4. Installation
4.1 Installation example
Fig. 4 Installation example showing the required clearance when mounting the product
Warning
Installation must be carried out by qualified
staff.
Caution
You must adjust the minimum frequency to
a value that ensures water is discharged
from the outlet of the pump
Note
To adjust the min Frequency click the
home button on the control panel and
select min Frequency
Caution
To ensure a good convective cooling
effect, install the inverter vertically with at
least 10 cm free space at the top and
bottom.
To be installed indoors. Do not install the
equipment in direct sunlight.
Caution
Please ensure that the mounting wall can
support the weight of the inverter. Find
weight in 3.2 Technical data.

4.2 Electrical connection
Fig. 5 Position of terminals
Warning
To avoid the risk of electric shock or fire,
make sure that the power supply has been
cut off before connecting the equipment.
To avoid live voltage on the cabinet, make
sure the earth terminal is reliably
grounded.
Caution
To avoid arcing and fire, tighten all
terminals with the specified torque.
For distances (pump to inverter) exceeding
30 m, we recommend a reactor with
matching current ratings.

5. Operation
5.1 Control panel
The Renewable Solar Inverter control panel is shown
in fig. 6below. The control panel has four LEDs, a
digital display and nine operating keys.
Fig. 6 Control panel layout
Warning
Check all electrical connections before
powering up the system.
Warning
The heat sink becomes hot during running
and stays hot for a long time. Touching it
while it is hot will cause burns.
Caution
In case of altitudes over 1000 m, the
output current should be reduced by 10 %
for every 1500 m increase in altitude.
Note
Adjust control parameters according to the
steps indicated in this manual before the
first start.
