Control Terminal Configurations And Wiring - Emerson Unidrive HS30 Quick Start Manual

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
Only type B ELCB / RCD are suitable for use with 3 phase inverter drives.
WARNING
If an external EMC filter is used, 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.

Defaults are loaded before drive configuration changes are made.
Action will only occur if the drive is inactive, not in UU state 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.
