Power ports
The RMC has two ports supporting two power connection options or modes. Select one of the following
modes:
–
Battery mode: a 12 volt Seal Lead Acid (SLA) battery with a charger supplies power.
–
External power mode: an external power source supplies power.
Table 2-10
provides the power port or terminal specifications and
RMC. The BAT port connects to a battery. The CHARGER/EXT PWR connects to either a charger or an
external power source, depending on the power mode.

Terminal type
BAT
Removable terminal connector (2 POS), screw termination. Wire gauge 12 AWG to 22 AWG
CHARGER/EXT
Removable terminal connector (2 POS), screw termination. Wire gauge 12 AWG to 22 AWG
PWR
IMPORTANT NOTE: Select wire gauges based on the voltage and current requirements of the
circuitry and the expected length of the wires. The gauge differs for each application.

Figure 2-11
illustrates an example of the connections for the battery mode when a solar panel is the
charger. The battery connects to the BAT port, and the solar panel connects to the CHARGER/EXT
PWR port. In this configuration, the solar panel powers the controller during daylight hours and
recharges the battery when the battery power is low. During nighttime hours, the battery supplies the
power.
