IOTA DLS-54-13 - Manual (Page 2)

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.
Connect the positive (red) and negative (black) terminal lugs to
battery or load (lugs require a #2 square drive). 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 posi-
tive 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
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 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 5 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-48-20 Power Converter and DLS-54-13 Battery
Chargers convert 120 volts nominal A.C. to volts D.C. As a
power supply, the DLS-48-20’s 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 char-
ger, the DLS-54-13 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 de-
signed with high quality components to help ensure
years of continuous use. The unit is protected by multiple
protection features for a long, trouble-free life.
1) Reverse Battery Polarity Protection. 2) Brown-Out In-
put 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 temperature. 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
