BUS cable for communication between condensing unit and cells
Twisted and shielded cable 3x0.5mm
2
maximum length
100m.
Connect the cable to the terminals of the electronic
cards as shown in the block diagram and in the electri-
cal diagrams. Comply with the codes on the terminal
block. The sequence of connection of the units does
not make any difference. Start with the BUS of the
Master card (condensing unit).
Connect the shield of the BUS cable to earth only in the
electrical panel of the condensing unit.
ATTENTION! The shield must be connected to earth only in the condensing unit.
If several cells are to be connected with the bus, the shield of the incoming cable must be spliced with the shield of
the outgoing cable. In the cell where the bus ends, the shield must be isolated.
The manufacturer declines any responsibility
or guarantee obligations if damage occurs to the
unit, persons or things due to installation that is
incorrect and/or does not respect the laws in force.
