■ Battery charging
DO NOT leave the battery charger on for more
than two days. The batteries might be severely
overcharged and/or damaged if the charger
fails to automatically turn off.
Keep all battery charger ventilation ports open
to prevent accumulation of explosive gasses
and heat.
1. Turn the Master Key Switch on the ground
control box to OFF and the Battery switch
(1) ON.
2. Set the Input Voltage switch (2) to 125 or 250
depending on whether you are going to plug
the battery charger into a 125 volt AC source
of power or a 250 volt AC source of power,
respectively.
3. Plug the battery charger (3) into a grounded
AC outlet (90 - 125/180 - 250 volt AC, 50/60
Hz), using a 3-conductor 12 gauge extension
cord that is in good electrical condition. Keep
the extension cord as short as possible.
The battery charger will start 3 to 5 seconds
after a complete electrical connection is
made.
4. Visually inspect the ammeter (4) for proper
charging rate.
● Initial charge rate will vary from 18 to 22 A
depending on how deeply the batteries
have been discharged.
● As the batteries become charged, the
ammeter will decrease to 5 A to 10 A
depending on the condition of the
batteries. Allowing the charger to finish at
this low rate is essential to equalize the
charge of all battery cells. Leave the
battery charger plugged in until it
automatically turns itself off.
If the batteries are already fully charged when
you connect the charger, the ammeter (4) will
initially jump to 15 A to 20 A then quickly
decay to zero.
If the ammeter (4) does not respond, check
the source of input power to be sure it is
turned on. Reset the 60 A circuit breaker (5) if
it has tripped. If the ammeter (4) still does not
respond, have a qualified service technician
check the input-power fuses (6).
5. After the battery charger has automatically
turned itself off, unplug the power cord.
