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.
You must adjust the minimum frequency to
a value that ensures water is discharged
from the outlet of the pump
To adjust the min Frequency click the
home button on the control panel and
select min Frequency
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.
Please ensure that the mounting wall can
support the weight of the inverter. Find
weight in 3.2 Technical data.

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.
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.
