4.3.1 Use of residual current device (RCD)
There are three common types of ELCB / RCD:
1. AC - detects AC fault currents
2. A - detects AC and pulsating DC fault currents (provided the DC current reaches zero at least
once every half cycle)
3. B - detects AC, pulsating DC and smooth DC fault currents
• Type AC should never be used with drives.
• Type A can only be used with single phase drives
• Type B must be used with three phase drives
If an external EMC filter is used with an ELCB / RCD, a delay of at least 50 ms should be
incorporated to ensure spurious trips are not seen. The leakage current is likely to exceed the trip
level if all of the phases are not energized simultaneously.
4.4 Control terminal configurations and wiring
The setting of Pr 05 automatically sets the drive configuration.
Action will only occur if the drive is inactive and no User Actions are running. Otherwise, the
parameter will return to its pre altered value on exit from edit mode. All parameters are saved if this
parameter changes.
Only type B ELCB / RCD are suitable for use with 3 phase inverter drives.
