Below is the peripheral wiring of Goodrive310-UL series VFDs.
Note:
1. The VFDs of 220V (≤15kW) and 460V (G-type≤30kW, P-type≤37kW) are embedded with braking unit.
2. The VFDs of 220V (18.5–55kW) and 460V (G-type≥37kW; P-type≥45kW) have P1 terminals and are connected with external DC reactors.
3. The braking units apply standard braking units. Refer to the instruction of DBU for detailed information.

| Cables | Device to transfer the electronic signals |
| Breaker | Prevent from electric shock and protect the power supply and the cables system from overcurrent when short circuits occur. (Please select the breaker with the function of reducing high order harmonic and the rated sensitive current to 1 VFD should be above 30mA). |
| Input reactor | This device is used to improve the power factor of the input side of the VFD and control the higher harmonic current. The VFDs of 220V (18.5–55kW), 460V (G-type≥37kW, P-type≥45kW) and 575V have external DC reactors. |
| DC reactor | |
| Input filter | Control the electromagnetic interference generated from the VFD, please install close to the input terminal side of the VFD. |
 or | Braking unit or resistors | Shorten the DEC time The VFDs of 220V (≤15kW) and 460V (G-type≤30kW, P-type≤37kW) need braking resistors and the VFDs of 220V (18.5–55kW), 460V (G-type≥37kW, P-type≥45kW) and 575V need braking units. |
| Output filter | Control the interference from the output side of the VFD and please install close to the output terminals of the VFD. |
| Output reactor | Prolong the effective transmitting distance of the VFD to control the sudden high voltage when switching on/off the IGBT of the VFD. |
