoors in a dry, well-ventilated location. Keep it away from windows, doors, air intakes, combustible materials, and occupied enclosed spaces.

Professional electrical connection is recommended when supplying a building, distribution board, transfer switch, or fixed equipment.

Maintenance

Routine maintenance may include:

• Engine-oil inspection and replacement

• Air-filter cleaning

• Fuel-filter checks

• Spark-plug or injector inspection, depending on engine type

• Starter-battery testing

• Electrical-terminal checks

• Frame and wheel inspection

• Load testing

Follow the manual supplied with the exact engine configuration.

Certifications

The supplier references CE, ISO 9001:2015, and Euro V certification at company level. Only certifications supported by valid documents for the exact DG8500 model should appear in the final listing.

Important Safety Information

Generators produce carbon monoxide, hot exhaust gases, noise, vibration, and hazardous electrical output.

Never operate the generator indoors, inside a garage, or near occupied spaces. Use qualified professionals for grounding, transfer-switch installation, building connections, and commissioning.

Do not exceed the verified continuous or maximum output.
