RFI Jumper Configuration

The RFI (Radio Frequency Interference) jumper is crucial for EMC performance and surge protection.

• Varistors/MOVs are connected phase to phase and phase to ground to protect against surges.
• Removing the RFI jumper disconnects internal capacitors from ground, which can damage circuits and increase ground leakage current.
• If the drive has a built-in EMC filter, the RFI jumper connects filter capacitors to ground. Removing it can reduce the effectiveness of the filter.
• For single drives with built-in EMC filters, removing the RFI jumper may trigger a Residual Current Device (RCD).

To remove the RFI Jumper:

Diagram: Visual guide for locating and removing the RFI jumper for Frame A-F and Frame B-F models.

1. Loosen the screw and remove the RFI Jumper (as shown in the diagram).
2. Fasten the screw again after the RFI Jumper is removed.
3. For Frame B-F models (with built-in EMC filter), remove the RFI Jumper with a screwdriver.

Proper grounding is essential for safety and EMC compliance.

• Ensure the drive is properly grounded during installation.
• Cable diameters must comply with local safety regulations.
• Shielded cables must be connected to the ground of the drive.
• Shield of shielded power cables can only be used as the ground for equipment when the aforementioned points are met.
• When installing multiple drives, do not connect them in series; connect each drive to ground individually.

Important points regarding ground connection:

Diagram: Examples of correct and incorrect grounding setups for various AC systems.

Floating Ground System (IT Systems):

In an IT system (ungrounded system or high impedance/resistance), observe the following:

• Disconnect the RFI Jumper.
• Check for excess electromagnetic radiation affecting nearby low-voltagэлектрондук схемалар.
• If necessary, install an extra electrostatic shielded cable on the power supply side between the main circuit and the control terminals to increase security.
• Do not install an external EMC filter. The EMC filter is connected to ground through the filter capacitors, which can damage the drive in an IT system.

DC Reactor Installation

A DC reactor can improve power factor, reduce input current, and reduce interference. It stabilizes the DC-bus voltage. For 115V models, no DC choke is needed.

Diagram: Wiring connections for an optional DC reactor and brake resistor.

The DC reactor is installed between terminals +1 and +2. The jumper shown in the diagram needs to be removed before installation.

Эскертүү:

• It is recommended to install a protective circuit breaker to protect the system from damage.
• When a fault occurs, use the circuit breaker to shut off power.
• RB and RC are multi-function relay contacts.
