NOTE
All electrical connections must be carried out
by an authorised electrician.
Electrical installation and wiring must be carried
out in accordance with the stipulations in force.
The main product must be disconnected from
the power supply when installing HPAC S40.
• To prevent interference, sensor cables to external
connections must not be laid close to high voltage
cables.
• The minimum area of communication and sensor
cables to external connections must be 0.5 mm² up
to 50 m, for example EKKX, LiYY or equivalent.
• Mark the relevant electrical cabinet with a warning
about external voltage, in those cases where a com-
ponent in the cabinet has a separate supply.
• HPAC S40 restarts after a power failure.
The electrical circuit diagrams are at the end of this In-
staller Manual.

CONNECTING COMMUNICATION
HPAC S40 contains an accessory board (AA5) that con-
nects directly to the main product's PCB (terminal block
AA2-X30).
If more accessories are to be connected, or are already
installed, the boards are connected in series.
Because there can be different connections for accessor-
ies with accessory board (AA5), you should always read
the instructions in the manual for the accessory that is
to be installed.
