fused protection between the battery and any device
attached to the battery terminal BUS.

Each battery terminal bus features four wire-terminal
connections. Two terminals allow a charging device
(such as CH200 or Sunsaver-10) to be attached to the
battery while providing protection with a 14 A fuse. The
remaining two terminals connect to a datalogger, or other
device, with a 5 A fuse. Refer to the diagram below
when attaching wires to the battery terminal bus.
1. Attach a 4386 battery terminal bus stuffed circuit
board to each terminal on the battery. Orient the
battery terminal bus as shown.
2. Use a red wire to connect the battery charger (+)
terminal to the CHARGE terminal on the positive
battery post.
3. Use a red wire to connect the datalogger or other device to the LOAD terminal on the positive
battery post.
4. Use a black wire to connect the battery charger (─) terminal to the CHARGE terminal on the
negative battery post.
5. Use a black wire to connect the datalogger or other device to the LOAD terminal on the negative
battery post.
NOTE: Use 18-AWG wire for all connections. PN 28490 includes an 18-AWG red wire and an 18-AWG
black wire (1 ft each).
