4.11 ATS Connections
The generator is equipped with an Automatic Transfer Switch (ATS) plug on the left side of
the control panel. The customer can select an appropriate automatic transfer switch (ATS)
and connect it to the generator.

Connect the wire between the generator set and ATS plug.

Connect the wires between the generator main wiring terminals
and the ATS wiring terminals.

Connect the wires between the mains supply wiring terminals
and the ATS wiring terminals.

Connect the wires between the load wiring terminals and the
ATS wiring terminals.
The ATS is controlled by the PLC module which can monitor the incoming AC mains supply. If
the mains supply is satisfactory the load is run through the ATS and the generator will not
run. On the contrary the generator will run if the mains power is abnormal.
THE ATS LOCATION IS IMPORTANT, THE FOLLOWING MUST BE OBSERVED:

The ATS should be located inside the building near the main switchboard.


When the ambient air is above 40°C (104°F), fuses and circuit breakers must be
de ‐ rated. Allow adequate working space around the transfer switch.

Never install control wires in the same conduit with mains wiring.

ATS and all equipment must be installed in accordance with relevant local and
national codes and regulations.

If the ATS is mounted outside, it must be protected from the environment.

Do not mount the ATS on the generator.

