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 communication bus cables
J1A – J2A
(1/2/3/4/5)
and
J1B – J2B (1/2/3/4/5)
inside the UPS cabinet.
In case one unit must be removed from the
Parallel System
, the communication
bus cables must be taken out the UPS cabinet WITHOUT DISCONNECTING THEM
from the two boards
“P13/P14 – IM0022 – Bus Interface Board”.
For reliability reasons the cables
J1A – J2A (1/2/3/4/5)
and
J1B – J2B (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
J1A – J2A (1/2/3/4/5)
must be the same length as cable
J1B – J2B
(1/2/3/4/5)
.
WARNING !
Connection and commissioning of an additional UPS to an existing
Parallel System
must be performed by a service engineer from of your
Service Center
.
