Inverter generator KS 4000iE S ATS Recommendations for use

Inverter generator KS 4000iE S ATS has a built-in ATS unit and can be operated both manually and automatically.

The OFF-RUN rotary switch on the right side of the generator combines the fuel tap, the switch for the internal 12V power supply and the ignition switch. When the generator is not in use, it should remain OFF so that the lithium battery installed in the generator does not discharge. The generator comes with a disconnected battery, which must be connected under the left side cover when first used. The battery is recharged by the internal charging module as soon as the generator is running or the 230V voltage comes to the MAINS INPUT (regardless of the position of the rotary switch).

The MAINS INPUT 230V connection is monitored as soon as you set the rotary switch to RUN and switch the ATS SWITCH to ON. If the 230V voltage at the MAINS INPUT fails, the ATS controller starts the generator and switches its 230V output sockets to the inverter module.

The KS 4000iE S ATS has 2 x 230V sockets, which are switched differently depending on the version of the generator.

KS 4000iE S ATS Version 1 for individual electricity consumers only

The two 230V sockets are active both when operating from the MAINS INPUT and when operating from the generator.

When operated from the MAINS INPUT, the two 230V sockets supply the same system (IT, TN, TT) as MAINS INPUT. The generator must be earthed in TT and TN systems with a copper cable 6-10 mm² (depending on local regulations) by connecting its earth screw to the same earth bar to which the MAINS 230V power source is earthed.

The two outlets after switching power to the generator supply only IT system without the grounded neutral conductor. Regulations and protective measures for the IT system must be observed.

With this version of the generator it is possible to supply electricity consumers that can work both in the TN and in the IT system. It is not possible to supply the house completely in automatic mode!

KS 4000iE S ATS Version 2 for individual electricity consumers or home backup

The right 230V socket is active both when operating from the MAINS INPUT and when operating from the generator.

The right 230V socket when operating from the MAINS INPUT the same system (IT, TN, TT) as MAINS INPUT. The generator must be earthed in TT and TN systems with a copper cable 6-10 mm² (depending on local regulations) by connecting its earth screw to the same earth bar to which the MAINS 230V power source is earthed.

The left socket is connected to the output of the inverter module and is active only when the generator is running. If necessary, a TN system can be built with the generator. The neutral conductor of the generator inverter module can be grounded externally via the left socket. The inverter module has built-in electronic overload and short-circuit protection and the left 230V socket is protected as a result.

The left socket, which is only active when the generator is in operation, enables use in systems where the 230V is not always required, but only when the main power supply fails. The MAINS INPUT can monitor the main power supply.

With this version, an automatic backup power supply for the whole house, office, etc. would also be possible.

The rated power of the generator is 3.5 kW and can also be taken from one of the two 230V sockets.
