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. 6 below. 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.

6.2 Fault codes reset

When a fault appears and the RSI stops, examine
the cause of fault, perform the actions advised in
section 6.1 and reset the fault as instructed below.

1. With a long (1 s) press on the Reset button on
the keypad or

2. By entering the Diagnostics Menu (M4), entering
Reset faults (M4.2) and selecting Reset faults
parameter.

3. For keypad with LCD display only: By selecting
value Yes for the parameter and clicking OK.

6.3 Fault history

The inverter will record the forty most recent fault
codes. Searching this information will help
investigate the fault cause. Fault information is
stored together with additional informationsin the
fault history menu.

7. Service and maintenance

7.1 Routine inspection

To ensure the inverter runs stably, carry out an
annual inspection.

7.1.1 Inspection and maintenance requirements

1. If it is necessary to conduct an insulation test on
the inverter, all input and output terminals must
have a proper short-circuit. Insulation tests must
not be performed on a single terminal. Use a 500
V mega ohm meter to conduct the test.

2. When conducting an insulation test on the motor,
dismantle the connection between motor and
inverter.

Caution

Check the fault cause thoroughly and
remedy it before resetting. If it cannot be
reset or persists after resetting, check the
cause again as continuous resetting will
damage the inverter.

Caution

In case of overload and overheat
protection, delay the resetting for 5
minutes.

Warning
Maintenance and inspection must be

performed by a qualified electrician.
Do not dismantle the inverter when it is

running. The inverter must be powered off
at least 5 minutes before conducting
maintenance and inspection.

It is absolutely forbidden for unauthorised
persons to repair the inverter as this can
cause personal injury or equipment
damage.

Note

Any service performed on the inverter by
unqualified staff will void the warranty.

Warning
The inspection must be performed by

trained and qualified technical staff.
Disconnect the power supply to the
inverter before starting inspection

Caution

Do not use the mega ohm meter to test the
control circuit.

7.2 Inspection and replacement of wear
parts

7.2.1 Cooling fan

Inverters are equipped with cooling fans. The
cooling fan's service life is about 15000 hours. If the
fan generates abnormal noise or produces
vibrations, replace it immediately. The cooling fan
will start automatically when the internal temperature
of inverter is higher than 55 °C and stop when the
internal temperature of inverter is lower than 45 °C.

7.3 Storage and warranty

7.3.1 Storage

If the product is stored for a long time after
purchasing, comply with the following requirements:

1. Avoid placing the inverter in high-temperature or

humid areas or areas with vibration and metal
dust. Ensure ventilation.

2. The performance of the capacitor inside the

inverter can be reduced if the equipment is not
used for a long period of time. It is thus
necessary to start up the equipment every two
years to restore the performance of the capacitor
and inspect the inverter function at the same
time. The voltage must be increased gradually
through a DC power supply with power-on time
being not less than 5 hours.

7.3.2 Warranty

The following situations are not covered by the
warranty:

• Faults caused by failure to comply with this

manual or standard specifications.

• Faults caused by self-repairing and modification

without permission.

• Faults caused by poor storage and maintenance.

• Faults caused by abnormal use of the inverter.

• Damage caused by fire, salt corrosion, gas

corrosion, earthquake, storm, flooding, lightning,
abnormal voltage or other force majeure
situations.

8. Disposal

This product or parts of it must be disposed of in an
environmentally sound way:

1. Use the public or private waste collection service.

2. If this is not possible, contact the nearest

Grundfos company or service workshop.

Subject to alterations.
