Engel MT45F-U1D-P User Manual

4
IMPORTANT:
WIRING
Never use wiring less than AWG #12 between the battery and refrigerator.
HARDWIRING
When hardwiring your refrigerator to a battery, make sure there is a 10 Amp fuse for
MT35F-U1D-P and MT45F-U1D-P inline on the positive wire.
BE SURE THE POWER SUPPLY POLARITY IS CORRECT
In the event that the green refrigerator light fails to glow, inspect the power source
for proper voltage and correct polarity. The inner contact point of the DC Cord /
Plug must be positive and the outer contact negative (ground).
REDUCE RADIO NOISE INTERFERENCE – CONNECT REFRIGERATOR DIRECTLY
TO THE BATTERY
Reducing radio noise interference can be accomplished by twisting the power supply
wires together, attaching them directly to the battery and adding a 10 Amp fuse for
MT35F-U1D-P and MT45F-U1D-P near the positive battery connection. Avoid
splicing other devices into this circuit as interference may occur.
BATTERY CHARGERS
Never hook the refrigerator directly to a battery charger. It must only be attached to
a battery.
OPERATING YOUR REFRIGERATOR USING A PORTABLE GENERATOR
The internal refrigerator power supply unit may be damaged if powered by older style
generators without automatic voltage regulation. The only acceptable generators to
use are those that are “inverter style” or those with over-voltage protection. Please
contact your ENGEL Dealer for additional instruction on safe use when powering
your refrigerator with a portable generator.
CAUTION : The use of an extension cord is not recommended.
