Electrical Connection - Italtecnica Sirio Instrucciones De Uso

 ELECTRICAL CONNECTION:
WARNING:
- all wiring up must be carried out by specially trained personnel
- an incorrect motor pump connection could result in damage to the device or the pump motor.
- failure to comply with what is stated in this paragraph may cause serious damage to things and/or serious injuries to people, and
the manufacturer declines all responsibility.
- if the power supply cable or the cable between the Sirio 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.

residual current operated circuit breaker (with IΔn=30mA) must always be fitted.
The system comprising the Sirio and a motor pump is considered a "fixed system"; it is therefore advisable to make arrangements to 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.

use (domestic, dry or wet, indoor or outdoor installation).
IT
LINE
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
100Ω
If the device is used in swimming pools, fountains or garden ponds, an automatic type "A"

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
green terminal marked "LINE"; then proceed with connection of the earth wire to
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 mm2, which is compatible with motor
pumps up to 1.1 kW. For powers over 1.1 kW and up to 2.2 kW 2.5 mm
