1-5
1-6 RFI Jumper
RFI (Radio Frequency Interference): The Power Regenerative Unit generates electrical noise, resulting in
frequency interference on the AC power cable.
Frame A–C Screw torque: 6–8 kg-cm (5.2–6.9 lb-in.)
After loosening the screws, remove the RFI jumper (MOV-PLATE/ RFI jumper) as shown in the diagram
below. Make sure to tighten the screw again after removing the RFI jumper.
1-6-1 Isolating main power from ground
When the Power Regenerative Unit power distribution system is a floating ground system (IT) or an
asymmetric ground system (TN), you must remove the RFI jumper when using Delta’s EMI filter. Removing
the RFI jumper cuts off the internal RFI capacitor (filter capacitor) between the system's ground and the
central circuits to avoid damaging the central circuits and reduces the ground leakage current (according to
IEC 61800-3).
Important points regarding ground connection:
To ensure the safety of personnel, proper operation, and to reduce electromagnetic radiation, the
Power Regenerative Unit must be properly grounded during installation.
The diameter of the cables must meet the size specified by safety regulations.
The shielded cable must be connected to the Power Regenerative Unit ground to meet safety
regulations.
The shielded cable can only be used as the ground for equipment when the above points are met.
When installing multiple sets of Power Regenerative Units, do not connect the Power Regenerative
Units grounds in series, as shown below.
