● Terminal box or connectors, variant with at least IP54 according to EN 60034
● Flexible tube
● Ground cable with cable lug
6.2.4
Connection cables
In the standard version, the stator core has the following connection cables:
● Power connection marked U1, V1, W1
● Two cables for the temperature sensor (one reserve), two-wire with color coding, each
cable cross-section 0.22 mm².
Note
Electrical connection via terminal box or power connector
The power cables of the motor are not suitable as direct electrical interface of the spindle.
The electrical connection of the spindle must be made via the terminal box or power
connector.
● Feed out the free cable ends from the spindle box in a suitable protective tubing with
cable gland to a terminal box provided by the customer.
● Ensure effective strain relief. Maintain the required minimum bending radii (3 to 4 x the
outer cable diameter).
● To connect the motor to a converter, use MOTION-CONNECT cables or shielded
connecting cables from the spindle box interface.
Note
The maximum length of the connecting cable is 50 m with and without VPM.
● Due to the high voltages, use cables for higher mechanical requirements in combination
with a connection socket and VPM.
