Connecting
4.1 System connection
Death or severe personal injury from electrical shock
The earth leakage current for the drive can be greater than AC 3.5 mA, which may cause
death or severe personal injury due to electrical shock.
A fixed earth connection is required to eliminate the dangerous leakage current. In addition,
the minimum size of the protective earth conductor shall comply with the local safety
regulations for high leakage current equipment.
Adjusting cable directions from the motor side
For some low inertia motors and all high inertia motors, you can adjust the direction of the
power cable, encoder cable, or brake cable from the motor side to facilitate cable connection.
The following illustrations take high inertia motors with the incremental encoder for example
to show how to adjust the cable directions.
Low inertia motors with a shaft height of 50 mm and high inertia motors with straight
connectors
Note
Rotating the connectors
You can rotate all the three motor-side connectors only within 360°.
