Input power terminals. Connect to either a 3-phase 50Hz, 200Vac
power supply or to a 3-phase 60Hz, 200 to 230Vac power supply
for models Q2-2035 to Q2-2330.
Input power terminals. Connect to either a 3-phase 50HZ, 380Vac
power supply or to a 3-phase 60HZ, 400 to 460Vac power supply
for models Q2-4055 to Q2-420K.
Output load terminals. Connect these terminals to a 3-phase
induction motor of the proper voltage.

Output terminals of form C contact changes state when a protective
function has been activated (250Vac - 2A).
Output terminal for unregulated 24Vdc power supply
(100mA maximum output current).
Output terminal (open collector). Provides an output signal ground
(50 mAdc max) when the upper limit frequency is reached, when an
acc/dec is complete, or when the output frequency is within a specified
range. The choice is determined by settings of the Output Terminal
Selection function (:0.tb).
Output terminal (open collector). Provides an output signal ground
(50 mAdc max) when a preset low speed or a preset lower limit is
reached. The choice is determined by settings of the Output Terminal
Selection function (:0.tb).
Output terminal for an external analog frequency meter.
Use either an ammeter rated at 1 mAdc at full scale or a voltmeter
rated at 7.5Vdc at full scale.
Output terminal for an external analog ammeter.

Regulated 10Vdc power supply to be used with terminal RR for
remote terminal input.
Analog input terminal for a 0 - 5Vdc (JP2 @ 5V) or 0 -10Vdc
(JP2 @ 10V) external reference signal. Also used for wiring a Ik - 10k
ohm (3k ohm recommended) potentiometer to allow for remote speed
control operation.
Analog input terminal for a 0 - 5Vdc (JP1
(JP1 @ I) external reference signal.
