Italtecnica CRONO SPY Manuel D'instructions page 22

LINE CONNECTION
The device power supply is single phase at 230 Volt 50/60Hz. The electrical system to which the device
is connected must comply with current standards and must therefore be fitted with:
- automatic thermal magnetic circuit breaker with high breaking power and trip current in proportion to
the power of the pump installed
- earthing connection with total resistance in conformity with local standards and in any event no more
than 100Ω.
If the device is used in swimming pools, fountains, or garden ponds, a residual current circuit breaker
type "A" must be installed, with I∆n=30mA
If the device is not equipped with a power cable and plug, install another device that ensures single pole
disconnection from the mains with a contact opening gap of at least 3 mm.
If the terminals supplied are not used, the faston terminals must be crimped by specialist personnel using
special pliers.
The recommended cable section is 1.5 mm
The type of electric cable must correspond to the conditions of use (use in domestic rooms, dry or wet, for
installation indoors or outdoors).
ELECTRIC PUMP CONNECTION
The recommended cable section is 1.5mm
The type of electric cable must correspond to the conditions of use (use in domestic rooms, dry or wet, for
installation indoors or outdoors).
Also observe the installation limits as declared by the manufacturer of the electric pump connected to
Crono Spy.
CAUTION:
- all electrical connections must be made by specialised personnel
- incorrect connections of the electric motor can cause damage to the device or the pump motor
itself.
- failure to observe the instructions in this section can cause serious damage and/or physical injury
and releases the manufacturer from all liability.
- in the event of damage to the power cable or the cable between Crono Spy and the electric pump,
it must be replaced exclusively by the device manufacturer or assigned and suitably qualified
personnel, to prevent risks to objects and persons.

, compatible with electric pumps up to 12A.
Crono Spy can be installed on single phase pumps with
230Vac power supply, already fitted with a capacitor.
Therefore at the time of electrical connections, ensure that the
terminals in the electrical compartment of the motor are
connected according to the instructions of the electric pump
manufacturer. The figure alongside shows a typical example of
connection:
If the terminals supplied are not used, the faston terminals
must be crimped by specialist personnel using special pliers.
