GE T2100 Treadmill

Theory of Operation: Electrical Requirements

Electrical Requirements

The two black wires that exit the side of the enclosure supply power to
the drive. The power source should be single phase, 200–240VAC, 50–
60Hz, 16A.

Maximum input current is 16A.

Fuses should be FLM 20A SLO only. Substituting a different fuse type
may cause a fire or safety hazard.

The orange wire from the side of the enclosure is connected to the
sheetmetal enclosure and should be connected to the designated terminal
on the power terminal block. Do not connect this wire to the GE T2100
Treadmill frame which would cause a safety hazard.

The motor wires exit through the flexible conduit on the left side of the
enclosure. These wires carry the pulsed 320V to the motor. Be sure to
observe proper phasing when connecting these wires. The drive will not
operate with incorrect phasing.

NOTE

If the motor is disconnected, do not let the motor wires short to each
other or any other point. If it rotates, the motor will function as a
generator, and it may be damaged or cause a shock hazard. The
drain wire should be connected to the motor frame. Make sure this
connection is secure.
