3.5.2 Three-phase Motors
For SC 15 D / 30 D / 60 D only
Be sure to install a reliable main disconnect switch (or breaker) which
meets the IEC standard for emergency stop. Failure to do so can cause
damage or fire.
CE Requirements
The 3-phase motor is not protected. External protection must be provided.
■
Min. circuit current capacity of the conductors is:
SC 15 D - 3-phase 7 A
SC 30 D - 3-phase 15 A
SC 60 D - 3-phase 15 A
■
The main circuit breaker must be rated for the following maximum currents:
SC 15 D - 15 A
SC 30 D - 15 A
SC 60 D - 15 A
Protect the motor by installing the recommended breaker. Failure to do so
can result in injury from electrical shock or fire.
Use a power cord and ground wire of over 2 mm
2
(rated at 7 A, 3-phase for
SC 15 D) / (rated at 15 A, 3-phase for SC 30 D) / (rated at 15 A, 3-phase for
SC 60 D).
When using power cords which are only rated for lower currents, there then
exists the risk of excessively heating the wires (risk of starting a fire).
Firmly fit proper round crimp style terminals to electric cord using the
appropriate tool and connect to motor terminal. If the connection is loose,
it can cause bodily injury or electrical fire
