6.6. ELECTRICAL CONNECTION
The CAD-COMPACT ECOWATT range are supplied without a complete operating control integrated in the
unit. The electrical components included in the unit are supplied wired in an electrical cabinet located
in one side of the unit. To access the electrical terminal block and conveniently make the electrical con-
nection of the accessories it is advisable to remove the connection board, follow the following sequence:
