Figure 18 Installing the UPS
Install the Battery Cabinets
Battery cabinets are installed the same as the UPS. Repeat the preceding procedures to install
the battery cabinets and a UPS in the rack, one at a time.
The battery cabinets weigh 11.5 lb. (52kg) each and require two people to install. The battery
cabinets should be installed first, beginning with the slots lowest in the rack. The UPS should be
installed last and placed above the battery cabinets.
NOTICE
Risk of improper transport. Can cause damage to the UPS or battery cabinets.
Never attempt to lift or move the Liebert ITA2 or battery cabinets with the rack brackets. The brackets
and screws are not designed to be used to lift the units.
NOTICE
Risk of improper installation. Can make rack top-heavy and cause a tipping hazard.
The battery cabinets are heavier than the Liebert ITA2 UPS. Vertiv recommends installing the battery
cabinets as near the bottom of the rack as possible to maintain a low center of gravity. Install the UPS
above the battery cabinets.
Each battery cabinet must be installed on its own set of rack-mount rails because the rail kit is not
designed to support the weight of more than one battery cabinet.
2.6 Connecting Power Cables
Input/output cables are required. When connecting the cables, follow the local wiring regulations,
take the environment situation into account and refer to NEC Table 3B of IEC60950-1.
The recommended minimum cable CSA is listed in
Tables 2 . Select the appropriate cables (see
Tables 2 and 3 ).
