ABB CPS6000 Product Manual page 143

Figure 12-4 shows the connections required if Reverse Polarity Protection is to be used with an external
disconnect switch. Note that the sense lead BATT1_SENSE or BATT2_SENSE must be connected as
shown in order for the reverse polarity protection feature to work. If two strings are being used,
connect one string to STATUS1, LVD1_COIL, STATUS1_RTN, BATCB1, and BATT1_SENSE connections and
the other to the "-2" connections. When more than two strings are being used, divide the strings
among the two inputs.
WARNING
When two battery strings are connected to the same battery terminal, care must be taken to ensure
the polarity of the two strings is correct to each other. Improper connection will result in one string
being shorted to the other string and the system can not protect against this.
With the above connections, the following alarms will be issued for the conditions noted. This assumes
the external disconnect switch is used to open and close the battery charging path to the batteries.
