5.4.1 Frequency Inverter (0.55 to 4.0 kW)
The connection of the motor and the brake resistor to the frequency inverter is to be
done via plug-in terminal X2. Degree of protection IP20 (EN60529) is only
guaranteed if terminal X2 is connected.
Danger! Switch off power supply before connecting or disconnecting the
keyed plug-in 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.
