Italtecnica Sirio Entry 230 Instrucciones Para El Uso página 28

The terminals must be crimped by specialist personnel, using special pliers for the purpose.
The recommended wire section is 1.5mm2, which is compatible with motor pumps up to 1.1 kW.
For powers over 1.1 kW and up to 1.5 kW a 2.5mm
If the power lead is longer than 5-10 metres, a lead with a 2.5mm2 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).
All installation restrictions stated by the manufacturer of the motor pump to which the Sirio Entry
is connected must also be observed.
AUXILIARY CONTACT CONNECTION
WARNING: The remote connector is insulated from the network power by a "main" type
insulation (basic insulation according to EN 60730-1). Any circuit which will be connected to
this terminal, will acquire the same insulation grade from the network power. For this
reason the connection must be carried out using a cable type that can guarantee the
additional insulation.
SETTING OF "AUXILIARY CONTACT" PARAMETER = "1" – Exchange function in the
pressurisation units.
When the "AUXILIARY CONTACT" parameter is set
on "1" the Sirio Entry is set to work independently
(single system) or to dialogue with another partner
device as part of a twin pump pressurisation unit,
depending on whether the connection cable is used. If
the device is set to work independently no connection
is required. On the other hand, if the Sirio Entry is connected to another unit to create a
pressurisation group, follow the wiring diagram shown here; for further information on the
operation as part of twin pump pressurisation units see the "PRESSURISATION UNITS" section
in the appendix.

wire section is recommended.
Sirio Entry is fitted with a special connector for an
auxiliary contact so that additional functions can be
exploited by interfacing the device with external
equipment. The function of the auxiliary contact
depends on the setting of the "Auxiliary Contact"
parameter described
programming. The three operational modes,
relevant functions and connection methods are
described below.
