b. Connect station battery positive to terminal TB1-4 on the terminal block. Connect station battery
negative to terminal TB1-3. Connect chassis common to the center terminal on TB1 (the one
with the ground symbol beneath it).
If you have up to three fiber optic remotes at the same site, you can use the setup
shown in Figure 2-10 to drive two 9-volt remotes from the power supply in one
48-volt or 125-volt remote. To avoid large voltage drops in the connecting wires, this
method should only be used with fiber optic remotes that are near each other.
Long wire runs would drop the supply voltage to a level that is too low for reliable
remote operation.
