The cable sections specified in the table are minimum re-
quirements. The correct size must be calculated taking in-
to account the actual length, the type of routing and other
conditions set by the existing regulations.
—
fasten the wires with the wire retainer
—
complete the electric connections and refit all components
by performing the described operations in reverse order
Check that:
—
the characteristics of the power network are suitable for
the device usage values
—
the power supply voltage corresponds to the nominal val-
ue +/- 10%
—
all of the power network disconnect devices must be
equipped with contact openings (3 mm) in order to allow
for complete disconnection, in accordance with the con-
ditions required
Mandatory items:
—
have an omnipolar magneto-thermal circuit breaker and
a padlockable disconnecting switch compliant with the
IEC-EN Standards (contact opening of at least 3 mm), with
adequate breaking power and differential protection, in-
stalled near the equipment
—
connect the device to a properly functioning earthing sys-
tem
—
for any electrical intervention, always refer to the wiring
diagrams contained within this booklet
—
take anti-static precautions in case of weather conditions
where humidity is less than 40%

It is forbidden to earth the device together with pipes,
lightning conductors or the earthing system of a telephone
line. Using an improper earthing system can cause electric
shocks.
0
It is forbidden to connect other devices in parallel to the
unit.
Presence contact
Through this contact it is possible to connect an external de-
vice that inhibits operation of the unit such as: window open-
ing contact, remote on/off, infrared presence sensor, activation
badge etc. In case of power failure, the unit will restart with the
same settings if during the first 7 seconds after power supply is
restored no action is performed.
