Safety
Before using the product for the first time, please read carefully through the safety instructions.
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.
›
The device must be mounted in a fixed position before being connected electrically.
›
Observe all safety regulations and current technical connection specifications of the responsible power
supply company.
›
The device may only be opened and serviced by an authorized electrician.
›
Switch off the grid voltage by turning off the external circuit breakers.
›
Check that all AC and DC cables are completely free of current using a clip-on ammeter.
›
Do not touch the cables and/or terminals/busbars when switching the device on and off.
›
Keep the device closed when it is in operation.
The electrician is responsible for observing all existing standards and regulations. This includes:
Keeping unauthorized persons away from the device/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 jewelery 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 standards.
When working on the PV generator, it is also necessary to switch off the DC voltage with the external DC isolator
switch (e.g. at the string combiner or the KACO DC switchbox) in addition to disconnecting the PV generator from the
grid.
2.1
Intended 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, im-
proper use may cause lethal hazards for the operator or third parties or may result in damage to the device and other
property.
The device is intended for indoor and outdoor applications and may only be used in countries for which it has been ap-
proved or for which it has been released by KACO new energy and the grid operator.
