INTRODUCTION
This unit is a two stage, constant current
battery charger for charging nickel-cadmium
type rechargeable batteries. The charge
termination is by a 14 hours timer at which
time it will switch from the charge current to a
low rate current. A 6 feet long output cable
with a barrel plug is provided. There are two
indicators on the front panel. The orange light
indicates that the charger is in the charging
mode. The green light indicates that the
battery is fully charged.
ASSEMBLY INSTRUCTIONS
Loosen the screws on the charger output terminal
strip. Identify the polarity of the terminal strip ant
the output connector; both the charger housing
and the output cable are marked with “+” & “-”
symbols. Insert the two spade terminals under the
terminal strip screws and tighten. To prevent
accidental shorting, cover the exposed terminals
with the molded press-on terminal cover.
If using loose wires, insert stripped ends under washers. A cable having a shield may be
grounded to the bottom hole using a number 6-32 x ¼” machine screw.
OPERATING INSTRUCTIONS
Before using this battery charger, make sure it is compatible with your battery. Refer to
the ratings on the battery charger, the specifications in this manual, and your battery
documentation. Charge only nickel-cadmium type
rechargeable batteries; attempting to charge other
types of batteries may result in battery damage. This
unit is provided with a polarized barrel plug
connector. Make sure your battery connector is
wired to match the output connector.
CAUTION: This unit is not reverse battery protected except by use of the polarized
connector. Make sure your battery connector is wired to match the charger connector or
damage to the battery and charger may result when power is applied. While in a reversed
condition the charger will indicate that it is in the charging mode. However, it may
actually be discharging the battery until either the battery or charger is damaged.
