INSTRUCTIONS ON FITTING, USING AND
MAINTAINING THE ACTUATOR
Micro One
C
CONNECTING TO THE POWER
SUPPLY
These wiring instructions are directed
exclusively at specialised persons who are
qualified to install electrical systems. Such
persons must at all times comply with current
regulations governing electrical installations.
Danger!
In order to eliminate the danger of
electric shock, disconnect the controls
from the power supply before working
on the actuators or the electrical system. Always
fit a main power switch upstream of the control
line cable with a gap of at least 3 mm between
contacts.
Danger!
Danger of hands being crushed. When
the window is moving, do not insert
your hand between the fixed frame and
the window pane.
Warning!
•
Always arrange for the installation of
change-over switches with mid OFF
position with “live-man” control or equivalent.
•
Connection to the mains is carried out by means
of cables with wires of 1 mm
2
in section and
having the appropriate length to reach the
junction box, which must be placed near the
actuator. The electric cables must be suitably
sized in accordance with the requirements of
each system.
•
It is recommended to install the remote controls,
if any, in such a position that the controlled
automation is visible and at a minimum height of
1.5 m.
•
If the actuator is expected to operate unattended
(automatic or remote operation), it is advisable
to install additional safety devices.
•
For connection to the electric system and
signalling wires, it is necessary that your
carefully follow the instructions given on the side
of the wiring diagrams contained in this manual.
•
Signalling with load is delivered in the following
way:
230V AC Version:
With the chain completely retracted as long as
the closing command stays on, a voltage the
same as that of the power supply is delivered
between conductor no. 1 and conductor no. 4;
with the chain completely out as long as the
opening command stays on, a voltage the same
as that of the power supply is delivered between
conductor no. 1 and conductor no. 5 (refer to
the wiring diagrams). Maximum current with
incandescent lamp: 0.5A.
24V DC Version:
With the chain completely retracted as long as
the closing command stays on, a voltage the
same as that of the power supply is delivered
between conductor no. 1 and conductor no. 2;
with the chain completely out as long as the
opening command stays on, a voltage the same
as that of the power supply is delivered between
conductor no. 1 and conductor no. 3 (refer to
the wiring diagrams). Maximum current with
incandescent lamp: 0.5A.
Warning!
If the actuator to be installed is in the
24V DC version, it must be connected
to the mains with a double insulation
power supply with very low safety voltage that is
properly sized for its use.
