2.3.3Battery Circuit Breaker Control Interface

J10 is the Battery Circuit Breaker (BCB) box interface.

Table 3 BCB control interface

Position	Name	Description
J10.1	DRV	BCB Driver Signal
J10.2	FB	BCB Contact State
J10.3	GND	Power Ground
J10.4	OL	BCB On-Line - Input - This pin will become active when
		BCB interface is connected. (N.O.)

NOTE

All auxiliary cables of terminal must be double-insulated. The wire must be 600V, 18-16 AWG stranded for maximum runs between 82 and 197 feet (25-60m), respectively.

2.3.4Output Dry Contacts

There are three output dry contact relays at the X1 slot (see Figure 8 and Table 4).
