ELECTRICAL WIRING

WARNING: before carrying out any work, make sure
the electrical power is unplugged.
In particular, the following checks are required for electri-
cal connections:
- Measurement of the electrical system insulation strength.
- Continuity test of the protection wires.
The electrical circuits are connected to the mains voltage of
230V; all the connections and components must therefore
be correspondingly insulated for this tension.
CHARACTERISTICS OF THE CONNECTION CABLES
Use cables of the H05V-K or N07V-K type with 300/500 V
insulation.
Use power cables with a minimum cross-section of 1.5 mm
All the cables must be in pipes or raceways until they are
inside the fan coil.
The cables leaving the pipe or raceway must be positioned
in such a way that there are not traction or twisting stresses
and they are anyway protected from outside agents.
In the Omnia UL-P PC models, after removing the electrical
cover box, you will see a bracket with two cable holes to
feed the cables through.
Follow the wiring diagram with the equipment and shown
in this document when making the connections.
To protect the unit against short circuits, fit an omnipolar
thermal-magnetic trip 2A 250V (IG) to the power line with
a minimum contact opening distance of 3 mm.
Each control panel can control a single fan coil.

COIL ROTATION

If for plumbing reasons it is necessary to rotate the coils,
after removing the mobile section, proceeds as follows:
– remove the electrical connections from the terminal strip;
– remove the screws fixing the basin and remove it;
– remove the screws fixing the coil and remove it;
– remove the partially cut parts from the right-hand side;
– rotate the coil and fix it with the previously removed
screws;
– refit the basin fixing it in position with the screws, insert
the plastic caps supplied, in the holes left free by the
plumbing connections;
all the basins can be used for drainage on both sides.
N.B.: Before connecting the condensate drainage pipe,

.
push in the diaphragm off the basin (if present) on the
plumbing attachment side, seal the drainage not used
with the cap provided.
– slide out the electrical connection from the right-hand
sided, remove the partially cut section and move the
cable fairlead from the right-hand side to the left;
– move the motor cable on the left hand side and pass it
through the cable fairlead ;
– move the terminal block and the U-bolt of the ground on
the left-hand side;
– restore the motor wire electrical connections;
