Control bus cables routing
Place and fix the cables JA-1/2/3/4/5 and JB-1/2/3/4/5 inside the UPS cabinets in the position
illustrated in the drawing Fig. 3.10.3-3.
NOTE !
Pay attention when cabling and routing the bus cables JA and JB inside the UPS
cabinet.
In case one unit should be removed from the parallel system, the bus cables JA
and JB must be removed from the cabinet without disconnecting them from the
metal plate where the sockets JA and JB are located.
For reliability reasons the cables JA-1/2/3/4/5 and JB-1/2/3/4/5 connecting the units should be run
in separated protected conduits (as indicated in Fig. 3.10.3-3) separated from the power cables.
It is important that the cable JA must be the same length as cable JB.
WARNING !
Connection and commissioning of an additional UPS to an existing parallel system,
must be performed by a GE SERVICE ENGINEER from of your
Service Center.
