120 V and 240 V Equipment Designated for
U.S. Markets
Note: If you are not installing this equipment in the United
States or Canada, this section does not apply to you. You
should have received a power cable that meets your local
electrical code requirements along with the equipment. If you
need additional help with the power connections for the
equipment, contact your Precor authorized dealer.
Precor exercise equipment that is connected to an external
power circuit, such as treadmills or equipment with optional
power supplies for self-powered equipment, must be properly
grounded. In addition, Precor treadmills must be connected to
a dedicated branch circuit for power. A 20 amp dedicated
branch circuit is recommended.
Important: A true dedicated branch circuit provides discrete hot,
neutral, and ground lines to each plug. These lines must not be
looped or "daisy-chained" to any other lines in any way.

8Assembling and Maintaining the RBK 815 Recumbent Exercise Bike
For equipment fitted with P80 consoles or Personal Viewing
System (PVS) screens, separate power connections are
required for the consoles or screens. This connection must be
independent of the circuit powering the equipment and must
also be a dedicated branch circuit. However, up to 15 consoles
or PVS screens can be "daisy-chained" on a single power
circuit. A 20 amp dedicated branch circuit is recommended
for every such chain of consoles or screens.
The grounding plug on a treadmill or power supply looks like
the plug shown in one of the following two figures. The power
outlet must have the same configuration as the plug.
Important: Do not use any power cord adapter with this product.
