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. Plug the connector
end of the temperature probe into J5 of the control unit backplane card. Route the cable
as required positioning the probe on the selected battery cell. Remove the adhesive
protection strip from the probe body and press the adhesive side of the probe on the
battery cell cover.
3.5. DC SYSTEM GROUNDING
The Positive Battery connection (return bus) for the power plant must be connected to the
Master Station Ground. The left end of the return bus provides a pair of threaded 3/8-16
holes on 1 inch (25.4 m) centers for connection of a two-hole lugged cable to the Master
Station Ground. Details for this connection should be provided in the site electrical
grounding plans.
