ELECTRICAL POWER SUPPLY
4.3.1 Power supply line
Provide (by the installer) a protected single phase line (230 V 1-N
50 Hz) with:
▶
1 three-pole cable type FG7(O)R 3Gx1,5
▶
1 two-pole switch with two 5 A type T fuses, (GS) or one 10 A
magnetothermic breaker

The switches must also provide disconnector capability,
with min contact opening 4 mm.
How to connect the power supply
To connect the three-pole power supply cable (Figure
4.2 p. 25):
1. Access the electrical board of the appliance according to
the Procedure 4.2 p. 24.
2. Connect the three lead-in wires to the terminal block
(TER) in the electrical panel on the machine.
3. Provide the earth lead-in wire longer than live ones (last
to be torn in the event of accidental pulling).
4.4 ADJUSTMENT AND CONTROL
4.4.1 Control systems
Three separate control systems are provided, each with spe-
cific features, components and diagrams (Figures 4.4
p. 26,
4.7 p. 28):
1. DDC control (with CAN bus connection).
2. CCP/CCI control (with CAN bus connection).
3. External request.
4.4.2 CAN bus communication network
The CAN bus communication network, implemented with the
cable of the same name, makes it possible to connect and re-
motely control one or more Robur appliances with the DDC or
CCI control devices.
It entails a certain number of serial nodes, distinguished in:
▶
intermediate nodes, in variable number
▶
terminal nodes, always and only two (beginning and end)
Each component of the Robur system, appliance (GAHP, GA, AY,
...) or control device (DDC, RB100, RB200, ...), corresponds to a
node, connected to two more elements (if it is an intermedi-
ate node) or to just one other element (if it is a terminal node)
through two/one CAN bus cable section/s, forming an open lin-
ear communication network (never star- or loop-shaped).
