The wiring diagram presented in Figure 3b illustrates an alternative
wiring that can be used in some applications. Here the control circuit is con-
nected to the B+ and B- pins (in this example, Pins 1 and 10) instead of to the
battery pack. All four of the B+ and B- pins (Pins 1, 2, 10, 11) are connected
internally to the controller’s
B+, B- terminals. The pins are rated at 9 amps, so
this configuration is appropriate only for applications where accessory power
drawn from these pins will never exceed 9 amps.
Note: When using the B+ pins (10, 11) an appropriately sized fuse must
be added to the circuit to avoid damage to the controller.
