Pay particular attention to the following points:
After turning on the main power, do not remove the RFI jumper while the power is on.
Make sure the main power is turned off before removing the RFI jumper.
Removing the RFI jumper also cuts off the capacitor electrical conductivity, the transient voltage surge
suppressor, and the common-mode capacitor. The Power Regenerative Unit no longer guarantees that
the electromagnetic compatibility conforms to regulations.
Do not remove the RFI jumper if the main power is a grounded power system.
Do not remove the RFI jumper while conducting high voltage tests. When conducting a high voltage
test to the entire facility, disconnect the main power and the motor if the leakage current is too high.
Floating Ground System (IT Systems)
A floating ground system is also called IT system, ungrounded system, or high impedance/resistance
(greater than 30
Ω
) grounding system.
Remove the RFI jumper to cut off the transient voltage suppressor and the common-mode capacitance
connecting to the ground.
When installing an external capacitor or an external EMI filter, you form a circuit through the
capacitor/EMI filter common capacitors’ grounding. That circuit might damage the capacitor and
the EMI filter.
In situations where EMC is required, install an EMI filter specially designed for IT Systems. Removing
the EMI filter might avoid damage but might also not conform to EMC regulations.
In situations where EMC is required, check for excess electromagnetic radiation affecting nearby
low-voltage circuits. In some situations, the adapter and cable naturally provide enough suppression. If
in doubt, install an extra electrostatic shielded cable on the power supply side between the main circuit
and the control terminals to increase security.
