The cross sections shown in this table refer to a maximum length of 10 metres
** The maximum length of the cables for connection to the optional Battery Box is 3 metres
Note: the maximum cross section of the cables that can be inserted in the terminal board is:

ONNECTIONS
The very first connection to be carried out is that of the protection conductor (earth cable), which must
be connected to the terminal marked PE. The CPS must not operate without being connected to an
earthing system
THE INPUT AND THE BYPASS NEUTRALS MUST ALWAYS BE CONNECTED.
THE INPUT AND BYPASS LINES MUST REFER TO THE SAME NEUTRAL POTENTIAL.
Connect the input and output cables to the terminal board as shown in the figure below:
Note 1: The protection conductor (earth cable) connection must be carried out through eyelet terminal stud M6
Note 2: Connections to the BATTERY module are required only when the optional Battery Box is present
