Treadmill Base Operation

Power Entry

The GEN-06 / TRM10 base is equipped with a removable line cord plugged
into a power entry socket. This is designed to accommodate either 120V or
240V NEMA compatible line cords, as well as line cords for other
countries. The diagram below shows a NEMA 20A plug for both 120V and 240V
configurations in the United States.

120v power, when measured from hot to neutral, should read between 90 and
132v. 240v power, when measured from hot to neutral should read between
180 and 264v. This input voltage is applied through the power entry plug
and wired to the breaker switch. The 120v breaker switch only interrupts
the hot line and the 240v breaker switch interrupts both the hot and
neutral lines. The power is then fed through a line filter which removes
high frequency noise from the line voltage. After the power is cleaned by
the line filter it can be applied to the lower electronics module (IFT
drive).
