ELECTRICAL POWER SUPPLY
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 2 2A type T fuses, (GS) or 1 4A mag-
netothermic breaker.
The switches must also provide disconnect capability,
with min contact opening 3 mm.
How to connect the power supply
To connect the three-pole power supply cable (Figure
4.2
p. 19):
1. Access the Electrical Board of the appliance according to the
Procedure 4.2
p. 18.
2. Connect the three wires to terminal board (MC) in the elec-
trical 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).

SET-UP AND CONTROL
Control systems, options (1) (2) (3)
Three separate adjustment systems are provided, each with
specific features, components and diagrams (see 4.4
p. 20,
4.5
p. 21):
▶
System (1), with DDC control (with CAN-BUS connection).
▶
System (2), with CCP/CCI control (with CAN-BUS connec-
tion).
▶
System (3), with an external request.
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
CCP/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, CCI, ...), 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).
CAN-BUS signal cable
The DDC controller is connected to the appliance through the
CAN-BUS signal cable, shielded, compliant to Table 4.1
p. 20
(admissible types and maximum distances).
For lengths ≤200 m and max 4 nodes (e.g. 1 DDC + 3 GAHP), a
simple 3x0.75 mm shielded cable may even be used.
