DC Input Power Terminal Block
The DC Input Power terminal block is where input power arrives within the G Series cabinet, passes through
fusing, and then continues on to the EMS through 15A fuses. The G Series operates on nominal 12-volts DC
power, which is provided either by a battery and solar panel in solar-powered systems, or an AC/DC power supply
in AC-powered systems. Note the polarity of the terminals which have been laid out to maximize the distance
between positive and negative and prevent accidental shorting.
Use the following table when connecting the solar panel harness to the Power Terminal Block:
Polarity
Positive (+)
Negative (−)
The Battery/DC Power side of the DC Input Power terminal block comes prewired from
Carmanah.
