Procedure
To connect up the inverter's terminal strip, proceed as follows:
1. Remove the last 10 mm (approx.) of the cable insulation.
2. Using the screwdriver, press on the orange operator control of the spring-loaded terminal
hard enough to open the terminal.
3. Insert the cable into the terminal as far as it will go and remove the screwdriver.
4. Ensure that the cable is securely connected by pulling on it lightly.
5. Connect up all of the required terminals on the terminal strip in this way.
6. Route the signal cables in such a way that you can completely close the front doors after
wiring the terminal strip.
7. If you use shielded cables, then you must connect the shield to the mounting plate of the
control cabinet or with the shield support of the inverter through a good electrical
connection and a large surface area.

EMC-compliant connection of the converter
EMC-compliant installation of the inverter and motor are required in order to ensure
disturbance-free operation of the drive.
Install and operate inverters with IP20 degree of protection in a closed control cabinet.
Inverters with degree of protection IP55 are suitable for installation outside a control cabinet.
An overview of control cabinet installation and cabling can be found in the following section.
For further details, refer to the installation instructions of the Power Module.
The EMC-compliant connection of the inverter itself is described in the following sections.
