Control bus cables routing
Place and fix the cables JA and JB with the appropriate clamps inside the UPS cabinets.
Pay attention to the fact, that routing of cables shall allow the removal of the protection covers.
NOTE !
Pay attention when cabling and routing the bus cables JA and JB inside the UPS
cabinet.
In case the unit should be removed from the system, the control bus cables Group A
and Group B must be removed from the cabinet without disconnecting them from
the metal plates where are located the sockets JA and JB. Please contact your
Service Centre.
For reliability reasons the cables JA and JB connecting the units should be run in separated
protected conduits, as well as separated from the power cables.
It is important that the cable JA is as long as cable JB.

Since the position of PC Board “P34 – Parallel Bus Interface” inside the UPS changes
between the various UPS output powers, it’s recommended to consult the
appropriate Operating Manual for cable connections.
