3Description of the device
3.1 Mode of operation
The device converts the DC voltage generated by the PV-modules into AC voltage and feeds this into the power
grid. The starting procedure begins when there is sufficient sunlight and a specific minimum voltage is present
in the device. The feed-in process begins once the PV generator has passed the insulation test and the grid
parameters are within the requirements imposed by the grid operator for a specific monitoring time. If, as it
gets dark, the voltage drops below the minimum voltage value, feed-in mode ends and the device switches off.

NOTE
If a residual current circuit breaker is necessary due to the installation specification, a type A residual current
circuit breaker must be used.
If the type A is used, the insulation threshold must be set to greater than/equal to (≥) 200kOhm in the “DC
parameters” menu Configuration via web user interface.
For questions regarding the appropriate type, please contact the installer or our KACO new energy customer
service.
6.6 Connect PV generator to device
6.6.1 Checking the PV generator for a ground fault
DANGER
Risk of fatal injury due to electric shock!
Severe injury or death will result if the live connections are touched. When there is sunlight present on the PV
generator, there is DC voltage on the open ends of the DC cables.
1. Activate the connection power at the switchbox or string combiner with the DC isolator switch.
2. The DC connection is intended exclusively for PV generators. Other sources fall within the scope of im-
proper operation (e.g. batteries).
3. Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
4. Avoid short circuits.
5. Do not connect any strings with a ground fault to the device.
Ensure that there is no ground fault
1. Measure the DC voltage between the protective earth (PE) and the positive cable of the PV generator.
2. Measure the DC voltage between the protective earth (PE) and the negative cable of the PV generator.
ðIf stable voltages can be measured, there is a ground fault in the DC generator or its wiring. The ratio between
the measured voltages gives an indication as to the location of this fault.
3. Rectify any faults before taking further measurements.
4. Measure the electrical resistance between the protective earth (PE) and the positive cable of the PV generator.
4When it is connection to a TN-C grid, the PEN grounding cable is connected to the ground earthing point.

5. Measure the electrical resistance between the protective earth (PE) and the negative cable of the PV generator.
ðIn addition, ensure that the PV generator has a total insulation resistance of more than 2.0 MOhm, since the
device will not feed in if the insulation resistance is too low.
6. Rectify any faults before connecting the DC generator.
6.6.2 Designing the PV generator
CAUTION
Damage to components due to faulty configuration
In the expected temperature range of the PV generator, the values for the no-load-voltage and the short circuit current
must never exceed the values for Udcmax and Iscmax in accordance with the technical data.
1. Observe limit values in accordance with the technical data.
NOTE
Type and configuration of the PV modules.
Connected PV modules must be dimensioned for the DC system voltage in accordance with IEC 61730 Class A,
but at least for the value of the AC grid voltage
NOTE
Sizing of the PV generator
The device is designed with a reserve of DC short-circuit current withstand capability. This allows oversizing of
the connected PV generator. The absolute limit for the PV generator is the value of the maximum short circuit
current (lsc max) and maximum open circuit voltage (Uoc max).
6.6.3 Connecting the PV generator
DANGER
Risk of fatal injury due to electric shock!
Severe injury or death will result if the live connections are touched. When there is sunlight present on the PV
generator, there is DC voltage on the open ends of the DC cables.
1. Activate the connection power at the switchbox or string combiner with the DC isolator switch.
2. The DC connection is intended exclusively for PV generators. Other sources fall within the scope of im-
proper operation (e.g. batteries).
3. Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
4. Avoid short circuits.
5. Do not connect any strings with a ground fault to the device.

.CAUTION!Risk of fire due to chemical corrosion. Cable lugs must be
suitable for the conductor material and copper busbars being used 5.
7. Press ring cable lug onto DC wires. When crimping, ensure that the ring cable
lug is rotated in accordance with the final installation position.
.CAUTION!Danger to life due to a surge in voltage. If the clearance is
insufficient, shrink tubing (>= 6 kV/mm dielectric strength) must be
used.
8. Guide the shrink tubing over the uninsulated crimping point and a maximum of
20 +0/-2 mm over the cable insulation and shrink-fit using manual shrink-fitting
equipment. However, the shrink tubing must not protrude into the seal of the
cable fitting.
