Power Requirements - XTM DFR4020XTM Quick Start Manual

PO WE R RE Q U I R EMEN TS
The fridge is designed to operate on DC voltage.
+ DC input 12V or 24V DC (e.g. car cigarette
lighter or car battery).
+ If the fridge is operating when the vehicle
ignition is switched OFF, the fridge will switch
OFF automatically when the power source
voltage falls below the Battery Protection cut-out
setting.
+ The fridge will automatically switch back ON when
the vehicle is re-started and the power source
voltage reaches the Battery Protection cut-in
setting.

+ Plug the 12V/24V DC power cord into the DC
power socket (as highlighted over page) on the
end of the fridge and then connect to the vehicle
cigarette lighter socket or suitable 12V or 24V
DC power source.
+ The fridge will automatically turn on, there is no
requirement to switch the appliance on.
+ The display will automatically show the current
internal cabinet temperature.
+ For optimum performance and efficiency, it is
important that the fridge has a reliable DC power
source available. Direct connection to the battery
is recommended and reduces the risk of voltage
dropping to the appliance.
+ Use only the 2.5m DC power cord supplied with
the fridge.
IMPORTANT: If a DC extension cord is required
we recommended, as a minimum, use a 6mm dia.
(AWG11) 4.58mm2 Twin Sheath Two Core cord
with direct connection to the positive and negative
battery terminals with 15A inline fuse protection.
+ The fridge is equipped with an electronic control
system that will prevent polarity reversal. In the
event that the battery connection is reversed
the unit will not start or operate. The power
input socket is fitted with a 15A blade fuse for
protection.

REQ UIREM ENT S
If your fridge is cutting out prematurely, it could be
due to:
1. The low voltage protection being set too
high on the Battery Protection.
2. DC power cord and/or connections are
not suitable to carry the required current.
Check the power cord and all connections
and adjust the Battery Protection on the
control panel.
+ The fridge is equipped with a multi-level Battery
Protection that protects your vehicle battery
against excessive discharging when the fridge is
connected to 12V or 24V DC power source.
IMPORTANT: When using the fridge with DC power
supply, we recommended setting the Battery
Protection to LOW.
NOTE: A battery charger may only be connected to
the battery when the fridge has been disconnected
from the DC power source.
+ Over-voltage may cause damage to the
electronics of the fridge.
+ Your fridge is equipped with reverse polarity
protection. It protects your fridge against reverse
battery connection and short circuit.
+ As a protection for your battery, the fridge
switches OFF automatically if the power source
voltage is insufficient.
NOTE: It is important that the correct cord size and
gauge is used for the installation of the DC supply
as over distance the voltage can decrease if the
incorrect cord size and gauge cord is being used.
+ Always consult a qualified automotive electrician
when using a DC extension cord.
