WARNINGS!
– The PVC power supply cable supplied serves exclusively for
automation operation and programming tests.
– The final connection of the automation to the electrical
mains and replacement of the cable supplied, must be per-
formed by a qualified electrician, in compliance with local
standards and the instructions in the section "Tasks reserved
for qualified technicians".
– The replacement cable must be suitable for outdoors, such
as type H07RN-F. The cable must also be protected against
impact by means of an insulated protection duct.
To perform the automation operation and programming tests, insert the
power plug of the control unit (supplied) in a mains socket (fig. 40). If the
socket is far from the automation, use a suitable extension lead.

After powering up the control unit (fig. 50), the red Led and green Led
(fig. 41) emit a series of flashes.
At the end of this phase, the red led starts flashing at regular intervals.
This confirms correct operation of the control unit.
