REMOTE POWER RECEPTACLE INSTALLATION GUIDELINES
For SB Trailer Units with SmartPower™ Option
DANGER: An improperly installed remote power receptacle could lead to serious injury
or death! Only a qualified electrician should perform this installation.
DANGER: The remote power cable must be physically separated from the trailer’s fuel
lines. Fuel lines in the presents of an electrical short can result in a fire!
WARNING: Take precautions to ensure the unit will not accidentally start while you are
servicing the system.
CAUTION: The remote power receptacle and electrical wiring must be installed in such
a manner as to not interfere with the normal operation of the trailer.
NOTE: The power receptacle factory installed onto the unit is the preferred mounting
method. Alternative mounting methods are the responsibility of the installer.
• The installer is responsible for mounting the remote receptacle securely and safely onto the
trailer.
• The installer is responsible that all electrical wiring is safely installed and all connections and
grounds are made per the supplied instructions and wiring diagram.
• To prevent damage to the refrigeration units electric motor, the combined power cable length
from the unit to the power supply, must not exceed the recommendations shown in Figure 1.
• The installer is responsible for installing all supplied safety labels and meeting applicable
electrical codes.

the additional unit ground wire.
•
Remove any paint and debris from this area and drill the appropriate size hole.
•
Route the ground wire to the trailer’s chassis and attach it securely with appropriate (installer
supplied) hardware.

2. Open the curbside door and remove the access cover from the high voltage box.
•
From under the unit locate the flexible conduit at the rear of the high voltage box.
•
Route the power cable (installer supplied) through this conduit and into the high voltage box.
IMPORTANT: A water tight connection at the end of the conduit is required.

3. Route enough power cable into the high voltage box to make the electrical connections.
•
Strip 12 inches (304.8 mm) of insulation to expose the four individual wires. Secure the power
cable to the bottom of the high voltage box to the cable tie mount as shown.
•
Route the three power wires to the On/Off switch, strip the wire ends and install sleeve crimps
(installer supplied) firmly onto each wire.
•
Attach the wires to the On/Off switch per the supplied electrical schematic. See Figure 5.
IMPORTANT: Make sure the high voltage power wires do not rub against the low voltage
ground stud inside the box!
•
Neatly route and secure the power wires to the side of the box with the cable tie as shown.
•
Route the ground wire from the power cable up to the high voltage ground stud, strip the wire
end and install a terminal ring (installer supplied) firmly onto the wire.
•
Attach the high voltage ground wire securely onto the high voltage ground stud.
