Connecting Main Power Wiring

The FloBoss 100-Series accepts input voltages from 8.0 volts to 28 volts
at the charge terminals (CHG+ / CHG-) with no external current
limiting (internal current limit is 200 mA). The maximum power for
DC voltage sources is 130 mWatts for the FloBoss 103 and 300
mWatts for the FloBoss 104, not including battery charging.
The terminals are labeled CHG+ for positive power connection (Battery
8.0 to 28 volts power) and CHG- for negative power connection
(Battery Common) on a label on the termination board. Refer to Figure
3-3.

Notes
▪ The terminal block for power (CHG) is located at the bottom of the
right-hand column. In earlier versions of the FB103, the terminal
block may have other locations.
▪ Check the label for the pin location of the CHG+ and CHG-
terminals carefully. If the positive and negative connections are
reversed, the internal batteries will not charge.
