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
inverter
• the in-phase connection of the motor
• 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!
• 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. ( 302)
•Activate the Brake resistor monitoring (I2xt)
if necessary. ( 303)
• C00015
must be used to select 87 Hz operation if a delta-connected asynchronous
motor (nameplate data: 400 V

/230 V

) is to be operated in conjunction with an
inverter for a mains voltage of 400 V.
