| Installation 3.2.4 Residual current devices Only universal (type B, B+) RCD protective devices are permitted. Like frequency inverters, RCD protective devices cannot provide personal safety while operating the device, pulse charge currents from the capacitors in the integrated EMC filter lead to the RCD protective device triggering without delay.

• The direction of rotation should correspond to direction-of-rotation arrow (3 phase). • Smoothness of motor operation, (no abnormal noises). Sound levels exceeding 70 dB(A) may occur depending on size (see www.systemair.com for detailed information). Alarm output The fan motor has built in protection for locked rotor, which implies that the motor tries to restart with a pre-pro- grammed interval whenever it senses that the rotor is standing still.
