About this task

Low-voltage wiring terminals are located underneath the front cover. See Figure 1, Table 1, and Table 2. After you finish making the low-voltage wiring connections, replace the front cover (Figure 1).

Terminal Label1 Signal Type Description
RH Contact Input Run High Speed
RM Contact Input Run Medium Speed
RL Contact Input Run Low Speed
MRS Contact Input Current Input Selection - Connect terminal MRS to terminal SD to enable the 4–20 mA input, Analog Input 2 (AI2).
RES Contact Input Reset - Turn on the RES signal (100 ms or longer) to turn off the VFD output and reset the thermal relay and regenerative brake circuits
SD Common Common for contact inputs (using Sink logic - default setting) and 24 VDC supply
AM Analog Output 0–10 VDC analog output corresponding to output frequency
PC +24V +24 VDC Supply
SE Open Collector Common Common for RUN terminal
RUN Open Collector Transistor Output VFD Running - Switched low (transistor conducts) when the VFD output frequency is higher than the start frequency (the motor is running). Switched high (transistor is off) when the motor is off.
FU Open Collector Transistor Output Frequency detection output - switched low (transistor conducts) when VFD output frequency has reached or exceeded the detection frequency. Switched high (transistor is off) when VFD output frequency is below detection frequency.
A Relay Output (N.O.) During normal operation, relay contacts A and C are connected. (maximum alarm load: 230 VAC, 0.3 A or 30 VDC, 0.3 A).
B Relay Output (N.C.) During normal operation, relay contacts B and C are connected (maximum alarm load: 230 VAC, 0.3 A or 30 VDC, 0.3 A).
C Relay Output (C) Relay output common
10 +5 V +5 VDC Supply for P499R transducers (15 mA maximum)
2 Analog Input Analog Input 1 (AI1) accepts 0–5 V or 0–10 V DC analog input signals
5 Analog Common Common for analog inputs
4 Analog Input Analog Input 2 (AI2) accepts 4–20 mA analog input signals
SD Common Common for contact inputs (when using Sink logic - default setting).
STF Contact Input Forward rotation. Must connect STF to SD terminal (common) using factory supplied jumper to allow VFD to rotate in a forward direction.
STR Contact Input Reverse rotation (not used)
SD Common Common for contact inputs (when using Sink logic - default setting).

Terminal Label Signal Type Description
5V +5V +5 VDC Supply for P499R transducers (15 mA maximum)
IN1 Analog Input Analog Input 1 for 0.5 to 4.5 V Ratiometric High Signal Select
GND Analog Common Common for analog inputs
5V +5V +5 VDC Supply for P499R transducers (15 mA maximum)
IN2 Analog Input Analog Input 2 for 0.5 to 4.5 V Ratiometric High Signal Select
GND Analog Common Common for analog inputs
1 Gray cells indicate a terminal that is typically not used in condenser fan speed control applications.
