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.
