Important Safety Instructions Continued
9. PREPARING TO CHARGE
a) If necessary to replace an onboard charger from its mounted location, disconnect AC
power and remove DC charger cables at the battery to avoid possible arcing.
b) Be sure the area around the charger and batteries is well ventilated while the batteries
are being charged. Gases can be forcefully blown away using a piece of cardboard or
other nonmetallic material as a fan.
c) When cleaning battery terminals wear full eye protection to prevent corrosives from
coming in contact with eyes.
d) For Flooded (Wet) Batteries, add distilled water
(not tap or bottled water that contain
minerals)
in each cell until electrolyte reaches the levels specified by the battery
manufacturer. Do not overfill. For batteries without caps, carefully follow manufacturer's
recharging instructions.
e) Study all battery manufacturer’s specific precautions such as removing cell caps while
charging and recommended rates of charge.
f) Determine battery voltage by referring to the original equipment / operations manual
and make sure that the output voltage selector switch is set at correct voltage. If charger
has adjustable charge rate, charge battery initially at lowest rate.
10. CHARGER LOCATION
a) Refer to the installation section of this manual for installation of your battery charger.
b) Never place the charger directly above the battery(s) being charged; gases from battery
will corrode and damage charger.
c) Never allow battery acid to drip on the charger when reading specific gravity or filling
battery.
d) Choose a mounting location that provides adequate convection and ventilation.
e) Do not set the battery(s) on top of charger.
AC Grounding Instructions – The AC power cord includes a ground connection. Do not
remove this connection under any circumstances.
This battery charger should be installed so that it is not likely to be in contact with non
factory service personnel.

Applying AC Power
Apply AC power, battery type LED will turn on to indicate the battery type selected as
determined by the selector switch shown on page 7. The charging LED will illuminate
until proper voltage is achieved. Next, the Charging LED will turn off and Conditioning
LED will illuminate. The Conditioning LED will turn off after 2-6 hours depending upon
the selection of the absorption timer switch shown on page 8. After absorption mode
is complete the Ready LED will illuminate. In Ready mode your batteries are fully charged
and are being maintained at optimal battery voltage and will supply DC power for any
load up to the maximum output of the charger.
Note: for your safety the charger is equipped with an internal temperature sensor that
will shutdown the charger in the event of an overtemperature condition.
Note: your ProTech-C charger is equipped with a fan, the fan will only run when needed.
The fan is temperature controlled and will only turn on when cooling is necessary.
All Installations should be made in accordance with this manual and the certifications
pertaining to this product. Cable lengths and conductor sizes which may be desired
and are outside of those referenced in this manual must be in accordance with the
National Electrical Code and any other appropriate nationally recognized standards.
