XTERNAL BATTERY TEMPERATURE PROBE
An optional temperature probe kit provides the USS3T - USS3M UPS with the ability to monitor the temperature within a separate
Battery Cabinet via the terminals located on the power terminal area, identified as “EXT T_BATT” (marked as 3 and 4, refer to the
“Power connection details” paragraph of the Installation manual for further information).
This
non-isolated
input can be used also to adjust the battery voltage in accordance with the ambient temperature (temperature
compensation) this feature must be enabled and configured via the configuration software (reserved to service personnel only).
When the probe is configured, the Ext-
Bat value will be shown on the “Sensor status” page.
It is essential that only the kit provided by the manufacturer is used. The use of a temperature sensor that does not
comply with the specifications may cause faults or failure of the equipment. Only authorised personnel can install and
activate the temperature sensor.
The kit enables the connection of a temperature probe for a Battery Cabinet placed adjacent to the UPS or up to 10
meters away. If this distance is insufficient then it is possible to extend it up to 25 meters.
To install the External Battery Temperature probe within the Battery Cabinet, refer to the manual provided with the kit.
