Connect the positive (red) and negative (black) terminal lugs to battery or load
(Disconnect POS side of battery if present before making DLS connections).
Always use the proper size wire based on the amperage of the converter and the
load. 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.
The unit features a cord with a three-prong IEC receptacle for connection to a prop-
erly rated C-13 input cord which connects to the 108-240VAC supply (not supplied).

DUAL VOLTAGE JACK
The DLS-UI-27-40 is equipped with a Dual Voltage Jack and
Dual Voltage Plug that allows manual switching from a long-
term float voltage of 27.2vdc to 28.4vdc. When the Dual Voltage
Plug is inserted in the jack, the voltage increases to 28.4vdc for
occasional fast charging. When the plug is removed, the voltage
drops to 27.2vdc to reduce battery water loss.
The Dual Voltage Jack also allows for easy installation of an
external IQ4 Smart Charger for automatic 4-stage charging
(optional). If the unit is equipped with an internal IQ4 smart
charger, two-step charging is not needed and the Dual Voltage
Jack is disabled. For details on 4-stage charging, refer to the
IQ4 instruction manual.
