Safety 

 

DANGER

 

Lethal voltages are still present in the connections and cables of the device even after the device has 

been switched off and disconnected!

 

Coming into contact with the lines and/or terminals/busbars in the device can cause serious injury or death. 

› Do not open the device.

 

› The device must be mounted in a fixed position before being connected electrically. 
› Comply with all safety regulations and current technical connection specifications of the responsible 

power supply company. 
› The device is only permitted to be mounted, installed and commissioned by a qualified electrician.  
› Switch off the grid voltage by turning off the external circuit breakers.  
› Do not touch the cables and/or terminals/busbars when switching the device on and off.  
› Check that all AC and DC cables are completely free of current using a clip-on ammeter. 

The electrician is responsible for observing all existing standards and regulations. The following points must be taken into 

account: 

• 

Keep unauthorised persons away from the device and/or system. 

• 

In particular, observe standard 

“Requirements for special types of premises, rooms and installations -  Solar 

photovoltaic (PV) power supply systems” in the respective regionally applicable version. 

• 

Ensure operational safety by providing proper grounding, conductor dimensioning and appropriate protection against 

short circuiting. 

• 

Observe all safety instructions on the product and in this manual 

• 

Switch off all voltage sources and secure them against being inadvertently switched back on before performing visual 

inspections and maintenance 

• 

When taking measurements on the live device: 

– Do not touch the electrical connections 

– Remove all jewellery from your wrists and fingers 

– Ensure that the testing equipment is in safe operating condition 

• 

Modifications to the surroundings of the device must comply with the applicable national and local standards 

• 

When working on the PV generator, in addition to disconnecting this from the grid it is also necessary to switch off the 

DC voltage using the DC isolator switch on the device. 

2.1

 

Proper use 

The device is a transformerless PV inverter which converts the direct current of the PV generator into grid-compatible three-

phase alternating current and then feeds the three-phase alternating current into the public power grid. 
The device is built using state-of-the-art technology and in accordance with the recognized safety rules. Nevertheless, 

improper use may cause lethal hazards for the operator or third parties, or may result in damage to the product and other 

property. 
The device is intended for indoor and outdoor applications and may only be used in countries for which it has been approved 

or for which it has been released by KACO new energy and the grid operator. 
Operate the device only with a permanent connection to the public power grid. The country and grid type selection must be 

commensurate with the respective location and grid type. 
The requirements of the grid operator must be met for grid connection to take place. The permission of the relevant 

authorities may also be required in order to secure authorisation to connection to the grid.

  EU

 

Harmonised document - HD 60364-7-712 (European implementation 

of the IEC standard)

 

The device may only be operated with PV arrays (PV modules and wiring) of protection class II pursuant to IEC 61730, 

application class A. 

 

The name plate must be permanently attached to the product. 
Any other or additional use is not considered proper or intended use and can lead to an annulment of the product guarantee.
