Chapter 1 Introduction|
CAUTION!
1. After applying power to the AC motor drive, do not cut off the RFI jumper. Therefore,
please make sure that main power has been switched off before cutting the RFI jumper.
2. The gap discharge may occur when the transient voltage is higher than 1,000V. Besides,
electro-magnetic compatibility of the AC motor drives will be lower after cutting the RFI
jumper.
3. Do NOT cut the RFI jumper when main power is connected to earth.
4. The RFI jumper cannot be cut when Hi-pot tests are performed. The mains power and
motor must be separated if high voltage test is performed and the leakage currents are
too high.
5. To prevent drive damage, the RFI jumper connected to ground shall be cut off if the AC
motor drive is installed on an ungrounded power system or a high resistance-grounded
(over 30 ohms) power system or a corner grounded TN system.
