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.
