CAUTION: The treadmill requires a 20-amp individual branch circuit grounded per
NEC (National Electric Code) guidelines or local region electric code.
Measure the AC input voltage with the treadmill running and no exerciser on the belt
l
"unloaded." Then repeat the voltage measurement "loaded", an exerciser on the belt
during the measurement. The difference between the two measurements should be
no more than approximately 6 volts RMS and ideally less:
If the voltage variance is more than 6 volts RMS, the distance from the outlet to

the power distribution panel circuit breaker may be to long or the wire gauge dia-
meter may be smaller than required. Request the facility to have an electrician
verity the circuit wiring from the outlet to the power distribution panel.
If NO, continue Troubleshooting.

Overloading is the most frequent cause of a tripped treadmill circuit breaker. Over-
l
loading is most often caused by worn belt/deck excess friction. The circuit breaker trip-
ping point can also be increased by poor input line voltage. Overloading most often
occurs with heavier exercisers running at high speeds, but never when lighter exer-
cisers are walking. Verify the deck and belt wear, replace as needed. The treadmill
tripped circuit breaker event is often accompanied by "Drive Motor Current Over-
loading" error codes 27, 28, or 29, see
If the treadmill ON/OFF circuit breaker is tripped:
