If motors are connected without PTC thermistor or thermal switch,
cables 7 and 8 must be linked at the motor; otherwise the RA-SO
issues a fault message.

Warning!
If motors are used whose insulation is not suitable for
operation with RA-SP, the motor may be destroyed.
i Warning!
Risk of destruction of the motor through the RA-SP’s
frequency-controlled output if braking units or braking
rectifiers are connected directly to the motor’s terminals.
