3.1 Safety instructions with regard to commissioning
General safety instructions
In order to prevent injury to persons or damage to material assets
• check before connecting the mains voltage
• the wiring for completeness, short circuit, and earth fault
• the "emergency stop" function of the entire system
• that the motor circuit configuration (star/delta) is adapted to the output voltage of the
controller
• the in-phase connection of the motor
• The direction of rotation or the encoder (if available)
• check the setting of the most important drive parameters before enabling the controller:
• the V/f rated frequency must be adapted to the motor circuit configuration!
• the drive parameters relevant for your application must be set correctly!
• the configuration of the I/O terminals must be adapted to the wiring!
• ensure that there are no active speed setpoints before enabling the controller.
Safety instructions with regard to motor operation

Danger!
The RFR control input is connected as default with a bridge to +24 V, which means that
the controller is enabled!
• This input can also be used for switching on/off the drive. For this purpose, the bridge
must be replaced by cabling.

Danger!
• For thermal reasons, continuous operation of self-ventilated motors at a low field
frequency and rated motor current is not permissible!
• In the Lenze setting, the Motor temperature monitoring (PTC) is activated. ( 176)
• In the Lenze setting, the Brake resistor monitoring (I2xt) is activated. The activation of
the monitoring function causes a switch-off of the braking operation. ( 177)
• With regard to the setting of the V/f base frequency ( C00015 ), observe the following
difference to the controllers 8400 StateLine/HighLine/TopLine:
In case of the 8400 motec, the reference voltage for the V/ base frequency is the rated
motor voltage ( C00090 ) according to the motor nameplate (independent of the
supply voltage).
