1.06 GENERAL SAFETY PRECAUTIONS
When using electrical equipement, it is ne-
cessary to take the appropriate safety pre-
JH\[PVUZ [V YLK\JL [OL YPZR VM ÄYL LSLJ[YPJHS
shock, and injury to person. Therefore, before
using the equipement, carefully read and me-
morize the following safety instructions. After
reading, keep this brochure with care. The ma-
nufacturer shall not be heald liable for any non-
observance of the safety and accident-preven-
tion instructions described in this brochure.
- Keep the work area clean and tidy. Untidy areas
and environments make accidents more likely.
- Before starting work, become familar with the
control devices and their functions.
- Do not subject the equipment to work it could
not reasonably support.
- Operate only with good lighting, in a safe po-
sition free from hindrances.
- When handling the motor use suitable lifting.
- Equipment in conformity with the safety regu-
lations, and wear safety shoes and gloves.
- Never handle the equipement by pulling in its
power cable.
- Use only cables of allowed lenght, marked
and with suitable cross-sections.
- Protect the cable from high temperature, lubri-
ÄJHU[ZHUKZOHYWJVYULYZ
- During the installation operations, pay atten-
tion to hanging loads and follow the correspon-
ding safety instructions.
- Make the control panel and the electrical sy-
stem in accordance with current regulations.
- It is essential to use skilled personnnel since
motor are machines that due to their type of in-
stallations and starting to require precise tech-
nical knowledge.
1.07 OPERATING CONDITIONS
-Liquids in wich the motor can operate
This motor can be used in cold water. Do not
use this motor with corrosive or explosive li-
quids, or particularly dirty or hard water (impuri-
ties may deposit on the outer casing).
-Water temperature
Minimum water temperature is 0°C
Maximum water temperature is +35°C as long
HZ[OL ÅV^YH[LVM [OL^H[LY HYV\UK[OLTV[VY
does not fall below 0.16m/s

-Cooling the motor
To ensure the motor is correctly cooled, make
sure the plowrate of the water around the outer
casing is at least 0.16m/s when positioning the
motor in wells or tanks.
-Installation position
All the motors in the range can be installed
vertically.
Motors up to 2.2 kW power can be installed
horizontally.
-Depth of immersion
The maximum depth of immersion for all motors
is 150m.
-Power supply requirements
Make sure the supply voltage and frequency
match yhose indicated on the rating plate of the
motor.
The motors can generally work at the following
supply voltage tolerances.
f UN
Hz ~ V ± %
50 1 220V ± 10%
50 3 220V ± 10%
50 3 380V ± 10%
-Number of starts per hour
To get the best operation and longest service
life out of your motor and pump, the maximum
number of starting times is not more than 30
times.
-Compatible pumps
Make sure the motor is compatible with the
pump.
Incompatible combinations may cause pro-
blems.
In particular, before coupling the motor to the
pump check that:
-the power of the pump to couple to the motor
is less than or equal to that of the motor.
- the supply voltage and frequency match those
PUKPJH[LKVU[OLPKLU[PÄJH[PVUWSH[LVM[OLTV-
tor.
-the motor and pump shafts turn freely.
-Motor powered by a frequency converter
Only specially ordered motors can be powered
with a frequency converter.
If the motor is combined with a frequency con-
verter, downgrade power by 10% and make
sure never exceed the rated input frequency of
the motor.
To ensure the motor is properly cooled, the mini-

cated in the previous points.
2.00 INSTALLATION
Installation must be done by competent and
authorized operators.
During installation,apply all the safety pro-
visions issued by the competent bodies in
the country of use and dictated by common
sense.
Before installing the motor, read this instruc-
tions manual and the one supplied the pump
or electric pump to wich the motor will be cou-
pled. Keep both manuals with care.
Use suitable equipment and protective devices.
-Selecting the electrical panel
Motors must be suitably protected against
overloads and short circuits.
The following starting systems can be used:
direct, impedance, autotransformer, soft-start.
Make sure the panel power ratings match those
of the pump. Incompatible combinations may
cause faults and fail to fully protect the motor.
Before installing, carefully read the instructions
supplied with the electrical panel.

- Pump connections
Before connecting the motor to the pump, read
this instructions manual and the one supplied
with the pump or electric pump to wich the mo-
tor will be coupled.
Keep both manuals with care.
-Installing the motor in a well or tank
Follow the instructions in the pump or electric
pump brochure.
When installing the electric pump vertically,
make sure the motor does not rest on the bot-
tom of the well ot tank.
When installing the electric pump horizontally,
make sure the motore does not rest on the bot-
tom of the tank.
2.01 START-UP
Follow the instructions in the pump or electric
pump manual
