Control bus cables routing
Place and fix the cables
J1A – J2A
(1/2/3/4/5) and
J1B – J2B
(1/2/3/4/5) inside the UPS cabinets in the position
illustrated in the drawing Fig. 4.9.3-3.
Note!
Pay attention when cabling and routing the bus cables JA and JB inside the UPS cabinet.
In case one unit must be removed from the RPA Parallel System, the communication bus cables
must be taken out the UPS cabinet WITHOUT DISCONNECTING THEM from the two boards “P13/P14
–
IM0
2
22 – Bus Interface Board”.
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. 4.9.3-3) 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 RPA Parallel System must be
performed only by an ABB Service Technician.
