15kVA Aico Japan Diesel Generator with ATS – Three-Phase Automatic Backup Power

The 15kVA Aico Japan Diesel Generator with ATS is designed to provide dependable three-phase standby electricity for commercial, agricultural, institutional, and light industrial premises. Its 15kVA rated output makes it suitable for supporting compatible three-phase machinery, pumps, refrigeration equipment, workshop tools, lighting systems, office equipment, and other essential electrical loads.

The included Automatic Transfer Switch monitors the utility supply and initiates automatic generator operation when a power outage occurs. Once the generator stabilizes, the ATS transfers the connected load to backup power and returns it to the utility supply when stable mains electricity is restored.

This generator is a practical solution for businesses and facilities that require automatic power continuity with minimal manual intervention. Correct load assessment and professional installation are essential, particularly where equipment has high starting currents or uneven phase loading.

Installation Guidelines

• Install the generator on a strong, level concrete foundation.
• Place it in a secure and adequately ventilated location.
• Direct exhaust gases away from occupied areas and air intakes.
• Provide adequate clearance for cooling and maintenance.
• Properly earth the generator and the connected electrical system.
• Have the ATS installed by a qualified three-phase electrician.
• Confirm the correct phase sequence before connecting equipment.
• Distribute single-phase loads evenly across the three phases.
• Ensure the ATS and protective devices are correctly rated.
• Protect the generator installation from flooding and standing water.
• Complete a professional load assessment before commissioning.

Operating Guidelines

• Check fuel and engine oil before operation.
• Confirm that the generator is ready before selecting automatic mode.
• Keep the starting system in good condition for automatic operation.
• Allow the generator to stabilize before the ATS applies the load.
• Monitor voltage and loading across all three phases.
• Avoid excessive phase imbalance.
• Do not exceed the generator’s rated output.
• Test the automatic transfer function periodically.
• Investigate alarms, unusual vibration, smoke, or unstable power immediately.

Care and Maintenance

• Check engine oil regularly.
• Use clean diesel from a reliable supplier.
• Inspect the fuel system for leaks.
• Keep the starting battery charged and its terminals clean.
• Clean ventilation openings and remove accumulated dust.
• Inspect cables, terminals, and protective devices periodically.
• Run the generator regularly when kept in standby.
• Test the ATS under controlled conditions.
• Replace oil and filters according to the service schedule.
• Have phase loading checked periodically.
• Keep the generator area clean, dry, and well ventilated.

Do’s and Don’ts

Do

• Use a qualified electrician for installation.
• Confirm the phase sequence before commissioning.
• Balance connected loads across the three phases.
• Test the ATS regularly.
• Properly earth the generator.
• Operate within the 15kVA rated capacity.
• Schedule preventive maintenance.
• Check the starting demand of motors and pumps.

Don’t

• Do not overload the generator.
• Do not connect it directly to the mains without a transfer system.
• Do not operate it in an enclosed, occupied space.
• Do not refuel while the generator is running or hot.
• Do not bypass or modify the ATS wiring.
• Do not allow severe load imbalance between phases.
• Do not block cooling or exhaust openings.
• Do not connect large motors without checking their starting current.

Compatibility

The generator is suitable for compatible three-phase equipment and installations such as:

• Three-phase water pumps
• Workshop machinery
• Commercial refrigeration systems
• Small production equipment
• Agricultural processing machines
• Three-phase motors
• Commercial lighting circuits
• Office and communication equipment
• Security and surveillance systems
• Mixed three-phase and balanced single-phase loads

Compatibility depends on the equipment’s running demand, starting current, phase requirements, and the total load connected to the generator.

Frequently Asked Questions

What is the generator’s rated output?

The generator has a rated output of 15kVA.

Is it single phase or three phase?

This model provides a three-phase electrical output.

Does it come with an ATS?

Yes. It is supplied with an Automatic Transfer Switch for automatic backup operation.

What happens when mains electricity fails?

The ATS detects the outage, initiates generator startup, and transfers the connected load after the generator stabilizes.

Will it return automatically to mains power?

Yes. A correctly installed ATS transfers the load back when stable utility electricity is restored.

Can it power three-phase motors?

It can support compatible three-phase motors, but the motor’s starting current must be assessed before connection.

Can single-phase equipment be connected?

Single-phase circuits may be connected through a properly designed distribution system, but the loads must be balanced across the three phases.

Is it suitable for a residential home?

A three-phase generator is mainly suitable for properties with a three-phase electrical installation. It should not be purchased for a single-phase property without professional assessment.

Does it require professional installation?

Yes. Professional installation is essential for correct phase sequence, earthing, protection, ATS integration, and load balancing.
