3.4 BULK LOAD CONNECTIONS
Figure 3.9 Bulk Load Connections
A bulk load can either be a single large load, or a cable connection to an additional, external DC distribution unit.
There are two M6 studs available for securing either 2 cables with single-hole lugs or a cable with double-hole lugs.
Single-hole lugged cables will require additional cable tying to prevent the cable from rotating on the studs.
The positive and negative bars are always in the same position, regardless of whether the system is a 48VDC or a
+24VDC. In the case of the +24V system, the common return bar is connected to the (–) bus bar.
3.5 LOAD DISTRIBUTION CB TRIP SENSE CONNECTIONS
To enable monitoring and alarming of tripped external load distribution circuit breakers, a 3-terminal connector is
provided on the controller backplane - item (8) in Figure 2.. The signal is ACTIVE HIGH for any circuit breaker
going open circuit. Below is an example of how to configure external auxiliary contacts to interface to the line.
+15V and 0V is available on the connector to power active circuits if required. Note: the connection can be used in
parallel with load circuits in the battery/load distribution unit.
