4.5 System Output Earthing

The MX06 40A Shelf has its output earthed as default. The output is earthed by the earth cable joining the earth stud to the output earthing bus-bar (as shown in the above picture). The earth link can be removed to leave the output floating but the user must then earth the output at some other point in the system.

The default configurations are as follows:

54 V systems are set to earthed positive output

27 V systems are set to earthed negative output
