Electrical Systems - Grand Design Reflection Fifth Wheel 150 Series Owner's Manual

Electrical Systems

Your Reflection Fifth Wheel is equipped with two independent
electrical systems. One system is 120-volt 60hz AC power, the
other system is 12-volt DC power. The electrical equipment and
associated circuitry are engineered into a dedicated system
specific to your RV. All installations meet or exceed industry
standards applicable on the date of manufacture.
• A hazardous condition may result from changes or
additions to RV electrical system made after delivery.
• Adding fixed appliances or making unauthorized
changes is NOT recommended.
• ONLY a qualified electrical technician should perform
service or modifications on the RV electrical system.
The methods, components, and materials used MUST be
in compliance with current safety and code requirements.
Please consult your dealer's service department for assistance.
Electrical System Maintenance
• ALWAYS disconnect the negative 12-volt DC
battery terminal and the shore power cord
BEFORE working on the electrical system.
• ALWAYS turn OFF the power converter,
BEFORE disconnecting the battery.
For more information on your RV's electrical system, See the
component manuals in your Owner Information Package.
30-Amp or 50-Amp Power Cord
The power cord (or shore power cord) connects your RV
to an external power receptacle. This heavy duty cord has
a dual purpose. When connected, it will :
• CARRY VOLTAGE & CURRENT to your RV
from the external power receptacle, and
• GROUND the electrical system of your RV
through the external power receptacle.
BEFORE connecting your power cord, ALWAYS:
• TEST the external power receptacle or electrical box with
a Line Monitor / Outlet Tester (customer supplied).
• DO NOT connect the power cord if the Line Monitor
indicates REVERSE POLARITY or an OPEN GROUND.

WARNING
Use caution when using
metal tools. If a tool makes
contact with a battery
terminal or the metal
connected to it, a short
circuit could occur which
could cause personal
injury, explosion or fire.
WARNING
The power cord MUST be
fully extended when in use
and NOT left coiled in the
electrical compartment or
on the ground.
If the power cord is left
coiled, it may potentially
create enough heat to melt
its protective casing.
