ELECTRICAL CONNECTION:

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.
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.
MOTOR PUMP CONNECTION
Sirio Entry can be fitted on single-phase 230Vac electric pumps, already provided with capacitor. When
wiring up the device it is necessary to check the terminals inside the pump to ensure they are connected as
prescribed by the manufacturer of the pump. The figure below shows a typical example of connection:
T o m a k e t h e e l e c t r i c a l c o n n e c t i o n , e x t r a c t t h e g r e e n b i p o l a r t e r m i n a l m a r k e d " MO T O R " a n d c o n n e c t t h e
two pump motor power wires; then fit the terminal back onto its seat and proceed by attaching the earth
wire to one end of the double earth faston. The faston terminals must be crimped by specially trained
personnel, using proper crimping pliers.
This device can run with pumps with a max. rated frequency of 50Hz (60Hz optional) and a capacity of
up to 1500 Watt.
The equipment is fitted with an output short circuit protection.
The wires have a 1.5 mm
recommended that 2.5 mm
2
section and lengths of up to 30 m; for lengths from 30 m to 50 m it is
2
section wire be used.
