Residual current device
WARNING
Electric shock due to incorrect RCD type.
Severe or fatal injuries.
• The unit can cause direct current in the protective earth. In cases where an resid-
ual current device (RCD) is used for protection against direct or indirect contact,
only an RCD of type B on the power supply side of the frequency inverter is per-
mitted.
• Do not use a conventional RCD as a protective device. Universal current-sensitive
RCDs are permitted as a protective device. During normal operation of the unit,
earth-leakage currents of > 3.5 mA may occur.
