5.4.3 Frequency Inverter (18.5 to 30 kW)
The connection of the motor to the frequency inverter is to be done via terminal X2.
Danger! Switch off power supply before connecting or disconnecting the
motor cables to terminal X2. Dangerous voltage may be present at the
motor terminals and the terminals of the brake resistor even after the
frequency inverter has been disconnected safely from power supply.
Wait for some minutes until the DC link capacitors have discharged
before starting to work at the unit.
• The unit may only be connected with the power supply switched off.
• Make sure that the frequency inverter is discharged.
