IMPORTANT WARNINGS:
• the earth connection must be made to the same point in the earth line (same earth pole, for all the pCO boards)
• with these configurations (Figs. 5.e, 5.f and 5.g) Class 2 safety transformers must be installed.

5.7 Remote installation of a terminal in a pLAN network
When the pCO boards are connected in a pLAN network, the terminal can be remotely-installed at a distance of up to 50 metres, if using a telephone cable, while it
can be located at a distance of up to 500 metres if using a shielded cable, TCONN6J000 and a separate power
supply.
Note
NoteNote
Note: to reach the maximum length, use a bus layout with branches that do not exceed 5 m.
The following figures show the connection diagrams for the various configurations.
If using the terminal in a residential environment, the cable must be always shielded
