Appendix A: Charger assembly
Minor assembly is required. The distribution cable is packed separately from the charger
and must be connected to the terminals of the charger before use. You will need a Philips head
screwdriver for assembly. Follow these steps:
1. Identify the polarity of the terminals on the
cable as well as on the charger (see photos
on right).
†
2. Unscrew the terminal screws slightly and
insert the terminal forks
underneath
the
square washers.
3. Tighten the terminal screws with moderate
force. Do not overtighten.
4.
Put the plastic cap over the screw terminals to
prevent an accidental short. If the polarity is
reversed, the cap will not fit properly.
†
Do not connect charger with incorrect polarity to the dAck!, as this
will degrade and ultimately destroy the power cells.
Appendix B: Charger use
The indicator on the charger denotes the health status of the charger and battery. The
colors depict the state of the charger, and the condition of the batteries can be inferred by reading
this indicator.
POWER/FLOAT
– When the charger is plugged into the
AC mains with no cells connected, the indicator should be
green. When the power cells are connected to the charger,
this indicator also shows when the cells are float charging.
This is the healthiest condition and the dAck! should be
kept in this mode as often as possible.
†
FAST CHARGE
– When the charger is connected to depleted cells, they undergo
a rapid charge cycle. At this point, the indicator should turn yellow. The yellow
indicator will turn green when the charger enters float mode.
FAULT
– A red indicator denotes fault status. It indicates a grounding error,
batteries connected with incorrect polarity, or internal fault. If a red indicator
illuminates and you cannot determine the cause of the problem, please contact
Ack!Industries for help.
†
Technical note: When the indicator switches from yellow to green, the cells are not 100% charged. In actuality,
the charger switches to float status at about 90% capacity and gradually ramps the cells to 100% over a long period
of time.
