ProgressiveRC DLS-27-40 IOTA - Manual (Page 2)

TWO-STEP VOLTAGE JACK
The two-step voltage jack (located on the top of the DLS on the fan-end of the unit)
allows switching from a long-term float voltage to an increased quick-charge voltage.
When the included dual voltage plug is inserted in the jack*, the voltage increases for
faster charging. When the plug is removed, the voltage drops to rated nominal voltage
to reduce battery water loss.
WARNING: To avoid battery damage, remove the Dual
Voltage Plug when quick-charging is complete. NOTE: If the DLS is equipped with
an internal IQ4 smart charger, two-step charging is not needed and the Dual Voltage
Jack is disabled.
There are no components within the DLS unit that, in their normal operation, produce arcs or sparks. However, all
electronic devices have some potential for generating sparks in the event of failure. Therefore, never install this device
in the same compartment with flammable items such as gasoline or batteries.
INSTALLATION GUIDELINES
MOUNTING LOCATION
The DLS battery charger/power supply can be mounted in
any position within an enclosed or interior compartment.
Provide sufficient air space to allow unrestricted airflow in
and around the unit.
DLS INSTALLATION
Disconnect the positive side of the battery before installation.
Connect the positive (red) and negative (black) terminal lugs to
battery or load. Always use the proper size wire based on the
amperage of the converter and the battery. When connecting to
a battery, a breaker should be installed within 18” of the battery,
connecting the battery positive to the line side of the breaker,
and the DLS to the load side. Connect “Chassis Bonding Lug”
on the DLS to vehicle chassis or other grounding source.
120 VOLT A.C. INPUT
Plug the DLS A.C. input cord into a 120 volt 3 wire
grounded source. See chart for maximum current draw
and required input voltages.
REVERSE POLARITY FUSES
The DLS Battery Charger/Power Supply is protected
against reverse polarity on the DC output. If a battery
or the DLS is hooked up incorrectly, the fuses will blow
and can be easily replaced. Always use the same size
and style fuse that came with the converter. To change
the fuses, use a screwdriver to loosen the screws and
remove the fuses. Always replace the fuses with the
same type and rating. After inserting the new fuses,
tighten the screws firmly. DO NOT OVERTIGHTEN.
CHARGE CONTROL
THE IQ4 LED INDICATOR
(ONLY ON DLS MODELS WITH INTERNAL IQ4)
DLS Models with an internal IQ4 smart-charger give the user the benefit of automatic
Bulk, Absorption , and Float stage charging. This increases the charging capacity of
the DLS charger, decreases charge times and insures proper and safe battery charg-
ing without over-charging. The green LED on the fan end of the DLS will indicate which
charging phase the DLS unit is currently in. When the unit is first activated, the LED will
flash as it reads the number of cells in the battery. The unit will then proceed directly
to the Bulk charging or Float charging phase depending on the charge status of the
battery. Use the LED CODE TABLE for reference when checking the LED. Units that do
not have an internal IQ4 smart-charger can easily install an external IQ4 that plugs into
the available Dual Voltage Jack. Contact Customer Service for more information.
