3.2.2 input and output line without neutral
If the input line and the load are three-phase without neutral type (and only in this case), a kit to create
the signal neutral (optional) may be used. The kit may only be used by a specialized technician.
BATTERY CABINET if present:
The battery cabinet must
be provided with a sectioning device to be connected to the UPS.
This disconnector must
be closed only when the UPS is started up regularly. During connection to the
UPS the disconnector must
stay in the open position.
Up to 5 battery cabinets can be connected in parallel, in accordance with the diagram below.
Cabinet disconnector
For systems with 3 or more battery cabinets (up to 5 units), use a cabinet with a disconnector where the
cables can be parallel-connected (refer to the marketing department). For the sizing of the cables and
connection procedures, refer to the “INSTALLATION DRAWING” attached to the battery cabinet.
For back-up times requiring a greater number of Battery cabinets, contact the marketing department.
