Nibe ACS 45, Installer Manual

Page: 24 / 92

CONNECTING COMMUNICATION
ACS 45 contains an accessory board (AA5) that connects
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.
