Place and fix the cables
JA-1/2/3/4/5/6/7
and
JB-1/2/3/4/5/6/7
inside the UPS cabinets in the
position illustrated in the drawing.
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-1/2/3/4/5/6/7
and
JB-1/2/3/4/5/6/7
connecting the units should
be run in separated protected conduits (as indicated in fig. 4.11-4) 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 service engineer from of your
Service Centre
.
