3. Before applying power, please ensure that all devices, including power, motor, control board, and digital keypad, are connected correctly.
4. When wiring the AC motor drive, ensure that the wiring of input terminals "R/L1, S/L2, T/L3" and output terminals "U/T1, V/T2, W/T3" are correct to prevent drive damage.
5. When power is applied, select the language and set parameter groups via the digital keypad (KPE-LE02). When executing a trial run, please begin with a low speed and then gradually increase the speed until the desired speed is reached.

Nameplate Information

The nameplate provides essential information about the AC Drive Model, Input Voltage/Current, Output Voltage/Current, Frequency Range, Firmware Version, Certifications, Enclosure type (IPXX), and Serial Number. Example: MODEL: VFD007CB43A-20.

Model Name Breakdown

The model name, such as VFD007CB43A-21, provides detailed information:

RFI Jumper

The RFI jumper can enable an internal filter to suppress Radio Frequency Interference (RFI) on the power line. It is located on the MOV-PLATE. Screw torque for the jumper is 8~10 kg-cm (6.9-8.7 lb-in.).

Isolating main power from ground: For floating ground systems (IT) or asymmetric ground systems (TN), the RFI jumper must be removed to cut off the path between the system's mechanical frame and the central circuits, preventing damage and reducing ground leakage current (according to IEC 61800-3).

Caution: Do not remove the RFI jumper while the power is on. Removing it cuts off the conductivity of the capacitor. Gap discharge may occur if transient voltage exceeds 1000V. If the RFI jumper is removed, electrical isolation is no longer reliable, and the drive may lose electromagnetic compatibility.

The RFI jumper may not be removed if the main power is a grounded system or during high voltage tests.

Ground Connection

Proper grounding is essential for safety, operation, and reducing electromagnetic radiation. Ensure the earthing cable meets safety regulations and is connected to the ground terminal. Do not connect grounds of multiple drives in series.

Floating Ground System (IT Systems)

Also known as ungrounded or high impedance grounding systems. Disconnect the ground cable from the internal EMC filter. If EMC is required, check for excess electromagnetic radiation. If in doubt, install an extra electrostatic shielded cable. Do not install an external RFI/EMC filter that connects power input to ground, as this can damage the drive.

Asymmetric Ground System (Corner Grounded TN Systems)

Caution: Do not cut the RFI jumper while the input terminal carries power. The RFI jumper must be removed in specific configurations (corner grounded, midpoint grounded, single-phase grounded, autotransformer) to prevent grounding through the RFI capacitor, which can damage the drive.

When using a symmetrical grounding power system, an EMC filter can be installed. The RFI jumper can be used in such systems to reduce electromagnetic radiation.

Main Power Terminals

Do not connect 3-phase models to one-phase power. R/L1, S/L2, T/L3 have no phase-sequence requirement. A magnetic contactor (MC) is recommended for quick power cutoff. Fasten main circuit terminal screws. Use voltage and current within specifications. When using GFCI, select sensitivity of 200mA or above with a 0.1-second operation time. Use shielded wire or tube for power wiring and ground both ends. Do NOT run/stop drives by turning power ON/OFF; use RUN/STOP commands. If power ON/OFF is necessary, do so only once per hour.

Output Terminals

For output filters, use inductance filters only. Do not connect phase-compensation capacitors or surge absorbers unless approved by Delta. Use well-insulated motors suitable for inverter operation.

Terminals for DC Reactor, External Brake Resistor

DC+ and DC- terminals are for connecting DC reactors to improve power factor. Remove the jumper before connecting the DC reactor. Brake resistors or brake units connect to B1, B2 terminals for applications with frequent deceleration or requiring increased brake torque.
