Dedicated Branch Circuit
It is required that the treadmill be connected to and operated on a dedicated 20 amp AC
branch circuit. A Dedicated Branch Circuit is defined as a circuit fed by a single circuit breaker
feeding a single load, with a single non-shared neutral providing a return line. A treadmill oper-
ating from a non-dedicated branch circuit or a circuit breaker of less than 20 amps capacity will
not have the necessary power to operate normally under higher load conditions.
120 Vac Systems
120 VAC distribution systems utilize a single pole circuit breaker (power lead) and a neutral
lead connected to a common neutral (ground) bar. The AC. safety ground (green wire) is con-
nected to a separate ground bar in the distribution system.
If it is determined that any of the above electrical conditions are in question, please consult with
a qualified electrician to make appropriate circuit changes.
CAUTION: The treadmill requires a 20-amp individual branch circuit grounded per
NEC (National Electric Code) guidelines or local region electric code.
IMPORTANT: If the AC circuit feeding a treadmill is found to be a non-dedicated
branch circuit or a circuit equipped with a capacity of less than 20 amps, the AC circuit
must be corrected before any reliable Troubleshooting can be performed. More
importantly, a non-dedicated branch circuit may constitute a safety hazard to the tread-
mill operator .
Input Power
Nominal 120 VAC models
l Operating voltage: 90 VAC to 132 VAC.
l Frequency: 47 65 Hz
Nominal 240 AC Models
l Rated Operating voltage: 180 VAC - 264 VAC.
NOTE: An Internal operating voltage range of 180 – 275 VAC with reduced per-
formance is allowed.
l Frequency: 47-65 Hz
Frame Ground
For operator safety and to minimize electrostatic discharge conditions the AC frame ground
continuity must also be verified to be a low resistance connection to the AC distribution ground
bar.
