from the bottom of a well so that sand is not lifted.
A safety rope or chain of non-perishable material
should always be used to secure a suspended pump.
EN
When a plastic or flexible delivery pipe is used,
the safety rope or chain should be utilized for
lowering, securing and raising the pump.
Never use the electric power cable to
suspend the pump.
Attach the power supply cable to the delivery pipe
and to the safety rope with cable clamps at inter-
vals of about 3 m. The power cable should not be
taut: allow for a certain degree of slackness
between the clamps to avoid the risk of strain
caused by expansion of the pipe during operation.

6.5 Electrical connection

OFF
Electrical connection must be carried out
only by
accordance with local regulations.
Follow all safety standards.
he unit must be always earthed, also with a
non-metallic delivery pipework.
ATTENTION: in the case of water
containing chloride (or salt water), the
earthing (grounding) conductor is useful
also to reduce the risk of galvanic corrosion
due to electrolytic action, especially with
non-metallic delivery pipe and safety rope.
Make sure the frequency and mains voltage cor-
respond with the name plate data.
For use in swimming pools (not when people are
in the pool), garden ponds and similar places, a
residual current device with IΔN not exceeding
30 mA must be installed in the supply circuit.
Install a device for disconnection from the
mains (switch) with a contact separation of at
least 3 mm on all poles. When the water level is
not under direct visible control, install a float swit-
ch or electrodes to protect the pump against dry
running and to set the water levels to stop and
automatically start the pump.
The pumps are supplied with power cable type
H07-RN8-F type with section of cable not less
than 11 TAB IEC 60335-1.
When extension cables are used, make sure the
cable wires are of adequate size to avoid voltage
drops. For connection of cables in a well, use
thermo-shrinking sheathes or other methods for
submersed cables.
ATTENTION:
When the pump is fed by a frequency converter,
the minimum frequency should not fall below 25
Hz and in any case the total head of the pump
should never be lower than 2 m.

6.5.1 Single-phase pumps MXSM
OFF
Supplied with incorporated capacitor and thermal
protector, with plug.
Connect the plug to a socket with an earth lead.
The motor will stop if overheating is detected.
When the windings cool down (after 2 to 4 min-
utes), the thermal protector enables re-starting.

6.5.2 Three-phase pumps MXS
OFF
Install in the control box an overload-protective
device in accordance curve type D with the name-
plate current.

7 STARTUP AND OPERATION

7.1 Preliminary checks before start-
up of the pump
Do not start-up the device in case of damaged
parts.
7.2 First starting
OFF
With a three-phase power supply make
i
sure the direction of rotation is
correct.
