2.4.2 Connected or Stand-Alone Arrangement
For battery cabinets that connect to a Liebert UPS, (see Figures 3 through 12 ), cables will run from the positive
and negative busbars of the adjacent battery cabinet to the positive and negative DC connections of UPS. For
battery cabinets that are connecting to a Liebert junction cabinet (see
Figures 3 through 12 ), busbars will be
connected from the positive and negative busbars of the adjacent battery cabinet to the positive and negative
DC connections of the junction cabinet.
For systems with the cabinets bolted to each other but not connected to a Liebert UPS, the factory-supplied
cables can run internal to the cabinets.
For systems with the cabinets not bolted to each other, the cables must be run outside the cabinets. The
customer must supply all the interconnecting cables and hardware. For cabinets that are ordered as stand-alone,
the customer must supply all the interconnecting cables and hardware. See the UPS installation manual for
current ratings and recommended cable sizes.
2.4.3 Grounding
For cabinets that have been ordered as connected or attached, the ground cables and hardware will be supplied.
See
Figure 34 for location of cabinet-to-cabinet grounding.
For cabinets ordered as detached or stand-alone, customer must supply the cables and hardware. See the
terminal detail drawings for the ground busbar’s location.

During system commissioning, Vertiv Liebert Services will set the jumpers on the (External Interface Board) EIB and the
BIB. If another battery cabinet is added to the system after commissioning, it is imperative that Liebert Services reset the
jumpers on the EIB board and the BIB board.
