Wiring of the various components of the system
The first electrical operations to be performed on the machine, even before powering it, are those of wiring
the various devices that compose it:
x
supervision network (where present);
x
other optional components.
ATTENTION: The sizing and laying of the cables that connect the machine to all its external
components must be carried out in compliance with the laws in force in the country in which it is
installed.
ATTENTION: Regarding the laying of cables, where possible, it is recommended to avoid a common
path between the cables used to transport energy for powering the partly-completed machine, or
in general for powering motors (fans, solenoid valves, etc.). and those dedicated to the transmission
of signals (such as network cables, 0/10V, etc.). Failure to comply with this provision could
jeopardise correct functionality of the system due to serious capacitive couplings that disturb the
communication of very low power.
Supervision network
ATTENTION: Where possible, it is recommended to keep the partly-completed machine supervision
network separate from that of the supermarket control devices (desks, cells, cabinets, etc.). This is to
avoid accidental overwriting of parameters between devices with the same network addresses.
For the wiring of the RS485 serial line on which the supervision network will sit, the following are recommended:
x
use BELDEN 8762 AWG20 type cable;
x
minimise the length of the serial line (RS485 max 1000m).
Do not create bifurcations of the line or star connections, as shown:
