Nominal AC operating voltage on 120VAC circuits is 90VAC to 132VAC.
Nominal AC operating voltage on 240VAC circuits is 180VAC to 264VAC. For
operator safety considerations 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.
Important
If the AC circuit feeding a treadmill is found to be a non-dedicated
branch circuit or a circuit equipped with a circuit breaker with a
capacity of less than 20 amps, the AC circuit must be corrected before
any reliable troubleshooting can be performed on the treadmill. More
importantly, a non-dedicated branch circuit may constitute a safety
hazard to the treadmill operator.
120 Vac Systems
120 VAC distribution systems utilize a single pole circuit breaker (hot
lead) and a neutral lead connected to a common neutral (ground) bar. The
A.C. safety ground (green wire) is connected 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.
