5. Connect the solar panel harness to the CPU/System Controller
Board (TB1-1 = +, TB1-2 = GND).
6. Secure the battery via the battery clamp and connect the battery
power wires to the battery (Red = Pos., Black = Neg.).
7. When you are ready to apply power, plug connector TB1 into the
CPU/System Controller Board.
2.6 Power Distribution Board
If you use an external power source to provide bulk power to the unit,
you route power to various optional items through a power distribution
board. In this case, options such as the 24Vdc Loop Power Supply
board, Digital to Relay I/O Board or an external radio or modem,
require you to use the power distribution board. You mount the power
distribution board to the inside of the enclosure using a Snap Track that
is secured to a dual PCB mounting bracket.

2.7 Digital to Relay I/O Option
The digital to relay I/O board (see Figure 2-13) converts one or two
discrete output signals from open drain MOSFET levels to Form C relay
output signal using solid state relay (SSR) logic.
You can then configure the form C output signals for opposite or
identical conditions, such as both Normally Open (NO) or Normally
Closed (NC) or one Normally Open with the other normally Closed.
