IMPORTANT SAFETY INFORMATION
INSTALLATION and OPERATING INSTRUCTIONS
SA Series Chargers (SA10012, SA17512, SA25012)
INSTALLATION
INSPECTION:
Inspect the charger immediately upon receipt. If
there is any damage, call the carrier for an
inspection and file a claim.
APPLICATION:
These chargers are designed to charge groups
of 12 volt batteries connected in parallel. Six
volt batteries may also be charged by
connecting two of them in series (making the
equivalent of a single 12 volt battery).
VENTILATION:
The chargers are designed for continuous duty
use and to provide reliability, the free air
circulation method of cooling is used, (no cooling
fan). Under the circumstances, chargers must
be installed in a well ventilated area and in a
manner so that air flow through the charger is
not restricted. Severe damage may result if air
flow around the cabinet is obstructed.
CAUTION: BE SURE TO DISCONNECT
CHARGER FROM AC SOURCE BEFORE
ENTERING CABINET
CONNECTION TO AC INPUT:
Model SA10012
Measure the voltage of AC power source
available. The charger model SA10012 can be
operated from a nominal 115 volt line (actual
operating range 105 to 125 volts) or a nominal
230 volt line (actual operating range 195 to 255
volts). Factory settings are at 230 volts AC. To
change the AC voltage setting, remove the front
panel and reconnect terminal board as shown
on the wiring diagram furnished with the charger.
Model SA 10012 is furnished with an AC power
cord. Attach a 115 V or 230 V A-C plug to fit
your requirements.
Models SA17512 and SA25012
Measure the voltage of AC power source
available. The charger can be operated from a
nominal 230 volt line (actual operating range 195
to 255 volts) or a nominal 460 volt line (actual
operating range 420 to 510 volts). Factory
settings are at 460 volts AC. To change the AC
voltage setting, remove the front panel and
reconnect terminal board as shown on the wiring
diagram furnished with the charger.
Models SA17512 and SA25012 are designed to
be conduit wired to the AC supply. Connect the
charger to the AC disconnect switch or circuit
breaker with the proper size wire (10 AWG for
230 volt supply, 12 AWG for 460 volt supply).
Remove the back panel and connect wires to
terminals L1, L2, and L3 (if applicable) and
ground on the terminal block mounted near the
AC input conduit fitting.
ADJUSTING DC OUTPUT
Chargers should be adjusted for proper DC
output at time of installation.
CAUTION: BE SURE TO DISCONNECT
CHARGER FROM AC SOURCE BEFORE
MAKING ADJUSTMENTS
SET VOLTAGE BETWEEN 14.8 - 15.2. The
end charge voltage (the voltage which the
batteries approach when fully charged) will then
be 14.4 to 14.8 volts. Batteries will be
recharged in the minimum length of time, require
a minimum of attention and with good batteries
there will be no excessive gassing or
overheating.
Models SA17512 and SA25012
Adjustment taps are provided internally, on the
same terminal board as AC input voltage setting.
With an accurate voltmeter, measure the DC
open circuit voltage (output voltage with the
charger turned on but without batteries
connected) at the ends of the DC cables.
If the voltage is too low, move the adjustment
leads to the right. If the voltage is too high move
the adjustment leads to the left. The coarse
adjustment lead should be moved first to set the
output voltage at or just below the desired
voltage (14.8 - 15.2V). Then move the fine
adjustment lead.
