Appendix D: Solar Power Mode Specification
The Solar Power Mode behaves in a different way than the standard version:
There are two sets of batteries in a solar unit:
1.
S
OLAR
B
ATTERY
B
ANK
: The
solar array
provides power to the unit when there is
adequate sunlight. During periods of inadequate sunlight, power is supplied by a
large solar battery bank.
2.
RTU
B
ACKUP
B
ATTERY
: The RTU still has its own backup battery, although there
are two of those same types of batteries.
To conserve power, LEDs will flash at a slow rate (22Hz)
Power Failure occurs due to solar battery bank discharge instead of AC power
Circuitry controlling POWER-ON after total battery discharge, included hysteresis to
reduce oscillation. Battery discharged threshold changed to allow charging without
turning on the unit
The input power connector, labeled as “TB1 – POWER IN & REMOTE A/D” shown with the
large gauge wires coming from the SunGuard regulator on the left, is shipped
DISCONNECTED. The wires have been pulled off its mating connector on the RTU circuit
board. These wires must be plugged in, to connect primary power to the unit (which for the
solar unit is the solar array and solar battery bank).
The battery disconnect jumper (see “Chapter 2.0,
Connecting the Battery”) must be moved from the right-
hand position to the left-hand position when the RTU is
placed into service.
If the RTU needs to be taken out of service for an
extended period or returned to RACO for service, you
need to remove the wires from TB1, and also move the
battery jumper shunt (JP6) to the right-hand position to
disconnect the battery.

specifications, please refer to the following drawings and
mounting diagrams, or contact your RACO
representative.
