T External temperature sensor

The use of the sensor kit allows the UPS control logic to regulate
the battery maintenance voltage value in function of the internal
battery cabinet temperature.

.

It is necessary to use the specific kit supplied by the manufacturer only: any uses which do not comply
with the specifications may cause malfunctioning or breakage to the appliance.
