Transformer option
The galvanic isolation transformer can be ordered as factory installed. The transformer is an
integral part of the UPS unit. Alternatively, the isolation transformer can be purchased as a
separate item to upgrade your existing system.
Figure 9. Transformer option can be ordered factory installed (integral) or separately.
The overtemperature sensor cable is connected to the control input (X45 or X44) of the UPS,
see the next drawing. In the factory installed systems this cable is ready-made for use.

External battery cabinet option
It’s recommended to install external battery cabinets next to the UPS unit. The external battery
can be placed on either side of the UPS unit. Check before the installation that the battery
voltage values in the type plate of the UPS and external battery cabinets are the same. The
cables are delivered with the external battery cabinet. See External Battery Cabinet (EBC)
installation procedure.
Warning!
The UPS contains high DC voltages. A qualified person must do the connections
between the UPS and the external battery cabinet(s). The battery cabinet is
connected electrically in parallel with the internal batteries of the UPS.

Battery racks
External battery racks shall be sized to take the voltage drop in the cable into account. To obtain
support and help contact the local office or agent authorised by the manufacturer.
