RISK OF EXPLOSIVE GASES
WORKING IN THE VICINITY OF LEAD-
ACID BATTERIES IS DANGEROUS.
BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL BATTERY
OPERATION. FOR THIS REASON, IT IS
OF UTMOST IMPORTANCE THAT YOU
FOLLOW THE INSTRUCTIONS WHEN
USING THE BATTERY CHARGER.
To reduce the risk of battery explosion, follow
these instructions and those published by the
battery manufacturer and review all Cautions
and Warnings associated with these products.

INSTALLATION GUIDELINES
MOUNTING LOCATION
The IOTA Power Converter/Battery Charger can be
mounted in any position within an enclosed or interior
compartment. Provide sufficient air space to allow unre-
stricted airflow in and around the unit. Provide at least 4″
around the fan of the DLS-X to allow for proper air intake.
IF USING AN OPTIONAL MOUNTING PLATE - Attach
the mounting plate to the mounting location prior to
attaching the unit.
DO NOT mount the unit in a zero clearance compartment.
DO NOT mount the DLS-X in the same compartment with
flammable items such as gasoline or batteries.There are
no components within the DLS-X unit that, during normal
operation, produce arcs or sparks.However, all electronic
devices have some potential for generating sparks in
the event of failure which can result in explosion or fire.
DO NOT mount the DLS-X in an area that has the
potential of dust, debris, or other foreign materials to
enter in through the DLS-X vents.
DO NOT place the DLS-X directly above the battery; the
gases from the battery can corrode and damage the DLS-X.
IOTA DLS-X Series Power Converter/Battery Chargers
convert 120 volts nominal A.C. to 13.6 volts D.C. As a
power supply, its tightly controlled regulation allows the
user to operate any 12 volt nominal D.C. load up to the
converter’s rated output current.As a battery charger, the
converter will maintain the battery, delivering its full-rated
current when the battery capacity falls sufficiently low.
The voltage is set to deliver its maximum current for the
necessary period of time that minimizes undue stress
to the battery caused by heating of its cells. This helps
to ensure the longest possible life of the battery. Over
time, as the battery nears its full capacity, the converter
will float-charge the battery to prevent self-discharge of
its cells.
PROTECTION FEATURES
The IOTA Power Converters/Battery Chargers are
designed with high quality components to help ensure
years of continuous use. The unit is protected by mul-
tiple protection features for a long, trouble-free life.
1) Reverse Battery Polarity Protection. 2) Brown-Out
Input Protection. 3) Over-Current Protection - cycle by
cycle peak limiting as well as rated current limiting to
maximize the life of the converter. 4) Over-Temperature
Protection. In addition, it is designed with a unique
“proportional” fan control circuit. Fan speed is directly
proportional to the converter’s internal ambient tem-
perature. This enables the fan to turn on and off very
slowly, minimizing unwanted fan-starting noise.
The IOTA DLS-X Series Power
Converters/Battery Chargers are
warranted from defects in materi-
als or workmanship for three years
from date of retail purchase, and
limits the remedies to repair or replacement.This warranty is
valid only in the continental United States and Canada. For
complete warranty details, contact Customer Service or visit

INSTALLATION GUIDELINES (cont.)
BATTERY CONNECTION
Before you connect the DLS-X to the battery, make sure that
the AC power cord is NOT plugged into an electrical outlet.
Disconnect the positive side of the battery before installation.
Connect the positive and negative terminal lugs to battery or
load. Always use the proper size wire based on the amperage
of the converter and the battery. Torque the connections to the
proper rating according to the wire manufacturer’s specifica-
tions. Refer to Illustration 1. Recreational vehicle applications
require a type III circuit breaker be installed within 18″ of the
battery, connecting the battery positive to the line side of the
breaker, and the IOTA unit to the load side. Connect “Chas-
sis Bonding Lug” on the IOTA unit to vehicle chassis or other
grounding source. Refer to Illustration 1.
120 VOLT A.C. INPUT
Plug the unit A.C. input cord into an appropriate 120-volt 3-wire
grounded source. The blue LED indicator light will illuminate,
indicating the presence of AC power. Refer to Illustration 2 for
specifications of the cord provided with your DLS-X unit. See the
Technical Specifications Chart on page 4 for maximum current
draw and required input voltages.
DO NOT USE EXTENSION CORDS - Using an improper
extension cord could result in a risk of fire and electric shock,
and may result in property damage, personal injury or death.
DO NOT OPERATE THE DLS-X WITH A DAMAGED CORD
OR PLUG. Have the cord or plug replaced immediately by
qualified service personnel.
REVERSE POLARITY FUSES
The IOTA Battery Charger/Power Supply is protected against
reverse polarity on the DC output. If a battery or the unit 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.
NOTE: Depending on the amperage model of the DLS-X,
fuses may not be present in all slots. Refer to the chart
below for the rating and number of fuses per model:

The DLS-X features an accessory port on the fan end of the unit for installing an IQ4-X Charge Control Module for automatic
four-stage charging.
Installing the IQ4-X Charge Control Module gives the user the benefit of automatic Bulk, Absorption, and Float stage charg-
ing. This increases the charging capacity of the IOTA charger, decreases charge times and insures proper and safe battery
charging without over-charging.The green LED on the module will indicate which charging phase the IOTA charger 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 initiate the
four-stage charging algorithms. The LED indicator will flash according to the active charging stage of the unit. Use the LED
CODE TABLE for reference when checking the LED.
To install an IQ4-X module into the charger, remove the fastening screw on the top of the port faceplate and detach the face-
plate. Plug the control module into the port and secure in place using the original fastening screw. NOTE: the port faceplate
and IQ4-X control module are similar in appearance. You can recognize the IQ4-X Charge Control Module by the presence
of the LED indicator on the face.
