5.9 Battery Temperature Probe Installation
The optional temperature probe is used to monitor the battery string temperature. To get the most
representative temperature measurement, the probe should be placed in contact with a battery cell that
is centrally located. The probe should be placed directly in contact with the cell (not the frame
surrounding the cell). Generally, the cell cover can be used; be careful not to allow the probe body to
touch the terminals.
1) Plug the connector end of the temperature probe into J5 on the left side of the control unit
backplane card in the base power bay.
2) Route the cable as required to position the probe on the selected battery cell
3) Remove the adhesive protection strip from the probe body and press the adhesive side of the
probe on the battery cell cover.

removed.
