Technical description
The supply module feeds field power through the power jumper contacts. Ma-
ximum current supply to the modules with fuse holder is 6.3 A. Should more
current be needed, additional supply modules may be added in the assembly.
Changing the fuse is accomplished by pulling out the fuse holder and remo-
ving the fuse. A blown fuse is indicated by a LED.
The 750-610 and 611 modules send information about the status of the supply
module to the fieldbus coupler through two digital input bits.

Make sure the proper voltage is applied to the supply module. Use caution
when changing potential within the node. All modules following the supply
module will be powered at the new potential. The following table shows the
voltage ratings for the supply modules.
