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 unrestricted airflow in and around
the unit. Provide at least 4
″ around the fan of the DLS to allow for
proper air intake.
DO NOT mount the unit in a zero clearance compartment.
DO NOT mount the DLS in the same compartment with flammable
items such as gasoline or batteries. There are no components
within the DLS 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 in an area that has the potential of dust,
debris, or other foreign materials to enter in through the DLS vents.
DO NOT place the DLS directly above the battery; the gases from
the battery can corrode and damage the DLS.
bATTERY CONNECTION
Before you connect the DLS 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. Con-
nect 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. Recommended wire gauge and torque
are as follows: 4-6 AWG at 45 in. -lbs, 8 AWG at 40 in. -lbs. 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 “Chassis 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. Refer to Illustration 2 for specifications of the
cord provided with your DLS unit. See the Technical Specifica-
tions Chart on page 4 for maximum current draw and required
input voltages.
DO NOT USE EXTENSION CORDS - Using an improper exten-
sion 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 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. 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. Apply 8 inch-pound
maximum torque. DO NOT OVERTIGHTEN. Note: some DLS
models require only one fuse. For these units, a small fiberglass
spacer may be used in the empty fuse slot to aid with tightening.
IOTA DLS 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 Power Converters/Battery Chargers are war-
ranted from defects in materials or workmanship for two
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 com-
plete warranty details, contact Customer Service or visit
