1394-System Module Input Power Wiring When Not Using Axis
Modules
The figure below shows how to wire the 1394 system module for
input power when no axis modules are used. The transformer is rated
for 480V AC secondary and 500 VA. The fuse is a Brush (Bussmann)
600V AC, 10A (FRS-R-10A). The contactor is an Allen-Bradley
Bulletin 100-C12x10 contactor.
