Rockwell Automation 1394 SERCOS Interface Multi-Axis Motion Control System Installation Manual - Manual (Page 109)

Publication 1394-IN002B-EN-P — February 2004
Specifications and Dimensions A-5
To avoid nuisance tripping, refer to the following table and select the
appropriate combination of system module, supplementary circuit
protection device, and axis modules.
Fuse Specifications
Contactor (M1) Specifications
1 Consider using a 60A contactor when the total capacitance of the axis modules is greater than 880 µF.
2 x indicates coil voltage.
3 A surge suppressor is required.

1394C-SJT05-D
1492-CB3-H300
Any combination of AM03 and AM04 up to 4 axis modules. Any
combination of AM03, AM04, and AM07 where no more than two
AM07s are being used. Use of other combinations of axis
modules with this system module may result in nuisance tripping
on power up due to a higher inrush current.
A 1492 device is not
recommended for this
option.
Other combinations of AM07, AM50, and AM75s. Some local
electrical codes require that the circuit breaker rating not exceed
400% of the full load device current. The inrush current draw of
the 1394 in some combinations exceeds the 30A breaker and will
result in nuisance tripping.
