3.3.3 Mounting the customer unit
NOTE
Installation must be carried out by qualified personnel only, paying particular attention to safety
and warning instructions.
Sequence:
1 = Switch off the mains voltage, observe the waiting period.
2 = Undo the fastening screws on the frequency inverter and remove it from the motor.
NOTE
When removing the frequency inverter, note that the capacitor discharge time of 90 seconds
must be waited for and that no contact should be made with the underneath of the frequency
inverter!
3 = Place the CU so that the drill holes approximately match. Press the PCB into place by putting pressure on
to the plastic cover until it clicks into the PCB holders.
(When removing, press the PCB holders back with one hand and lift the CU out with the connection
terminal block.)
4 = Insert fastening screws
(This creates a PE connection, no further connection is required).
5 = Make necessary connections.
6 = Replace frequency inverter and tighten screws.
