PS100 and CH100 Power Supply and Charging Regulators
It is possible to leave two batteries connected. The battery connections are
diode isolated (Figure 2); however, if one of the batteries fail, it could draw all
the charging current and the other battery will be discharged.
A battery must be attached for the charger to function
correctly as a power supply.
CAUTION
The leads from the transformer or solar panel are connected to the CHG
terminals. Polarity does not matter; either lead can be connected to either
terminal.
The wires that connect power to the datalogger and/or peripherals are
connected to the +12 and ground ( ) terminals.
