Safety Requirements For Installation; Electrical Wiring - Samsung DE6612-D Service Manual

2. Microwave Oven Installation Requirements (continued)

Safety Requirements for Installation:

The operating voltage should comply with the voltage
specified in the label of the microwave oven type attached
to the back of the appliance.
WARNING
This appliance is equipped with a capacitor. To
remove or relocate the appliance, take the battery out
and wait for about 20 seconds, and then disconnect
the power cable connections. If the power cable is
disconnected too soon, it may cause an electrical
short circuit and discharge (spark).
It is a good idea to install an additional safety fuse to a
positive(+) power cable. If the connection power cable is
damaged or causes a short circuit, it means that the safety
fuse can no longer prevent the appliance from being
dam-aged (cable fire). The safety fuse should be installed as
close to the battery as possible.
If the electrical cabling is not performed properly, it may
cause an electrical short circuit, resulting in the following:
Battery power cable may catch fire.
Airbag may burst.
Controller may work improperly.
An electrical component may malfunction. (Signal
lamp, Brake lamp, Horn, Ignition, Lighting, etc.).
To eliminate the danger of an electrical short circuit,
always disconnect and isolate the battery negative terminal
before using an electrical device in the vehicle. Also, in the
case of a vehicle equipped with an additional battery,
disconnect and isolate the negative(-) battery power cable.
Precaution
When disconnecting and isolating the negative battery
power cable, all the data stored in the memory
of the vehicle's system will disappear.
Depending on equipment included in your vehicle, you
may have to enter the following data again:
Ex) Vehicle audio password, vehicle clock, seat location,
panel computer, and time switch.

Electrical Wiring

Connection the power cable.
Do not pull Power Cable forcibly.
Do not t connect to a power supply other
than 24V.
Comply with the minimum diameter of the
power cable as specified in the manual.
Fasten the power cable properly.
Install the power cable properly to prevent
tripping over it.
Install the power cable properly to prevent
damage.
Use one red (positive/+)and one black
(negative/-)power cable to avoid confusion.
Battery
WARNING
Improper connection of power cable
wires (+,-polarity) causes the main fuse
or safety fuse to disconnect in the
microwave oven. Be sure to connect +,
- polarity in the proper way.
Connect the power cable securely.
If not, the oven may not function correctly and
could cause damage to the vehicle.
Be sure to connect the cable with proper torque
(30~50kg.cm)
Connect the oven to the user's battery (a
secondary bat -tery)if possible. Connecting to the
starter battery may overload the appliance, which
in turn may cause the engine to not turn over.
Make sure there is sufficient Battery
Capacity. The battery capacity should be 45Ah
for 24V operating voltage.
Power Cable Size and Power Cable
Length
For a 3m(118.1 inches) wire, the size should be a
minimum 22mm
voltage.
For a power cable more than 3m(118.1 inches) in
length,the size must be larger in order to reduce
the voltage drop.
If the voltage drop is too much, the oven may not
operate properly.
If you have used the microwave oven for
longer than 10minutes, keep your vehicle's
engine running for 2~3minutes to avoid battery
drain.
