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!
Severe injuries or death may occur if the cables and/or terminals/busbars in the device are touched.
1. Comply with all safety regulations and current technical connection specifications of the responsible power
supply company.
2. The device is only permitted to be opened or serviced by a qualified electrician.
3. Switch off the grid voltage by turning off the external circuit breakers.
4. Do not touch the cables and/or terminals/busbars when switching the device on and off.
5. Keep the device closed when in operation.
The electrician is responsible for observing all existing standards and regulations. The following applies:
– Keep unauthorised persons away from the device and/or system.
– In particular, making sure that the locally applicable version of the standard
1
"Requirements for special installations
or locations – solar photovoltaic (PV) power supply systems" is observed.
– Ensure operational safety by providing proper grounding, conductor dimensioning and appropriate protection against
short circuiting.
– Observe all safety instructions on the product and in these operating instructions.
– 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 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-com-
patible 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. Never-
theless, 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 se-
lection 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 rel-
evant authorities may also be required in order to secure authorisation to connection to the grid.
