Installation; Locating The Refrigerator - Norcold DE-541 Owner's Manual

Locating the Refrigerator

The refrigerator is to be located on a solid and level
floor that is strong enough to support the combined
weight of the refrigerator and its contents. Install the
refrigerator in area way from direct sunlight or other
heat generating sources.
AC Power Connection
WARNING
This refrigerator is designed to operate on 120 volt AC,
60 Hertz grounded circuit. The refrigerator AC power
cord is equipped with a three-prong grounding plug
which must mate with a three-prong grounding recep-
tacle to protect against possible shock hazards. Oper-
ating the refrigerator without proper ground can cause
property damage, severe personal injury, or loss of life.
It is the owner/installer's personal responsibility and
obligation to provide a properly grounded circuit to the
refrigerator in accordance with local codes or, in the
absence of local codes, the National Electrical Code,
NFPA 70. Do not cut or remove the grounding prong
from the refrigerator's AC power cord.
Route the 120 volt AC supplying the receptacle
through a fuse panel or circuit breaker which will protect
the vehicle when an outside power source is used. The
use of an extension cord is not recommended.
Notice: If AC power is supplied by an on-board generator,
it is important to maintain both the voltage and
frequency to within the specifications stated on
page 2.

DC Power Connection
To minimize the possibility of electrical interference
from other DC appliances, it is imperative that the
refrigerator has an independent 12 volt DC supply. The
12 volt DC connection is made by connecting the DC
power source directly from the battery to the refrigera-
tor. To further limit the possibility of interference and
induction due to voltage spikes, twist the 12 volt supply
wires from the battery to the refrigerator.
Do not use a converter or battery charger to supply the
DC power directly to the refrigerator. These two devices
do not supply filtered DC power. When using a con-
verter or battery charger, a battery must be in line
between these devices and the refrigerator. Refer to
Figure 14 on page 8 for correct wire routing.
The size or wire to be used for the refrigerator's power
supply is dependent upon the distance between the
battery and the refrigerator. Refer to Table 2 for the
recommended wire size. Undersized wire can lead to
a voltage drop which will greatly reduce the refrigera-
tor's performance.
TABLE 2
12 Volt Supply Wiring and Fuse Size
The DC supply connects to the refrigerator at the
3-Prong
terminal block of the power supply located at the rear
Grounding Type
of the refrigerator. The positive (+) supply lead con-
Wall Receptacle
nects to the red wire and the negative (-) supply lead
connects to the black wire of the refrigerator's power
3-Prong supply (refer to Figure 4 on page 5). Observe the
Grounding Plug correct polarity when connecting the DC supply to the
refrigerator. Route the 12 volt DC supply wires to
protect them from damage .
To protect the refrigerator's electrical circuit, install a
15 amp fuse or circuit breaker in the positive battery
supply lead as close to the battery as possible.
Disconnect the positive supply wire from the battery
before applying a "fast charge" to the battery. Failure
