Place the cables and connect them as indicated in the diagram Fig. 3.9.5-4 following these
procedures:
• Fix the control bus cables with the appropriate tie-wrap “E”.
• Place the cables between the parallel units in separated protected conduit to avoid they could
be accidentally interrupted.
• Put in place the front screen “B” (Fig. 3.9.4-1) paying attention to not damaging the control bus
cables.
It is important to place the units in sequence of their assigned number.
A unit number from P1 to P4, is defined by the setting of parameters and displayed on the control
panel.
This number is also marked inside and outside the packaging.
The standard length of the control bus cable between two parallel unit is 26 ft / 8 m (higher length on
request = up to 50 ft / 15 m).
Maximal overall length of bus connection, between the first and the last unit, should not be longer than
345 ft (45 m).
