TE-CD-TSP 37 Operations Manual
VFC+ CONNECTIONS
The descriptions of the various connections to the VFC+ control unit are described below.
“Motor”
The “Motor” power connection supplies power to the motor being controlled by the VFC V+. Both
Brush-Type and Brushless-Type motor are supported, but only one may be used at a time. The VFC+
will come configured to match the motor type ordered. THE MOTOR USED WITH THE VFC+
MUST MATCH THE AC POWER BEING SUPPLIED TO THE VFC+. THE VFC+ CONTROLS
CAN NOT CHANGE THE OPERATING VOLTAGE OR THE FREQUENCY OF THE INCOMING
POWER THAT IS SUPPLIED TO THE MOTOR.
“Power”
The “Power” connection supplies power to the VFC+. It should be connected to the AC power line.
Operation at both 120 Volts AC and 240 Volts AC are supported. The system is designed to operate at
either 50 or 60 Hz without the need to change the configuration of the unit. However, a jumper inside
the VFC+ determines the voltage on which the unit operates. DO NOT APPLY 240-VOLT POWER
TO THE VFC+ WHILE THE UNIT IS CONFIGURED FOR 120-VOLT OPERATION. THIS
WILL DAMAGE THE UNIT. APPLYING 120-VOLT POWER TO THE VFC+ WHILE THE
UNITS IS CONFIGURED FOR 240-VOLT OPERATION SHOULD NOT DAMAGE THE UNIT,
BUT IS NOT RECOMMENDED OR SUPPORTED.
“Ambient” Pressure
The “Ambient” pressure port is used to make the Pamb measurement. It should be left open to
atmosphere so that it properly senses the ambient pressure.
