ELECTRICAL WIRING
The indoor and CXS H units must be connected electrically
to each other as shown in the wiring diagrams.
To protect the unit against short circuits fit an omnipolar ther-
momagnetic switch 250V (IM1) (with power 1~ 230V 50Hz
) on the power line, with a minimum contact opening distance
of 3mm (TAB. F).
The connection terminals of the CXS-H unit are connected
in the electrical box that can accessed by removing the pla-
stic plug at the side.
For connections between the units, the values of the cable
cross sections and the IM switch, see the “Wiring Diagram”
section.
During installation it is possible to select two head levels
(standard or maximum head) connecting the power supply
of the fan motor to clamps 3 or 4.
