1.3 Choosing the installation location
Installation environment
1. Ensure that the inverter is installed out of the reach of children.
2. To ensure an optimal operation and a long service life, the temperature of the installation environment of the inverter
should be ≤40 °C.
3. To avoid direct sunlight, rain, snow and moisture on the inverter, we recommend to install the inverter at locations with
a protective roof. Do not completely cover the top of the inverter.
4. The installation conditions must be able to accommodate the weight and size of the inverter. The inverter is suitable for
mounting on a solid wall that is vertical or sloping backwards (max. 15°). It is not recommended to install the inverter on
a wall made of plasterboard or similar materials. The inverter may emit audible noises during operation.

Fig. 2: Permissible installation location
5. To ensure adequate heat dissipation, the following clearances are recommended between the inverter and other
objects:

1.4 Mounting the wall bracket
CAUTION
Hazard when using unsuitable fixing materials!
If unsuitable fixing materials are used, the device could fall and persons under the device may be seriously
injured.
› Use only fixing materials that are suitable for the mounting base. The fastening materials supplied are
only suitable for masonry and concrete.
› Only install the device in an upright position.
NOTE
Power reduction due to heat accumulation!
If the recommended minimum clearances are not observed, the device may go into power regulation
mode due to insufficient ventilation and the resulting heat build-up.
› Observe minimum clearances and provide for sufficient heat dissipation.
› All objects on the device housing must be removed during operation.
› Ensure that no foreign bodies prevent heat dissipation following device installation.

Coming into contact with live connections can cause serious injury or death. When there is sunlight
present on the PV generator, there is DC voltage on the open ends of the DC cables.
› Make sure PV modules have good insulation against ground.
› On the coldest day based on statistical records, the Max. open-circuit voltage of the PV modules
must not exceed the Max. input voltage of the inverter.
› Check the polarity of DC cables.
› Ensure there is no DC voltage present.
› Do not disconnect DC connectors under load.

Damage to the inverter due to electrostatic discharge
Internal components of the inverter can be irreparably damaged by electrostatic discharge or connection
of unsuitable USB devices.
› Ground yourself before touching any component.
› The COM3 connection is only suitable for the Wi-Fi stick included in the scope of delivery
or the 4G stick optionally available from KACO new energy.
The device has been installed on the mount.
1 Remove the cap on the COM3 connector (Pos. 1).
2 Insert the WiFi module (Pos. 2) into the existing connection and screw it into the
connection using the nut on the WiFi module.

NOTE
A network cable of category 5E or higher is required for connection to the RJ45 socket.
For outdoor use, UV resistance and a maximum installation length (over all inverters) of 1000m are
permitted.
Damage to the inverter due to electrostatic discharge
Internal components of the inverter can be irreparably damaged by incorrect wiring between the power
and signal cables. All warranty claims are thereby rendered invalid.
› Ensure that the cable is correctly assigned.
The device has been installed on the mount.
1 Unscrew the cover cap of the communication connection (COM1 or COM2) (see illustration below, observe the sequence
and directions of the arrows).
2 Feed the network cable through the thread sleeve (incl. forcing nut).
3 Configure the communication line as shown in Figure 19 (according to DIN 46228-4, provided by the customer).
4 Plug the network cable into COM1 or COM2 (see Fig. 20. Note the sequence and directions of the arrows)
