a.For NiCad and NiFe batteries, you must clip the R46 resistor and add 2 volts to the values
for BULK AND FLOAT shown on the circuit board. For example, set the BULK for
16.0 V adjust the BULK knob to 14.0 V after clipping R46. Values above are for batteries
at room temperature. For applications with significant temperature variations or systems
with sealed batteries, install a battery temperature sensor.
16.0 Vdc 14.5 Vdc Not
recommended.

Values shown are for 12-volt systems. For 24-volt Systems, multiply this
setting shown by 2. For 48-volt systems, multiply the settings shown by 4.
