- if the power supply cable or the cable between the inverter and the pump is damaged, only the manufacturer of the device, its
appointee or equally qualified personnel can replace it; this is to prevent risks to things and people.
Fit the electric wires into the relative wire clamps, making sure the correct assembly order is maintained for all the components. Secure the
threaded nuts tightly enough to prevent the wires being pulled or turned from the outside.
The wire clamp for the auxiliary contact is a blind fastener: if you wish to insert a remote control wire, it is best to remove the said nut from
the unit, then break open the plastic nut with a screwdriver.
The hole diameter for the cable gland should be 7 mm.
Use the provided grommet with the cable gland. It is suitable for cables from 3.5 mm to 6.5 mm.
If the device is used in one of the following situations:
- temperature of the fluid used higher than 30°C
- ambient temperature higher than 35°C
cables with a thermal resistance of at least 100°C must be used for the power supply and motor cable.
LINE CONNECTION
The device has a single-phase 230 Volt 50/60Hz power line.
The electrical system to which the equipment is connected must comply with the safety
regulations in force and must therefore be equipped with:
- an automatic magnetothermal switch with high breaking capacity and with a trigger current
proportional to the capacity of the pump installed (see chart below)
- earthing with total resistance in conformity with local standards and in any case never over
reaker (with
mA) must always be fitted.
The system comprising the inverter
prevent the device being disconnected from the power line it was originally connected to and mistakenly reconnected to another source of
power not equipped with the electrical protection required.
If the device is not fitted with a power lead and plug, to disconnect it from the mains install an omnipolar cut-off device with a gap of at least
3 mm between the contacts.
Before making the electrical connection, the cables must be prepared with the
supplied crimp terminals. Connect the two device power wires to the 2-pole
gree
one end of the double earthing terminal using the special eyelet terminals
supplied. The faston terminals must be crimped by specially trained personnel,
using proper crimping pliers.
The recommended wire section is 1.5 mm
2 .
If the power lead is longer than 5-10 metres, a lead with a 2.5mm 2 section should be used to reduce drops in the power supplied by the lead
and to reduce the chance of the under-voltage protection being triggered. The type of wire must be selected according to the conditions of
use (domestic, dry or wet, indoor or outdoor installation).
ELECTRIC PUMP CONNECTION
Before carrying out the electrical connection, is necessary to properly prepare the cables with special crimp terminals. Connect the two
power supply wires to the green bi-polar terminal on the pump motor, marked with the word "MOTOR"; then connect the earthing cable to
one end of the double earth terminal, using special eyelet terminals. The crimping of the terminals must be carried out by specialised
personnel, using proper pliers.
The device is fitted with an output short circuit protection.
For the sction of the cable to employ please refer to the pump manual.
Where an excessive cable length (over 80 metres) is used, it is recommended to insert a dV/dT filter to limit peak current voltage and
safeguard the durability of the motor, particularly the windings.
